Types Of Winding

Drum winding machines rotate the forming package through surface contact with a cylindrical drum , and the yarn is traversed either by an independent traverse, typically by a wing cam or by grooves in the drum.

Drum winding systems involves a significant contact between the yarn and the package forming device.Yarns that can be easily damaged by friction in particular filament yarns,are wound into packages using precision winders.

With precision winders, the package is mounted onto a drive spindle, and a reciprocating yarn guide, driven by a cylindrical cam copled into the spindle drive, is used to move the yarn along the traverse length.The reciprocating yarn guide limits the winding speed because of the inertia on reversals.

The term precision refers to the control of positioning each layer of yarn as it is wound on to the bobbin.
