Abstract

The invention relates to a fitting ring (27) for an opening roller (21) of an open-end spinning device (1), having teeth (38) which are formed by at least one groove (39) which is machined into the circumferential face of a basic body (45) and extends in the circumferential direction and by a multiplicity of indents (40) which are arranged substantially in the axial direction, wherein the separation spacing (t) of the teeth (38) which is predefined by the groove (39) is considerably smaller than the height (H) of the teeth (38). There is provision according to the invention for the teeth (38) to have tooth flanks (42) which are of concavely arched configuration continuously as far as into the groove (39).

Description

technical field The invention relates to a clothing ring for an opening roller of an open-end spinning device having the features stated in the preamble of claim 1 . Background technique Clothing rings for opening rollers of open-end spinning devices have been known for a long time in various embodiments and are described in numerous patent documents. This type of opening roller is used in particular to feed the fiber in the form of a spinning bobbin to the station of the open-end spinning machine before feeding the fiber strip into the high-speed rotating spinning device of the open-end spinning device. The belt is loosened into a single fiber. Such an opening roller, which rotates at a high rotational speed for this purpose, has on its circumference a tearing mechanism which combs the supplied fiber strip and in the process opens it into individual fibers. The opening rollers differ primarily in their method of production and also in the configuration of their tearing to...
