Yarn winding method and apparatus to maintain tension during tail formation

摘要

A controlled, two-position lash point is used to maintain tension during tail formation while winding yarn. During winder string-up the lash point is in the lower "reachable" position. As the yarn is caught up on the winder to form a tail, the lash point is controlled to quickly move up to the upper winding position, thereby taking up slack during tail formation and maintaining tension to prevent breaking yarn.
