1.1.2 ROLES AND RESPONSIBILITY The goods are received and unloaded at the unloading bay. The fabrics are received and stacked in “TO BE INSPECTED” area. Physical check is done on the received goods to confirm details like Style No, colour, P.O.no, weight per lot; etc which are provided in the PI(Production information) sheet. Physical check is done for 100% of the received quantity/stock. A sample swatch from the bulk is sent to buyer for approval. After Physical check the goods are transferred to their respective storage areas after which quality inspection is done. Quality inspection consists of checking the actual GSM, shrinkage, shade and colour continuity card using various testing tools. The colour continuity card is used for the purpose of dividing the fabric into various batches for avoiding shade variation within garment /batches. First Quality inspection is done on 10% of the quantity using Four point system. If the inspection criteria are not met then again 15-20% of the remaining quantity is checked. Fabrics that fail the inspection criteria are sent back to the mill for replacements as the fabric sourcing is in-house. A fabric checking machine is used for woven garments whereas for knits physical checking is done. Quality inspection takes around 2 days to complete. If one particular lot fails then fabric Dept must have details like weight of the lot and Storage area etc. Lot passed with Four point system either has to be issued to cutting with the DC as against the actual consumption determined by IE Dept. The Dept also maintains the Reconciliation Report for each Style for referencing. Record maintenance of the In-word, Out-word and Stock Record for each Style is maintained both physically and in computerized formats. Fabric Trim chart is also developed style wise to confirm required fabrics are received. Sampling fabric for sampling purposes is stored in racks different from bulk fabrics. The fabric dept mainly communicates with cutting, merchandising, IE, sampling for performing its responsibilities.

2.4 ROLES AND RESPONSIBILITY The department is responsible for making various samples for buyer approvals. Sampling starts right after Order Confirmation Meeting (OCM). The buyer tech-packs are sent to the production merchandiser who in coordination with sampling department develops requisite samples or re-engineers the existing one. Based on the requirement of buyer various samples are prepared before production. Department analyzes the tech-pack received and prepares patterns accordingly on CAD (Computer Aided Design) or manually. During the pattern making fabric analysis is done and ordered for sample development. Accordingly samples are cut and tailor stitched. After the samples are created they are sent to the merchandiser for buyer approval. The comments given by the buyer are analyzed and acted upon. Sampling ensures that anything that goes into production is approved with no further changes. The tailors are in three groups with each group developing single sample. The approved fit sample is sent to the IE department for production feasibility and costing purposes. After confirmation on the PP sample the production merchandiser creates the PI sheet including buyer comments received. Records regarding incoming fabric, samples developed and samples despatched are maintained on a regular basis.
2.5 TERMINOLOGIES •
Tech-packTech-pack- It is a document document provided by the buyer buyer that contains details details such as measurements, fabric and trim details, technical and construction details and packaging details.
•
SamplesSamples- The various types of samples prepared are:

Size set- This consists of a group of four to five graded sizes. This is required to obtain approval on the grading of sizes. Any comments received on fit samples are applied here. These samples are made from actual fabric, trims and packaging materials exactly as per techpack.
o
Pre-Production (pp) sample- This is the final sample developed with all comments received from the buyer using actual trims and fabric. This is the last sample in which changes from buyer is accepted. This sample acts as reference for production. It is developed with strict adherence to the tech pack. After approval a FFP (fit for production) seal is put up on it. It then is called the FFP sample.
o
TOP (top of production) sample- This sample is the top most sample from the pilot run from a real production line. Buyer approval is required on this sample in order to proceed further. The purpose of the sample is to determine whether all requirements are met while mass production.
o
Concept sample- It is the first sample created in order to present the fit and concept of the garment. It may be developed in substitute fabric and trims. The measurements can be in i n tolerance range.
o
Red seal- This is similar to size set samples of two to three sizes with fit conformance. The sample can be developed in substitute fabric and trims.

