Abstract
The invention relates to a thread draw-off nozzle (1) for an open-end rotor spinning device with a front surface (16), a nozzle bore (6) and a funnel-shaped yarn deflection surface (5) connecting the front surface (16) and the nozzle bore (6). The front surface (16) adjoins the yarn deflection surface (5), and the front surface (16) and the yarn deflection surface (5) form an effective diameter (DW) of the thread draw-off nozzle (1). The effective diameter (DW) of the thread draw-off nozzle (1) is less than 8 mm, and the yarn deflection surface (5) features a radius of curvature (R) of less than 2.5 mm.
