Abstract
In an open-end spinning device a yarn draw-off nozzle suitable to ensure constant spinning conditions even at very high rotational speeds is provided. This is achieved in that the yarn draw-off nozzle is designed so as to be especially capable of heat dissipation and thus being capable of preventing a heat accumulation in the area of the yarn draw-off nozzle thanks to its high capability of heat dissipation.
