ABSTRACT:
Apparatus for assisting an operator in doffing a yarn package from a textile winder, the yarn being wound on a hollow tube; the hollow tube in turn being mounted on and rotatively locked on a winding mandrel of the winder and having an end portion of the tube extending axially outwardly of the end of the winding mandrel. The apparatus comprises an abutting member for insertion within the extending tube end portion for abutment against the winding mandrel end and a series of gripping members concentric with the abutting member and actuatable for expanding radially outwardly into gripping engagement with the inside surface of the tube end portion. Upon being actuated into gripping engagement, the gripping members are caused to be rotated forcing the yarn package into counterclockwise (as viewed from the front of the winder) rotation relative to the winding mandrel to release the yarn package from its rotatively locked position on the mandrel, and as the gripping members and yarn package are being rotated, either the abutting member is or the engaged gripping members are caused to move in an axial direction relative to the other for withdrawing the yarn package from the mandrel. In one embodiment the abutting member is caused to be moved forcing the gripped tube into retraction from the mandrel; and in the second embodiment the gripping members move in retraction from the mandrel relative to the stationary abutting member.
