CH625567

An apparatus for bringing to rest the rotor of an open-end spinning device, the shaft of which rotor is mounted in a wedge gap formed by freely rotatable support rollers and being pressed against the support rollers and driven by a tangential belt. An axial force arising from the support rollers presses the rotor shaft against an axial stop and in bringing the spinning apparatus to rest the shaft is moved away from the normal running position on the support rollers to an arrested position off of the support rollers. The shaft extends through bores provided in a pair of spaced bearings. A conically tapering section is provided on the shaft which engages a correspondingly conically shaped wall of the bore for applying an axial force to the shaft when the shaft is moved from the running position to the arrested position.