3.2 ROLES AND RESPONSIBILITIES The cad department receives tech-packs from sampling department for pattern development. The patterns are developed as per the spec sheet with style details. The patterns are developed using Gerber Accumark PDS (8.2.1) Package. Patterns developed manually are digitized using a digitizer (Gerber Digitizer). The patterns prepared on the CAD are plotted on a plotting paper by a Gerber Plotter. The plotted patterns are cut-out manually and pasted on cardboard. These patterns are used for quality checking, referencing, sampling purposes and cutting. After pattern development marker making is done on AccuNest by importing the pattern pieces and placing them as per the ratio in the tech-packs. The marker document consists of details such as length, width and percentage utilization along with a pictorial diagram of marker plan. During sampling stage the marker plan is sent to the IE department for consumption calculations. A revised marker plan is made after the bulk fabric has been received in the fabric store. The revised marker is made on the basis of the actual diameter/width received and sent to the IE department for revised consumption calculation. The final marker plan is prepared and sent to the cutting section with the sealed patterns. The CAD keeps the previously made patterns for future referencing in a stack.

4.2 ROLES AND RESPONSIBILITIES The cutting department receives the PI sheet from the Production Merchandiser which contains all the details of the order. Accordingly before mass cutting sample cutting of size set (jump sizes) is done and sent to quality department for approval. After receiving approval on the size set lay order plan/production programme is prepared and sent to the CAD, cutting and the spreader. The lay order plan is prepared as per the ratio to be cut and the quantity to be cut. The spreader refers to the lay order plan for the length, the number of plies and lays for spreading. Spreading is done either by automatic spreader (Gerber XLS 50) or manually. Spreading for solid fabrics is done by automatic spreader while for yarn dyed fabrics and striped fabrics it is done manually. The spreading is done batch wise so as to avoid any shade variation. Batch changes during spreading are differentiated using fabric strips running across the length of the lay. No splicing is done and the end bits that are left are used for the purpose of preparing piping. Relaxation spreading of shrinkable fabrics is done. These are left as spread for 12-24 hrs to relax and reduce the effect of shrinkage after cutting. Spreading for stripes, yarn dyed fabrics is done in short lay lengths matching for stripes. Cutting for solid and All Over Print (AOP) fabrics is done on automatic cutter (Gerber GT7250). The cutter is movable between 3 spreading tables from where the fabric lays are fed by air floatation. Cutting for yarn dyed, checks and stripes are cut by Block cutting. Blocks according to size of patterns are cut using a straight knife (Blue streak). The pattern pieces which can be cut on fold are widthwise folded individually and layering done and cut using half pattern pieces. It is also known as recutting. The cut pieces are transferred to the QC table where cut pieces are randomly selected from the lot and verified with original patterns. Checked lots are then sent for ticketing. Ticketing is done to identify the lay number, batch and size. These tickets are necessary to avoid shade variation and piece mix-match. Ticketing is done using ticketing machines on each part and piece. After ticketing all the parts of the garment are bought together and bundled as per their sizes and batch. A Bundle ticket is attached to the bundle which contains details like, number of pieces in bundle, lay number details, batch and other order details. Parts that require fusing, embroidery or printing are separately bundled and sent to 34
Internship at Alok Industries Ltd (Garments Division), Saily, 2010
respective departments. After the auxiliary processes are complete these pieces are returned to cutting and bundled along with other garment pieces and sent for production. The cutting also reworking section that replaces the cutting rejects from the sewing line with fresh pieces of same batch. In case of rejections of garments from finishing the cutting provides extra cut pieces with the fabric available to fulfill the order quantity. Piping for binding purposes is prepared using piping cutter machines of requisite widths. For this the end bits are stitched to form tubular fabrics on over lock stitching machines.

