Abstract

An open-end spinning device comprises a spinning rotor (21) rotating in a rotor housing with a spinning insert (24) supported rotatably with respect to the spinning rotor (21) coaxially to the rotor axis (33). The spinning insert (24) can be caused to rotate as a function of the rotary motion of the spinning rotor (21) via a contactless entrainment of the spinning insert (24) by means of permanent magnets (32) attached to the spinning insert (24). In this manner a simple and reliable entrainment and an automatic adjusting of the rotational speed of the spinning insert (24) in the spinning rotor (21) are achieved.
