ABSTRACT:
The invention relates to winding a yarn on a package. A package tray is provided which in an operative position retains the package out of contact with a package driving roller against the effect of a restoring force tending to move the package into driving contact with the driving roller. Retraction of the tray to an inoperative position so as to enable the package to be brought into contact with the driving roller is effected by reducing the restoring force.
Preferably, the invention includes open-end spinning means for producing the yarn and retraction of the tray to the inoperative position takes place during a yarn piecing-up procedure.
