The invention is relative to opening devices for spinning machines, especially open-end spinning machines, that are provided with clothing wires or rings for separating fibers of a supplied sliver. The opening device is characterized in that the clothing wires are pre-bent in accordance with the geometry of a carrier ring, or the clothing rings have the desired geometry of the finished part, and that the particular workpiece surfaces have an at least two-coating construction in which an outer coating is a hard-substance coating. The hard-substance coating consists entirely or partially of especially hard hard-substance components and rests on a substrate layer located underneath it.

Opening device for spinning machines

A catalytically active object is produced by thermal spraying of platinum powder (54) together with a coating material (52) onto the object (18) during the formation of the outer layer of the object. In a preferred embodiment, the object is a godet of a synthetic filament processing machine, the coating material is an abrasion resistant ceramic and the platinum is exposed on the thread contacting surface of the godet to promote oxidation of deposits from the filaments being processed.
