Spreading
Automatic and manual spreading with tension control.
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
- 1Confirm the marker and ply count
Check marker length, width, and required number of plies against the cutting order before starting the lay.
- 2Check 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.
- 3Set 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.
- 4Align the first ply precisely
Square the first ply to the table edges and end stops, since every subsequent ply is aligned against this reference.
- 5Spread 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.
- 6Inspect 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.
Key metrics (indicative targets)
| Metric | Working target | Why it matters |
|---|---|---|
| Ply alignment accuracy | edge variance within a few millimetres across the lay | misalignment produces out-of-shape panels in lower plies |
| Spreading tension consistency | uniform tension across the full lay length | uneven tension causes panels to shrink or distort after cutting |
| Fabric utilisation on the lay | matched to the marker's planned efficiency | poor spreading control widens the gap between planned and actual usage |
| Spreading speed vs plan | meets planned plies-per-hour for the shift | tracks whether spreading capacity supports the cutting schedule |
| End-of-lay defect catch rate | faults identified before cutting begins | catching fabric faults at this stage prevents defective panels entering sewing |
Targets are indicative working ranges, not standard or legal limits.
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
