ABSTRACT:
A textile machine includes a cheese or cross-wound bobbin winder with winding stations each having a creel for holding a cheese, a reversible rotary cheese drive, a suction nozzle and a swivel drive for swivelling the suction nozzle to the jacket surface of the cheese. A method for grasping a yarn end resting on the cheese includes adjusting a search time during which the inward-swivelled suction nozzle is positioned at the reverse-rotating cheese, in dependence on the instantaneous diameter of the cheese, and on the reverse speed of the rotary cheese drive, which is kept constant over the entire search time. An apparatus for grasping a yarn end resting on the cheese includes a control device, control lines connecting the reversible rotary cheese drive and the swivel drive of the suction nozzle to the control device, and measured value pickups at each winding station for recognizing a predetermined number of cheese revolutions, for detecting the speed of the rotary cheese drive, and for recognizing the swivelled position of the suction nozzle.
