Abstract

A method, and associated textile machine winding station, are provided for handling a yarn end of a cross-wound bobbin at the winding station, wherein the cross-wound bobbin is held and driven in a bobbin holder. A thread is laid in a cross-wise manner on the cross-wound bobbin by means a traverse device. A suction nozzle having a movable suction mouth is subjected to negative pressure, and the suction mouth is moved relative to the suction nozzle such that a distance between the suction mouth and the cross-wound bobbin is changed in order to find the thread end on the cross-wound bobbin and to suck the thread end into the suction nozzle, or to stretch the thread end sucked into the suction nozzle between the suction mouth and the cross-wound bobbin. The stretched thread is moved to a unit of the textile machine for further processing.
