Abstract:
A thread draw-off nozzle (1) for an open-end spinning device has a draw-off nozzle funnel (6) that contains a yarn deflection zone (3) for deflecting a yarn (5) produced during the yarn draw-off process. The draw-off nozzle funnel (6) has a two-part design, an external part (6a) containing a first area (3a) of the yarn deflection zone (3) and an internal part (6b) containing a second area (3b) of the yarn deflection zone (3). Both parts (6a, 6b) are made of different materials and/or have different coatings at least in the areas (3a, 3b) of the yarn deflection zone (3) or only one of the two parts (6a, 6b) has a coating.
