ABSTRACT:
Device for transferring to an empty coil core a thread continuously fed to the take-up coil of a rotor spinning machine, includes a thread guide traversible along a reciprocating path between the ends of a coil core for guiding a thread onto the coil core, a thread pickup assembly having means for picking up the thread under tension before transfer thereof to an empty coil core, the thread pickup assembly being pivotable from a location on the reciprocating path to one of the ends of the coil core, the thread pickup assembly includes a thread capturing device as well as a pair of thread severing devices respectively disposed in front of and behind the pickup means in travel direction of the thread, the thread severing devices being activatable in time sequence by movement of the thread pickup so that the thread severing device disposed behind the pickup means is activatable, after capture of the thread by the capturing device, in time coordination with the pickup of the thread, and the thread severing device disposed in front of the pickup means is activatable at an instant within the period during and shortly after transfer of the thread to the empty coil core.
