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. The suitable package is used for proper winding are called winding package.
Types of Winding Packages
- Parallel Winding
- Non Parallel Winding
- Cross Winding
Parallel Winding Package
In this type of winding the yarn is wound parallel to each other on package containing flanges on both sides. This type of winding does not require traversing guide.
Advantages of parallel winding
• many yarns can be wound at the same time
• no need of traversing guide• no change in yarn twist occurs
• the package is stable
• side withdrawal is possible
Disadvantages of parallel winding
- flanges are required
- separate mechanism is required to unwind the yarn
- over withdrawal is not possible
example: beam, flange
Non parallel Winding Package
This package contains one or more threads which are laid very nearly parallel to the layers already existing on the package.
Advantage of non parallel winding
- flanges are not required
- over withdrawal is possible
- no change in yarn twist occurs
Disadvantages of non parallel winding
- side withdrawal is not possible
- the package is not stable
- traversing machine is required
example: cop
Cross Winding Package
This type of package contains a single thread which is laid on the package at an appreciable helix angle so that the layers cross one another to give stability.
Advantages of cross winding
- flange is not required
- yarn package is very stable
- over withdrawal is possible
Disadvantage of cross winding
- the yarn twist is changed during this winding
- traversing mechanism is required
