The formation of big yarn packages which can be smoothly unwound, during next process is known as winding. Winding is the most essential process both of yarn manufacturing and fabric manufacturing. The main purpose of winding is to make a suitable package for both woven and knitted fabric production. The most common packages are cone and cheese packages. Both packages are cross wound package.
Winding Mechanism in Textile:
The winding mechanism for cross winding is mainly of two types. They are-
- Random winding
- Precision winding
1. Random Winding:
The principle of random winding system is rotating winding package through frictional contact with rotating drum. This type of drive is also called surface drive.
Two methods of yarn traversing are usually employed:
- The first one is winding system with grooved drum traverse in which a drum carries spiral slots or grooves. Yarn follows the grooves cut on drum surface and is moved to and fro to traverse yarn across package length.
- The second is winding system with a plain face drum for rotating package and cam traverse in which a yarn traversing guide that follows a grooved cam moves yarn to and fro across the length of the package.
2. Precision Winding:
- The principle of precision winding is driving the package by mounting it on a spindle which is positively driven from motor.
- Traversing cam is driven from spindle shaft through a train of gears.
