Fabric lay
Spreading means the smooth laying out of the fabric in superimposed layers of specified length and after spreading the shape of fabric plies is called fabric lay. During spreading the number of plies should not be more than three hundred.

Types of fabric lay:

1. According to construction:
  • Straight lay: In straight lay each ply of fabric is spread according to marker length, i.e. all plies can have the same length. In that case one marker is used.

  • Stepped lay: Ply of fabric lay is not spread according to marker length, i.e. when the plies are laid up in different lengths- a step can be formed. Different types of marker are essential for different steps. Its use is very much less because of fabric wastages and lay making if difficult as well.

2. According to the direction of spreading
  • One way spreading (Face to underside): This method is used for open fabrics. The face can lie towards the top or bottom, but always in the same direction. If spreading machines are used, one way laying-up necessitates idle motion because the machine always begins its run at the same end of the table and must return to this position after every laying operation.

  • Laying-up in pairs (Face to face): This method is also used for open piece goods. The face side is always laid onto the previously spread face side so that- as in one way spreading- the machine returns running idle to the working position. The roll of fabric must be turned before the next piece is laid-up. When using spreading machines, these consequently require a device to turn the roll after the fabric has been cut off at the end.

  • Lap (Continuous, Zigzag) lying: This method was also developed mainly for spreading open piece goods. Contrary to one way spreading and laying-up in pairs, the pieces are not cut off at the lay end but are clamped and then continuously laid in laps. This is the easiest and most popular way of spreading.