Production System. The machines in the sewing line are laid out as per sequence of the operations for knits and for woven bundle system is followed for small parts and UPS for assembly. Each line has supervisor responsible for managing daily production activities. Line writers are kept to track production, arrange accessories, get replacement pieces from cutting, get thread and maintain record. Usually 2 or 3 lines are tracked by one writer. Every line has a Quality checker and every three lines have a Quality assurance appointed by QC department. Operators at each workstation pick up the garment from aisle space on the right side and perform the operation required. After the operation the garment pieces are again rolled and pushed ahead through aisle space for next operation. Check points are provided at various points in the line and end line. Garments from the production line are dispatched to the finishing on hourly basis. Before finishing the line writers count the pieces produced size wise after every hour. Every workstation in the sewing line is provided with necessary work aids to make the job easier and a mechanical counter to account for the number of pieces produced per hour which is recorded by line writer. This is used to calculate operator efficiency and to find bottlenecks. Each line is provided with a production board on which hourly and cumulative production is displayed. Counter samples of the FFP sample are provided by the sampling which is hung at the beginning and the end of the line. Every workstation has a miniature sample of operation to be performed. Details of the machine and maintenance records are also hung at every workstation. Format for Traffic Light System used to track defects are provided by quality department for each workstations. Storage boxes at check points are provided for collection of rejected and alter pieces. The alter pieces are worked upon timely by the concerned operators to avoid production loss. Each line is provided with its own lighting facilities. Operators for operations are allocated based on their training and experience due to unavailability of skill matrix. If dail y target is not met, overtime system is followed wherein only males work.

6.2 DEPARTMENTWISE ROLES AND RESPONSIBILITIES •
IE- The IE department sends the Operation Bulletin and machine layout. The
quality department determines the check points (in line) by identifying the critical operations based upon the buyer comments received upon the PP sample and the complex operations. •
SEWING- Quality department assures quality production by appointing checkers, Quality control and Assurance personnel within sewing lines to monitor the production. The department also follows Traffic Light System (TLS) where in defects origin can be easily identified and rectified. In the TLS each workstation is equipped with the TLS format card. This card contains details of the quality that is being produced from the workstation. The quality control personnel is required to randomly check six pieces for six times during the shift. There are six circles in the format for each inspection which is coloured as per the number of defects found. There are three colours that represent the result of inspection. •
Red – if found two or more defects
•
Yellow – if found one defect
•
Green – if found no defects.
Due to this it is called Traffic Light System. Using this system the QC can identify the workstation where quality issue originates. In case of Red colour the production from the workstation is stopped and solutions are looked for. The QA personnel look after major quality concerns and checks the details of the End Line checking. The QC is also responsible for developing AQL reports at the end of the shift based upon buyer AQL levels at end-line checking. The QC based upon his estimates for the production of the day, selects the required produced pieces criteria and determines the sample size for the AQL. QC then randomly inspects throughout the day of the required sample size and compiles the AQL report. The AQL report is generated similarly for in-line checking by the checker. The AQL reports helps in classifying the defects into critical, major and minor criteria. The quality also approves the size set pieces during pre-production phase. 44
Internship at Alok Industries Ltd (Garments Division), Saily, 2010
•
FINISHING- Quality department is responsible for checking that all the buyer requirements are met before dispatch. The quality is checked after pressing, folding, and packaging. After pressing the garments are sent to the final checking tables where teams of checkers check the garments for various defects. The defects found are classified and segregated for Spotting, Alteration, Mending and Rejection. Minor spots are mended on the checking table using petrol guns. The alterations are sent back to the respective lines based on the line number sticker attached under the label by the end-line checker. Mending is done done on a separate separate table after after which checking checking is done again. Rejection pieces are sent to the rejection room and recorded. Each Checker a sticker under the garment label containing a number specific to the checker himself. Then after checking the garments are sent for tagging. After folding it is checked whether it has been done as per buyer requirements. Similarly various stages of packaging also checking are carried out to ensure adherence to buyer compliance. compliance.
•
CUTTING- Quality department regularly checks the cut pieces as per the patterns provided by the CAD. Department is also involved in the pre production phase where before bulk cutting, size set samples are approved before and after pressing. The quality checks the markers before cutting to ensure all requisite parts of the particular style are present.
•
FABRIC STORE- Quality department conducts inspection of received fabrics using Four point system and gives the reports on the feasibility on usage of the fabrics. It prepares colour continuity card for shade variation in the received lot and divide them in respective batches. They also check the GSM (knits), width/diameter and length (woven). They look for knitting, dyeing and finishing defects in the fabric. A lot of fabric after arrival goes through 10% of lot inspection. If positive, fabric is approved for production else it is subjected to 25% inspection excluding the previous 10%. If fabric fails then it is subjected to 50% checking excluding previous checked lot failing which the fabric is sent back to mill. On roll diameter variation is also recorded and minimum diameter is recorded as cuttable diameter. Usually 1- 1 ½ “of fabric end is left while measuring cuttable diameter due to end gumming and end

