What really happens at this stage

Spreading lays multiple plies of relaxed fabric on the cutting table to the marker length, forming a lay from which the marker will be cut, and the method chosen (manual or automatic) affects tension, ply alignment, and fabric utilisation. Manual spreading relies on operators walking the table with the fabric roll, controlling tension and edge alignment by hand and eye, and is common for low-volume or highly variable fabrics where a machine spreader is not cost-justified. Automatic spreading machines travel the length of the table on a track, unwinding fabric under a set tension and speed, cutting or turning the ply at each end, and are generally used for high-volume, stable fabrics where consistent tension across hundreds of plies matters more than manual flexibility.

Tension control is the central technical concern in spreading, because fabric spread too tight will relax after cutting and cause panels to shrink below the marker dimensions, while fabric spread too loose introduces excess fullness that distorts panel shape and wastes fabric. Ply alignment at the table edges and ends must also be checked continually, since misaligned plies shift the effective cutting line for lower plies in the lay and produce panels that are correct on top but out of shape underneath. Spreading also has to account for fabric face direction, nap, and any one-way print or pile, which determines whether the lay is spread face-to-face, face-up only, or in a one-way configuration matching the marker.

How it is done

  1. 1
    Confirm the marker and ply count

    Check marker length, width, and required number of plies against the cutting order before starting the lay.

  2. 2
    Check fabric direction requirements

    Identify nap, pile, or one-way print requirements from the marker and set the spreading mode (face-up, face-to-face, or one-way) accordingly.

  3. 3
    Set spreading tension

    For automatic spreaders, set tension and speed to the fabric's recommended parameters; for manual spreading, train operators to maintain even, minimal tension by hand.

  4. 4
    Align the first ply precisely

    Square the first ply to the table edges and end stops, since every subsequent ply is aligned against this reference.

  5. 5
    Spread and check alignment periodically

    Stop at intervals to check edge and end alignment across the ply stack, correcting drift before it compounds over hundreds of plies.

  6. 6
    Inspect the completed lay before cutting

    Check total ply height, alignment, and any visible fabric fault carried over from inspection before handing the lay to the cutting operation.

Control points to check and sign off

  • Marker specification and ply count are confirmed before spreading starts
  • Fabric face, nap, or one-way direction is set correctly for the whole lay
  • Spreading tension is checked and consistent from first to last ply
  • Ply alignment at edges and ends is verified at regular intervals
  • Completed lay is visually inspected for faults before cutting begins

Common pitfalls and their consequences

  • Spreading fabric under excessive tension, causing panels to shrink below marker dimensions once tension is released after cutting
  • Ignoring nap or one-way print direction, resulting in panels that do not match when garments are assembled
  • Letting ply alignment drift uncorrected across a long lay, producing distorted panels in the lower plies
  • Running automatic spreader tension settings unchanged across different fabric types, applying an unsuitable tension to a sensitive fabric
  • Skipping the pre-cut inspection of the completed lay, allowing a fabric fault to pass directly into cut panels and sewing
