ABSTRACT:
A yarn draw-off nozzle for an open-end spinning station of a rotor spinning machine includes a yarn feed region including a spiral having at least one turn with spirally extending surfaces disposed one above the other being rectilinear with respect to a yarn travel direction. The surfaces are each inclined at an angle relative to the surfaces located above and below them, defining spirally extending yarn deflection locations for supporting yarn to be drawn off.
