Abstract

Clothing ring (27) for an opening roller (21) of an open-end spinning device (1), comprising teeth (38) which are formed by at least one groove (39) incorporated in the peripheral face of a basic body (45) and running in the peripheral direction, and a plurality of indents (40) arranged substantially in the axial direction. An axial separation spacing (t) of the teeth (38) is predetermined by the groove (39) and is significantly smaller than the height (H) of the teeth (38). The teeth (38) have tooth flanks (42) which are continuously concavely curved into the groove (39).