7.2 ROLES AND RESPONSIBILITIES The garments from the end-line after counting are bought for stickering. In the stickering process all the tickets on all the garment parts are removed and only a single ticket is left at the centre neck/waist band label of the garment. After stickering the garments are sent for pressing. Steam press are used for pressing. During pressing the pressers ensure that the size of each garment parts are within tolerance for this purpose they are provided with hard paper scales having size markings for different parts of different sizes by quality department. The pressed garments are counted and stored. Then these garments are sent for 100% final checking where all possible defects are checked. The faulty garments are divided into SPOTTING, ALTER, MENDING and REJECTION. Rejections are sent to the rejection room and recorded. Alters are sent back to the lines from where they have been produced for alterations required. Mending of defects such as small holes, torn yarns and contamination removal are done. Minor spotting is done by the final checking itself by using petrol guns. In case of major spots it is sent to the spotting rooms. Spotting room is equipped with two specialise spotting machines that can be used to remove various spots by the use of various chemicals. Then these garments are sent back for pressing. After final checking Tagging is done wherein different tags such as barcode tags, buyer tags and price tags are attached with the help of plastic lock tag pins. Folding is done as per buyer approval. An approved folded sample is hung in the folding section. After folding garments, they are packed using primary packing materials such as poly-bags, hanger and packing box. After primary packaging the packed piece are sent to packing section by passing them through a metal detector to avoid metal contamination. In the packaging section secondary and tertiary packaging such as blisters and cartoon packaging is done. As per buyer requirements after 80-100% packaging final inspection is performed on the packed lot. The final inspection is performed by a third party approved by the buyer. The inspection is performed on the AQL level decided by the buyer. The inspection is of destructive nature where the whole sample size is completely checked for any possible defects. Based on this inspection the shipment is approved. The inspected garments are repacked and sent to dispatch. Reports such as daily rejection, finishing and packaging reports are maintained. 48

8. MAINTENANCE MAINTENANCE 8.1 ROLES AND RESPONSIBILITIES The maintenance department looks after all the machines in the garment division. The department is mainly responsible for: o
Machine maintenance,
Preventive maintenance, and
Break down maintenance.
The maintenance department follows various procedures to ensure that the machines are in working condition and do not breakdown regularly. The department is divided into two parts: o
Needle and spare parts department and
o
Maintenance and repairs department
The needle and spare parts department is responsible for storage and issue of needles and machine spare parts. Department follows a ZERO NEEDLE POLICY. In this policy it is required to find all the parts of a broken needle before replacing it. The policy has been implemented as per buyer requirements. In case a needle breaks, the operator reports to line supervisor who in turn reports to the maintenance. A mechanic is issued a set of needles for replacement purposes along with a reporting chart for each needle box. Whenever a needle is replaced all the parts of the broken needle are pasted on the chart along with signature of the supervisor. Only when the mechanic returns completely filled report with all the broken needle parts of the replaced needles is he issued a new box of needles. In case the needle parts are not retrieved as per rule the supervisor and the mechanic must check within two meter diameter for 15 minutes and also check all the garments within this range by a magnetic bar. If the parts are still not found then the contaminated garment of this range are passed through large metal detector. If any garment is found with needle contamination it is separated and then the quality department checks the pieces by hand metal detector and keeps the record and these garments are rejected.

