Method for presenting the thread start of a cross-wound bobbin so as to be ready for grasping and device for carrying out the method

摘要

The thread start of a cross-wound bobbin can, during the passage through a transport apparatus arranged, for example, between a bobbin-producing machine and a bobbin-processing machine, be positioned on the bobbin in such a way that it is ready for an automatic picking-up operation in the subsequent machine, if the cross-wound bobbin is rotated automatically on the transport apparatus with the effect of an unwinding of the thread, and if, during the rotation of the cross-wound bobbin, the thread starting piece is grasped by means of a suction nozzle and is positioned on the bobbin run-off side with a length sufficient for the automatic pick-up and the thread tip is secured on the cross-wound bobbin.
