ABSTRACT:
A supporting ring for a supporting ring bearing of the rotor of an open end rotor spinning machine for the optical control of a joining carriage and having at least one reflecting region on an otherwise substantially non-reflecting axial ring surface (2) of the supporting ring (1) facing a light source, wherein one or more cupped receptacles (6) are provided for in the ring surface (2) into which reflectors (3) can be inserted and secured, and wherein an interruption of a rotational motion of the supporting ring (1) about a rotational axis (4a) is optically recognized by the joining carriage to start a joining carriage execution procedure, is characterized in that the depth of a receptacle (6) is larger than the thickness of a reflector (3) which can be placed therein. In this fashion the disadvantages of conventional supporting rings having reflectors can be avoided and optimal reflection can easily be restored at any time after wear of individual reflectors.
