Abstract

The invention relates to a yarn draw off unit of a rotor spinning machine having a draw off nozzle (21) which projects into a spinning chamber (22) of the rotor spinning machine and a draw off conduit (23) for a yarn (5) produced within the spinning chamber (22) the draw off conduit (23) being arranged downstream of the draw off nozzle (21) in the draw off direction of the yarn (5) that is drawn off from the spinning chamber (22). The draw off conduit (23) comprises a helical section (24) with the aid of which a false twist can be imparted to the yarn (5) within the draw off conduit (23). Furthermore a draw off nozzle for a rotor spinning machine is described the draw off conduit (23) of which comprises a helical section (24) with the aid of which a false twist can be imparted to the yarn (5) within the draw off nozzle (21). Finally the invention relates to a method for producing a yarn (5) with the aid of a rotor spinning machine. The method is characterised in that the yarn (5) is exposed to torque within a helical section (24) of the draw off conduit (23) said torque causing the yarn (5) to rotate about its longitudinal axis the direction of rotation of the rotation corresponding to the direction of rotation that is imparted to the yarn (5) by the spinning rotor (3).
