Bobbin

Kops is a form of coil with a sleeve ( reel or bobbin ) for ring spinning or ring twisting machines.

The Kopsform (see picture right) is achieved in that the lower part of the sleeve has a conical base is first formed, to which is then replaced alternately crossed with a layer of yarn and wrapped in parallel.

The main advantage of this technique is easy removal of the yarn from the sleeve during further processing. The withdrawal speed can in normal staple fiber yarns reach (about the coil ) to 20 m / s.

The sleeves are made ​​of impregnated paperboard or polyamide depending on the construction of the spinning or twisting positions up to 400 grams of yarn can be wound onto a core.
