Abstract
A thread draw-off nozzle for an open-end rotor spinning device includes a front surface, a nozzle bore, and a funnel-shaped yarn deflection surface connecting the front surface and the nozzle bore. The front surface adjoins the yarn deflection surface. The front surface and the yarn deflection surface form an effective diameter (D) of the thread draw-off nozzle. The effective diameter (D) of the thread draw-off nozzle is less than 8 mm, and the yarn deflection surface comprises a radius of curvature (R) of less than 2.5 mm.
