  • Method and apparatus for grasping a yarn end on a cheese
    Patent number: 5765770
    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.