The fabric consumption calculation is done at two stages. First, before the fabric is ordered and second, after the fabric is received and inspected. After order confirmation the marker plan is made by the CAD and sent for consumption calculation by the IE department. The department calculates the fabric consumed per piece as per the marker provided with required wastages. The calculations for knits and woven are done separately. {(LENGTH X WIDTH X GSM) / 10000}/ NUMBER OF GARMENTS = CONSUMPTION PER GARMENT (KNITS) o
Length –length of marker
o
Width – width of marker
o
GSM – grams per square meter of fabric
o
Number of garments – number of garments in the marker 55
Internship at Alok Industries Ltd (Garments Division), Saily, 2010
LENGTH OF MARKER / NUMBER OF GARMENTS (IN MARKER) = CONSUMPTION PER GARMENT (WOVEN)
In the pre-fabric booking phase the details of the fabric are provided by the merchandiser as given by the buyer. Consumption per garment is calculated and fabric is booked by the HO merchandisers based on this consumption. In the postfabric receiving phase the actual fabric details like Diameter, GSM, Length, Width, etc of are sent to the IE for revised consumption calculation. Revised markers are also prepared by the CAD based on the fabric received and sent t the IE. The IE crosschecks the consumption requirements and informs the merchandiser in case of any irregularities. In consumption calculations the fabric width wastage for knits is taken to be 2” and for tubular 1”. The wastage added to the consumption per garment for knits is 5% and for woven 3%.
9.1.1.2 Thread consumption calculation – Thread consumption calculation is done on an estimation basis. The consumption is calculated in the pre-production phase. The fit sample is provided to the IE by the merchandiser. The consumption is calculated by using machine consumption ratios and seam length. The machine ratios determine the consumption per centimetre of a particular seam. The consumption is calculated with wastages up to 30% for all the thread types used in the garment. The consumption per garment is calculated and sent to the merchandiser, who in turn prepares the consumption for the order quantity and sends it to the thread store for thread booking purposes.

9.1.2 Line setup – During the pre-production phase IE performs various functions such as preparation of OB (operation bulletin), preparation of SAM’s, determining type and the number of machines required. 9.1.2.1 Machine layout – Before starting with the production IE determines the layout of the machines on the sewing line. This is based upon the sequence of operations required. The number of machines required is calculated on the basis of pitch time calculations. The pitch time is calculated as the sum of SAMs of the garment divided by the number of operations and then a comparison is done between the pitch time and the SAM of each operation. If the SAM value is more than the pitch
Pitch time = SAM (garment) / number of operations Number of machines required = SAM /Pitch time
time then the machine required would be equal to the division of the SAM by the pitch time, else a single machine is required for the operation. The machine layout chart consists of the operation names, machine names with attachments, SAM (expected) and target per hour. The estimated SAMs are provided using PDTS (pre determined time standards). The SAM of the garment is calculated as the sum of SAM of all the operations. And the production target for each operation per hour and per day is calculated based on the expected efficiency. 9.1.2.2 Machine set-up – After the machine layout has been prepared the IE department in co-ordination with the maintenance department gets the machines set in the lines as per layout. The IE in co-ordination with other departments ensures that the machines are properly set for production with right attachments and settings. 9.1.2.3 Line balancing – After the line has been set, IE looks after the production of the line to check whether any operation requires more or less machines. This is done for the purpose of optimization of production and efficiency to appropriate levels. IE also performs time study to determine the actual SAM to compare with the estimated value for this purpose.
57
Internship at Alok Industries Ltd (Garments Division), Saily, 2010
9.1.3 Productivity and efficiency management – IE looks after the production and efficiency of the lines to help the production meet its target and deadlines. Various tools used for this purpose are time study and method study. 9.1.3.1 Time study – It is an analysis tool for measuring the actual time for each operation.
The time study is done done using a stopwatch stopwatch and recording recording sheet. It It is
normally performed a week after line start-up. The time study is performed by ten continuous cycle time recording for each operation. Average for these values is calculated and a rating is given to the operators work. Based on the rating and the average time average time is calculated. Allowance factors are allotted depending upon the gender of the operator and the machine used in the operation. These allowances in combination with their basic time are used for deriving the SAM value. The time study is used for making pitch diagrams to identify bottlenecks in a line. A pitch diagram is a graphical representation of production of each workstation. The lowest point on this graph is taken to be estimated production of the line. This lowest value is also identified as the bottleneck operation. For which various steps are taken to improve its production. These steps include method study of the operation, physical check of the machine, sewing operation parameters, nature of fabric and material handling and motivation of operator to upgrade. 9.1.3.2 Method study – Method study is performed by studying the operational methods used by the operators. The main aim of the method study is to provide pr ovide easy and streamlined way of doing an operation. The method study aims at reducing wasteful or avoidable movements in order to reduce time for the completion of the operation. It is done by observing the operators initial work methods and recording the details of work method such as elemental time required for each type of motion and frequency of motion. motion. Analysing the recorded data and finding finding a feasible solution solution to reduce the manual work and cycle time a new work method is proposed. The proposed work method is tested for feasibility and accordingly implemented.

