    CUTTING SECTION SOP

    Inputs Details related toFabric such as face side/Shade bands etc..

    1. Shade swatches along with the face side

    swatch approved by the buyer should be received from the

    Go down and Merchandising dept respectively.

    2. Shade segregation should be complying with the approved

    swatches.

    3. Verify whether the shade segregation is matching to

    the standard.

    4. Approval from H/office mandatory if the received lots of

    fabric are not matching to standards.

    5. The approval must have a checklist form for all the tests

    & approval standards w. r. t colour, wash, embroidery,

    printing, hand feel

    6. Shade band details (Shade A, B, C, D) after verification

    should be received from fabric inspector & spreading team

    also should be given a copy for reference.

    7. Shade grouping also must be received from the fabric

    godown.

    8. Fabric details such as to face/back, nap direction; hand

    feel should be received from the godown duly approved by

    the merchant.

    9. Shade wise/widthwise segregated rolls only should be

    received, checked & then should proceed for laying.

    2/24

    10. Both ends of every roll should have sticker consisting

    details of shade no, roll no, width and other relevant detail

    to enable easy identification of rolls.

    Cutting Forecast shade wise

    1. Cuttable quantities from each lot and shade should be

    informed to marketing, QA, & Buyer QA in advance for

    approval.

    2. Cutting of rolls/bales should be done shade wise as per the

    breakdown of the PO

    Note: Rolls should be allotted in such a way that no of shades included

    in a single lay or shipment or size range is minimized.

    Spreading of fabric for

    Relaxation

    1. Unroll the fabric from rolls & lay on table/flat area in

    concentric folds.

    2. Allow for free relaxation without any obstruction the

    period should be studied and pre determined by the Godown and the factory Fabric Inspector

    3. Record the time of unrolling and ready time laying of each

    roll

    4. Relaxation of the lay should be pre determined and will be

    around 3-6hrs (for stretch fabrics if necessary especially

    for knitted fabcrics

    Fusing-Study of FusingShrinkage

    1. Cut fabric swatches with square template of size 18

    X18(or 12x 12)

    2. Fuse the fabric & specified interlining at specified

    temperature, pressure & time.

    3. Allow for cooling of the fused parts.4. Check for fusing shrinkage and record same ---this should

    be incorporated into the patterns as allowance for fusing.

    5. Check for shade variation if any due to fusing. If you

    observe any shade variation, report to the Cutting In Charge

    and initiate corrective action.

    6. Check the fusing for defects like peel off, bubbles etc.

    Inform deviations/defects if any to the concerned for

    necessary corrective action.7. QA team has to educate/specify area of fusing, and

    temperature and pressure to be set for fusing-

    8. Fusing tests must be carried out twice a day, once at the

    start of the machine then in the afternoon.

    Fusing Machine-- Tests & Daily Maintenance:

    >> Fusing validation trial tests must be carried out regularly,

    when the new style begins fusing parameters has to be

    finalised (temperature, time & pressure).

    >>Check the fusing machine pressure rollers nip, affecting the

    fusing quality, by passing a fabric strip through the machine &

    by pulling it backward --the need for re alignment of the

  • 8/3/2019 Systems of Ginza

    4/24

    rollers pressure can be identified when this is done at three

    points i.e left/center/right of the belt.

    >>By passing a carbon paper placed on top a white paper

    through the machine the impression on the white paper can

    be observed. This would also will help us to determine any

    inconsistence of the roller pressure at left>center> Right

    >>Cleaning of the belt thoroughly and check for the required

    temperature and pressure when the fabric/colour changes.

    Washing Shrinkage1. Percentage of washing shrinkage lengthwise and widthwise

    should be received from fabric section and recordedthe

    suppliers should ensure that the shrinkages are as specified

    by the buyers (international standard limits are 3%

    lengthwise and 3% -widthwise )

    2. Identify the face & reverse side as per the swatch . Mark the

    roll no, PO, Style, QC, Taka No etc

    3. If the washing shrinkage % is more that 1.5% then the

    shrinkage test to be conducted for all the rolls/bales

    received (100% of rolls)

    4. If there is a big variation in shrinkage, multiple markers to

    be prepared.

    For Example: For absolute shrinkage % range of 3.0 4.5 %

    marker/pattern#1 & for shrinkage of 4.5% - 6% - Marker/Pattern# 2 like that.

    >>Color codification should be done to trace rolls of shrinkage groups ,

    if the range is too large or inconsistent.

