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.
Claims5
An open-end spinning device for spinning fibers into a yarn, the spinning device comprising a rotor housing, a spinning rotor disposed for rotation in the rotor housing for receiving the fibers to be spun into the yarn, a spinning insert rotatably supported coaxially with respect to the spinning rotor and a coupling device for contactlessly imparting rotation to the spinning insert as a function of rotation of the spinning rotor for rotation of the spinning insert at a different speed from the spinning rotor under the influence of a shank of the yarn being spun.
