ABSTRACT:
A side disc (2) for axial introduction onto a support disc (1) for a support disc bearing of the rotor of an open-ended rotor spinning machine having at least one reflecting region on the side of the side disc (2) facing a light source which is being otherwise substantially non-reflecting, wherein the reflecting region in the side disc (2) has one or more reflectors (3) worked into the side disc, is characterized in that the side disc (2) is made from injection moulded transparent and preferentially colourless plastic, and the reflectors (3) are fashioned on the side of the side disc (2) facing away from the light source in a form of cats-eye structures, and the region of the formed reflectors (3) is stepped-back with respect to other portions of the side of the side disc (2) facing away from the light source, and a fitted member (5) is provided for which is mounted into a recess (6) of the side disc (2) containing the reflector (3) and which completely covers, in a dust-tight manner, the region of the corresponding reflector (3) on the side of the side disc (2) facing away from the light source. In this fashion, the required exchange of the side or support disc resulting from decreasing reflectivity of the reflector is avoided.