9.1.4 Costing – The IE department is responsible for costing at three stages. Query stage, pre-production stage and final costing. 9.1.4.1 Query stage costing – Query is a stage at which a buyer approaches the company for the purpose of acquiring the approximate details of the costing for a style of which the buyer proposes production. At this stage the IE provides the rough estimate on the manufacturing cost of the garment to the buyer on past data and experiences. This costing is marked up for the purpose of negotiation. 9.1.4.2 Pre-production costing – After the order confirmation the buyer decides the rate at which it will pay the company. Using this cost as the basis costing is done so as to ensure considerable profits. The costing at this stage mainly consists of material cost, CMT charges (Cut Make Trim) and profit. It is necessary at this stage to adjust the cost at lowest possible. To meet such requirements tries to keep a control on the consumption quantity of materials. The CMT charges are calculated department wise as per the machinery and labour invested. The CMT charges are also affected by the purchase of new machinery for the manufacturing of the order. CMT = {(SAM of garment) X (cost/min of factory)}/ efficiency (expected) Cost/min of factory – It is the cost of running the factory for a min.
These details are sent to the HO for compilation of cost for the order. 9.1.4.3 Final costing – This costing is the final costing done at the completion of order to calculate the cost incurred for order completion. Using reconciliation statements of various departments such as stores, cutting, sewing, finishing and packaging final costing is done to compare the cost with the one given at preproduction phase. Any kind of revision in consumption of materials and work investment that are done in-house is highlighted. If the revision is incurred due to the demands of the buyer then the cost for that is added to the buyer’s cost. The final objective of this costing is to determine profit or l oss that factory incur.

Internship at Alok Industries Ltd (Garments Division), Saily, 2010
9.1.5 Capacity planning – The IE does capacity planning during the pre-production phase in which it prepares a plan for production on monthly basis depending upon the capacity available in the factory. Capacity booking consists of balancing work between different work departments such as cutting, sewing, embroidery, printing, finishing and packaging depending upon their available capacities. 9.1.5.1 Capacity booking – In capacity booking it is checked whether the departments in the factory can meet the production requirements of the orders. It also helps in determining if the orders are to be executed in-house or be given for job-work. The capacity booking depends upon constraints such as machinery and production capacity available. It also helps in planning the work as per capacity and helps in deciding the time period up to which production shall take place depending upon various variables. In this the requisition of new machinery is also looked after if required. 9.1.5.2 Learning curve – The learning curve is used for estimating the production timeline and efficiency at which a style will be produced. There are four types of learning curves: •
Fast
•
Rapid
•
Normal
•
Slow
The type of learning curve used to estimate the production pick-up is determined by the styling of the garment. Easier the style steeper (faster) the learning curves. 9.1.5.3 Production feasibility – IE checks the production feasibility for a style during the sampling stages by checking the machine and attachment requirements. Feasibility is also decided on the basis of the complex styling of the garment. 9.1.5.4 Build up plan – A build up plan is a plan made up of daily production targets in advance for an order based upon Efficiency, Learning curve, Capacity and other production variables. It is represented in a timeline format with daily as well as cumulative production target. It i s prepared separately for each department.
60
Internship at Alok Industries Ltd (Garments Division), Saily, 2010
9.1.6 Incentive planning (workers incentive) – An incentive is awarded daily to operators for meeting or exceeding their productions targets. The incentive is awarded on various criteria such as SAM of the garment and minimum incentive quantity. Incentives are allocated using incentive slabs based upon range of SAM. The range of SAM decides the product category. Incentive plan is based on these product categories. For example a garment with a SAM of 12.5 min will lie in a category of Product 4 (12-14 min). According to the product category for minimum incentive minimum production per tailor is decided. The target to be achieved to be eligible for incentive is calculated as product of the number of tailors and target per person. If the actual production of line is more than the target then production per person is found and the incentive rate is selected in the incentive rate slab under the appropriate product category. The total operator incentive is calculated as the product of the incentive rate and the total production and incentive per operator is calculated by dividing this value by the number of operators. Per helper incentive is calculated as half the value of per operator incentive.

