Thread draw-off nozzle and open-end spinning device having a thread draw-off nozzle

Abstract

An open-end spinning device having a thread draw-off nozzle and a thread draw-off nozzle for an open-end spinning device, the thread draw-off nozzle having a thread-guiding surface which extends between an entry opening and a draw-off opening and which tapers in the shape of a funnel toward the draw-off opening. In order to provide a thread draw-off nozzle and an open-end spinning device having a thread draw-off nozzle which allows controlled production of the thread, the thread draw-off nozzle has a blocking element, which protrudes from the thread-guiding surface and which has a thread stop surface designed such that the thread stop surface blocks a thread from circulating over the thread-guiding surface.
