ABSTRACT:
A suction element (1) has a slit-like suction nozzle portion (20) extending transversely over a cone from which a loose thread end is to be sucked off. The element includes an airflow chamber 22, located between the suction nozzle portion and a vacuum fitting (8), in which two draw-off rollers (2, 3) are positioned, freely rotatable and driven by the air stream flowing from the nozzle opening through the chamber into the suction fitting. The soft elastic force of the suction airflow is transferred to the rollers and then to the thread or yarn being picked or plucked off so that thread breakage upon sudden changes in pull-off resistance are effectively prevented.