1. Estimating Thread Consumption
INTRODUCTION It is important to know the amount of thread consumed in a sewn product so as to estimate requirements for manufacturing finished product. Thread consumption can be determined in several ways. To calculate the amount of thread in a seam: 1) Measure the actual actual amount of thread consumed consumed in a specific specific length of seam. seam. 2) Calculate the thread consumption by using mathematical stitch formulas based on the thickness of the seam and the number of stitches per inch. 3) Calculate the thread consumption using thread consumption estimates.
ESTIMATED THREAD CONSUMPTION
Estimated thread consumption is calculated using thread consumption factor values of various machines. A specified length of the seam, for example 3 cm is measured on the seam and the thread is removed by carefully unravelling the stitch. Then the amount of thread consumed in one centimetre is multiplied with the factor times the total length of the seam measured in cm(s). The factors for each machine/stitch type is estimated average values based upon a middle SPI.These factors are an average value of thread consumed in a cm of a particular seam .
If different types of threads are used in the garment then it’s necessary to differentiate the consumption per thread. This differentiation is done at the seam calculation stages when the consumption per seam is calculated by the help of consumption percentages for needle bobbin and loopers per machine t ype. If in case spreader is used in case of flatlocks then the consumption for looper and spreader is evenly distributed.

I.E. dept. receives the garments from the merchandiser after the approval for fit/size set is received. The calculation calculation for consumption consumption (fabric, thread) and S.A.M value is done following the receival.
2. Formation of operation bulletin The first step in thread consumption calculation is the formulation of the operation bulletin(OB).This helps in identification of various seams seams used in i n the garment. 3. Measurement Measurement of the seams and recording recording The seams identified in the previous step are measured using measuring tape. The measured seams are recorded accordingly. The measurements are carried out in centimetres (cms). (cms). This iis usually usually done to ease the work work of calculation calculation as
the
factors are available for per cm. 4. Identification of thread types As garments may contain/made up of different kinds of threads its necessary to identify locations where different types of threads are used in order to quantify their consumptions required for placing orders for purchase purposes. 5. Format development for calculation An

