  • the inventive method described in claim 1 for operating a job of a cross-wound textile machine has the particular advantage that with such a method in a simple manner and without the area of the winding device is inaccessible by additional facilities, it can be avoided that it occurs From winding interruptions to the emergence of falling threads comes. That is, by the immediate retraction of the thread guide in a predetermined, advantageous position ensures that even with a thread break falling threads whose removal would make a manual intervention of the operator necessary, do not occur.

That is, the finger thread guide 13 is already in the position M when the upper thread runs onto the cheese 5. The rapid positioning of the yarn guide finger can ensure that even after a yarn break the thread end of the upper thread connected to the cheese 5 is always in a range in which it can be reached through the yarn suction nozzle 35 of the winding unit 2.