    Cutting of Pilot Run

    Objective: carried out in order to make the necessary

    amendments in patterns/laying procedure/cutting procedure

    /cutting allowance/ marker changes/panel

    inspection/numbering area/bundling size.

    1. Cutting incharge, production manager & IE shall plan for the

    pilot & bulk cutting.

    2. Pilot run cutting shall be done as per the

    colour/size/quantity advised by FM/PM/IE.-the selection of

    the rolls should cover all the shades and shrinkagegroups

    3. Make a report of observations, comments, suggestions,

    amendments, simplification, risk analysis, corrective action

    plan based on the above analysis.

    4. Obtain feed back from the sewing & buying QA and then act

    upon the necessary corrective action.

    Marker drawing &

    Preservation of patterns

    1. Carbon Papers could be used for duplication of markers in

    case of non-CAD markers.In case of Nike orders it is not

    allowed---efforts be made to obtain computer markers from

    a close by plant..

    2. The pattern/marker being suggested by HO team is only a

    starting point for the cutting incharge to work on better

    fabric utilisation. Cutting incharge should try out different

    markers to maximize fabric

  • 8/3/2019 Systems of Ginza

    6/24

    3. A Parts Checklist has to be maintained by the marker

    drawer to ensure coverage of all parts in the lay.

    4. Pattern should be verified for required allowances,

    tolerances, notches and embellishment placement marks,

    grain line, nap direction indications before marking.

    5. Constant usage of patterns results in wear & tear of pattern,

    this has to be regularly monitored and worn out patterns to

    be replaced even daily if the case demands to ensure

    cutting quality.

    6. Cello tape could be used to preserve the edges of the

    pattern boards for big quantities plastic boards could

    be used to duplicate the pattern for marker drawing

    7. If the patterns are worn out, it has to be replicated & cross-

    verified for required measurements, allowances and

    tolerances. On satisfying these factors the worn out pattern

    has to be replaced.

    8. Worn out patterns are to be destroyed after conformation

    on the correctness of the specifications mentioned in tech

    pack.

    9. Lay sheet on which the marker is drawn is torn in the

    middle & stickers are pasted consisting details like PO no,

    Serial no, Fabric code no, Lot no. Hence easy identification

    of cut panels.

    Lay Preparation:

    1. Layers shall collect lay slip, cutting job card, lay sheet fromthe minusing person.

    2. Layers shall lay the fabric according to the lay slip details.

    3. Layers shall collect rolls of only one shade and one width for

    the lay at a time ,if any shade change is noticed then use

    separators- i.e. lay sheet has to be placed for identification.

  • 8/3/2019 Systems of Ginza

    7/24

    4. The cutting incharge has to decide upon the kind of lay such

    as face-to-face, face to back, face up, face down, grain

    line, nap direction during the PP meeting stage upon the

    analysis of the garment.

    5. Use lay separator sheets to separate rolls of different

    shades if used in the same laythe shade category should

    be mentioned on every lay separator sheet also.

    Lay Precaution:

    5. During laying the layers should check the lay-to-lay shade

    variation & also center to selvedge variation as a part of

    online check procedure.6. QC shall inspect the lay for lay tension, width, length, grain

    line, nap direction etc.

    7. End wastage for laying of fabric shouldnt be more than 1

    cm.

    Bulk Cutting

    1. Lay wise manpower requirement must be planned.

    2. Cutters must be trained on the methods of accurate cutting,

    especially for parts with deep curves. If possible

    diagrammatic representation of the direction of movementof the cutter needs to be illustrated.

    3. Cutters shall inspect the cutting machine for oil leakage,

    straightness of the blade, sharpening quality, evenness in

    sharpening of the blade, dust accumulation before cutting.

  • 8/3/2019 Systems of Ginza

    8/24

    4. Cutters shall cut lay as per the mark up using straight knife

    m/c and move the parts to band knife as per the discussion

    in PP meeting.

    5. QC shall inspect all the cut parts using patterns and initiate

    corrective action upon the detection of defect.

    6. Prepare 1st cut bundle inspection report; notify fabric

    defects and cutting defects to FM/PM.

    7. QC should have a cutting checklist against which 1st bundle

    audit has to be conducted. Checklist should have details of

    allowances, tolerance included in pattern, notches and

    embellishments placement markings details.

    8. The size of the straight knife for cutting lightweight fabrics

    should be 6 only.

    9. Straight knife must be uniformly sharpened from top to

    bottom as frequently required,. This ensures even

    sharpening along the full

    10. length of the knife/blade.

