Abstract
An open-end spinning device comprises a spinning rotor () rotating in a rotor housing with a spinning insert () supported rotatably with respect to the spinning rotor () coaxially to the rotor axis (). The spinning insert () can be caused to rotate as a function of the rotary motion of the spinning rotor () via a contactless entrainment of the spinning insert () by means of permanent magnets () attached to the spinning insert (). In this manner a simple and reliable entrainment and an automatic adjusting of the rotational speed of the spinning insert () in the spinning rotor () are achieved.