6. Data entry for calculation Data relating to the seam lengths and the factor corresponding to the type of seam used is entered into the excel sheet format developed. The factors are referenced from the standard factors readily developed by the IE dept. 7. Thread consumption distribution The distribution of consumption consumption as per the threads required required in each seam is done by typing the consumption consumption formulas in the corresponding thread columns.
Fig 2.2 - Example of thread distribution
8. Calculating consumption The thread consumption per seam is calculated using the formula: Total consumption (mts) = (seam-length (S.L)(cm) X factor(per cm)/100) X No. of seams
The formula helps in formulation of total thread consumed in a seam irrespective of the types of threads used. To segregate the consumption of different threads used in needle, bobbin and spreader the following formula is used:
Consumption (mts) = Percent consumption Per seam of needle/bobbin/looper X Total consumption in seam
84
Internship at Alok Industries Ltd (Garments Division), Saily, 2010
Based on consumptions of needle bobbin and spreader the consumptions are allotted/allocated to the thread t hread type used. 9. Formation of report report for merchandiser merchandiser Calculated thread consumption consumption is compiled into into a suitable report format format so as to be sent to the merchandiser for the purpose of booking the thread for a required amount of thread quantity. The IE dept only calculates per garment consumption for a single approved sample of a particular size.
85
Internship at Alok Industries Ltd (Garments Division), Saily, 2010
3. Identification and analysis of key areas of concern in calculation. It is necessary to identify various variables involved in the calculation process required as these variables influence the consumption. The various variables involved are as follows:
⊕
•
Seam – Length measurement measurement
•
Wastage percentage
•
Thread distribution per seam (needle/bobbin/spreader).
•
Type of seam , garment and fabric type
Seam-Length measurement measurement
The seam length is an important factor influencing thread consumption. Seam length also determines how much waste and extra per seam of thread will be consumed. Preferably extra length is taken so as to consider the wastage during making the seam. ⊕
Wastage percentage
The wastage percentage is an important factor that helps determining the wastage required to cover the waste waste during production. Generally the wastage is taken to be 30 % of total consumptions. consumptions. ⊕
Thread distribution per seam (needle/bobbin/spreader)
The distribution of thread per seam (i.e. needle /bobbin/spreader), is a necessity for the purpose of determining and quantifying the amount of thread required. Any variation in the distribution can lead to less/more consumption of a particular thread. ⊕
Type of seam/Garment and fabric type
The consumption also depends on the type of seam as different seams have different factors and thus the consumption variates. Any error in identification can lead to wrong consumption calculations. Consumptions also depend on the fabric type and garment construction technique as a light weight and difficult constructed seam have more consumptions as there are chances of error occurrences in them.

This data was provided by the IE dept of Alok industries Garments division. A separate worksheet named “factors“ had been developed for the purpose of tabulating the data of thread consumption ratios.

Referencing
Cell referencing has been used in order to reference values from one cell to another for purpose of creating the report, calculations and retrieve values in controls.
5.3.4.3
Programming Programming tools
Visual basic controls like command button and combo box list have been used for the purpose of proving various functional f unctional features. Combo boxes have been used in columns like m/c selection, spreader used, needle, bobbin and spreader thread descriptions. These boxes help in easy and quick selection. Command buttons have been used to provide functionality such as saving, resetting fields and generating the report.

CONCLUSION /DELIVERABLES
The thread consumption consumption calculator is an easy easy to use and and efficient tool tool to calculate thread consumptions. The calculator provides a hassle free interface for selection. A standard format helps in data entry purposes. A human error in data entry reduces r educes to only the seam lengths, number of seams and the seam type.
The calculator report
also provides a systematic systematic report of the consumption consumption
calculated. It also reduces the merchandisers work of compiling the consumption consumption for order quantities based on the consumption per garment given by IE. The report can also be helpful in thread booking purposes purposes which can be sent to the thread store by the merchandiser from where the thread store can proceed with the process of thread booking.

LEARNING EXPERIENCE The internship in many ways provided a platform for new experiences in terms of industrial exposure exposure as well as personal experiences in terms of tour and travel to to new places and accommodating ourselves into the busy schedules which otherwise are not experienced in college. Industrial exposure not only drove our curiosity to know more than our limited textual knowledge but even compelled to get ourselves involved in the process as a whole. The project undertaken by us exposed us to the actual working feel and conditions and helped us to tune according to the industry needs. We first were allowed to observe as much and then our doubts were cleared. Various communication techniques and industrial practices which are important for professional behaviour were learnt through our interactions with the industry officials. Our Interactions with our mentor Mr. Samuel Mupavvarapu were motivational and a inspirational interaction that fuelled our curiosity for internship with full confidence and dedication. The managers to whom we were entrusted to meet to learn about the respective dept.’s were were under huge pressures pressures of work but never did it happen that anyone would would deny us any answer to the the query which we would ask them at any point point of time, time, their such such generous generous nature helped us getting the information we required time to time.
