Winding

Definition

            The process of transferring yarn from small packages like hank, bobbing etc to a large package such as cones, pirns, cheese etc, containing considerable length of yarn is called winding.

Objects of Winding

1. Bobbin emptying operation
2. Make a continuous supply of yarn
3. Remove thick and thin places from the ring yarn
4. Remove weak places from the yarn
5. remove neps
6. remove knots
7. remove slabs

Requirements of a Winding Machine

1.     the faults should be reduced to an acceptable level

2.     the yarn must not be damaged during winding

3.     Winding should be carried out at high speed for higher productivity

4.     The knots and splices should have sufficient strength and stability

5.     The process should be economical

6.     Winding package should not be too loose or tight.

Winding Parameter

1. winding plate speed (meter per minutes)
2. winding diameter (cm)
3. Traversing velocity (meter per minutes)
4. angle of winding (degree)
5. package velocity (meter per minutes)
6. net winding velocity (meter per minutes)
