Yarn end placement

Index

The yarn end placement feature ensures the reliable positioning of the yarn end on the outside surface of the full package. In downstream processing the yarn end can easily be found and removed from the package by the operators. This results in significant cost savings of up to 40% for package handling in downstream processing.

Yarn end placement is performed prior to the replacement of the full package by an empty tube. The robot unwinds a certain length of yarn from the full package, which still remains in the package holder. The yarn removed is then wound back onto the package, with one layer around the left-hand side of the tube and placement of the yarn onto the package surface.