    Note:If sharpening of blade is uneven/inconsistent, it would result in

    uneven depth of notch marks and variation in cutting too..

    11. For Band knife cutting , patterns preferably made of

    tin should be used.

  • 8/3/2019 Systems of Ginza

    9/24

    12. The patterns used for band knife must be changed

    regularly upon monitoring the wear and tear on the pattern,

    due to frequent usage.

    Numbering

    1. Numbering plan must be given by the numbering incharge,

    specifying the style #, colour, P.O No., Serial No., No. Of

    garments cut, sizes.

    2. All the parts shall be numbered in a pre determined

    sequence and at pre determined location.3. Numbering stickers gum strength (Light/Medium/Heavy) has

    to be decided keeping in mind the kind of fabric being cut.

    Panel Checking

    1. The checkers carried out panel checking by placing the cut

    panels on the pattern and checking for accuracy of notches,

    grain lines, nap direction, crocked cutting, measurements &

    tolerance.

    2. Mark the pattern on a board (Acrylic. Card Board) along with

    +/- tolerance as dotted lines around the outline marked.

    Place the cut panel (component) on this marked area. It

    becomes easier to asses if the cut panel is within or out of

    tolerance. This inspection board has to verified and

    approved by pattern maker before usage.

    3. Once the fabric is cut, they shall be bundled and marked

    with inspection status.

    4. When a bundle is checked, they shall be marked with green

    as c.

  • 8/3/2019 Systems of Ginza

    10/24

    5. When cut panels are inspected they shall be marked with

    green as I.

    6. All panels shall be checked for fabric defects.

    Bundling & Sorting

    1. Cuts shall be bundled in to a pre determined bundle size

    and will be segregated size wise as well as lot wise and

    stored in bags.

    2. Bags shall be stored in racks batch wise.

    3. Issues of cut bundles to batches be done out as per theloading plan

    4. Bundle tags will have details such as lot no, serial no, size,

    bundle no.

    5. Mention shade category (A, B, C) on the cut panels for easy

    identification and tracking.

    Re cutting & End bit Control:

    8. Layers shall mark both end bits with roll number, cut-lot

    number, meter age --all the bits every lay shall be bundled

    and given to recutting department.

    9. End-bits should be always laid face-up, no change in laying

    procedure without prior information from the incharge

    10. End-bits should be placed separately (Shade wise) to

    avoid discrepancies, the roll & taka number should be

    written and stacked separately

    11. Re-Cutting should be done from the same lot of fabric,

    matching the shade, to avoid shade variation.

    >> QA Team to analyze & monitor recut % day wise.

    >> QA Team to evaluate the reason for recutting & work on action plan for

    immediate implementation. Upon implementation recut % to gradually reduce

    on comparison to previous day.

    >> QA team to randomly, periodically, evaluates the panels inspected by QC &

    certifies the correctness of the decision taken.

    >> QA teams to monitor Recut % for every style.

    Audit the condition of the pattern used for marker drawing

    >> Upon usage there will be wear & tear in the pattern, this has to be

    regularly monitored to ensure cutting quality.

    >> If the patterns are worn out, it has to be replicated & cross verified against the

    requirements.

    1. DEVELOPMENT SAMPLE : (For design and fit) with available fabric2. PROTO SAMPLE: Correcting remarks on development sample andmaking another sample3. PRE PRODUCTION SAMPLE : Final approval sample for bulk production

    4. SIZE SET SAMPLES: To ckeck the measurements of all sizes

    The system starts with tech pack receiving from merchandising, review thetech pack by Industrial engineer , pattern master , mechanic and qa.

    Check the material which you are going to use for making sample ( fabric ,elastic, and accessories)

    Check the machine setting for gauge, stitch per inch , and for stitch qualityon a waste fabric before making original sample

    Check the cutting against pattern and spec sheet

    Check operation wise measurement and construction and stitch quality

    Note down the points which occurred during making sample, and how itsrectified, for production easy process

    Check the finished garment for all aspects construction, measurements,and trims placement.

    Finally review the sample along with industrial engineer , pattern masterand sampling in charge

    The sampling in charge should note down the final comments

    The QA report should me made two copies one will be for his reference andanother report along with sample should go

    The QA will be the part of any new development and in operator skill matrix

    The sampling QA and sample technician will be the part of style launch.

    Manpower requirement in sampling: Two QAs

    Under garment and swimwear one QA
