Spreading Methods
THE TYPE OF SPREADING MACHINE
How to use machine?
Requirements of Spreading Process:
1. Alignment of plies in both length and width direction- length and width of fabric must be at least equal to marker length and width.
2. Elimination of fabric defects/flaws- any faults identified on the incoming fabrics will be tagged and will be avoided.
3. Correct ply direction (especially for asymmetrically printed fabrics)- all faces up, all faces down, face to face etc.
4. Correct ply tension- ply tension must be uniform and as much less as possible.
5. Avoidance of distortion in the spread during cutting- polythene sheets are used under the bottom ply to resist friction of the bottom ply with the base plate of the knife.
6. Fabrics must be flat and free from any crinkle & crease- these cause defect in garments due to variation in dimension.
7. Checks and stripes should be matched.
Automatic Programmable Spreading Machines:
All the requirements of spreading process can be fulfilled by fully automatic spreading machines. Their features include:
1. Alignment of plies in both length and width direction- length and width of fabric must be at least equal to marker length and width.
2. Elimination of fabric defects/flaws- any faults identified on the incoming fabrics will be tagged and will be avoided.

Automatic Programmable Spreading Machines:
All the requirements of spreading process can be fulfilled by fully automatic spreading machines. Their features include:
- Automatic loading/unloading and threading/rewinding device for fabric rolls.
- Automatic roll turning arrangement for face to back lay.
- Automatic leveling device for fabric edge alignment.
- Automatic cutting device (one way or two way cutoff) at the end of a run.
- Automatic tensioning device to control fabric tension.
- Automatic lay height sensing elevator.
- Programmable lay length, ply height and step-laying.
- Spreading seeds up to 140 m/min.
