An exchangeable component of a textile machine with a surface coating or a treated surface within which color elements are embedded is provided. The color elements in the surrounding area of the coating or the treatment, upon radiation by a light of a first wave length or of a first spectral range of wave lengths, emit a light of a second predetermined wave length or a second predetermined spectral range of wave lengths. Furthermore, a detection apparatus is provided with a source of illumination for the radiation of such a component and for the detection of the emitted light.

Exchangeable component of a textile machine with a surface coating or surface treatment and a means for the detection thereof

For the design of an opening cylinder () for an open-end spinning device where the opening cylinder () has a face (), it is proposed that the base body () of the opening cylinder () be located on the end of a shaft () away from the bearing (), whereby an axial distance () exists between the base body () and the bearing (). To expose the gap () for maintenance purposes, the clothing holder () is designed so as to be removable in the axial direction across the bearing (), whereby the face () towards the bearing () is formed on the clothing holder ().

Opening cylinder for an open-end spinning device

A multicomponent opening roll for an open end spinning apparatus includes a core piece, upon which a holder for a tooth-set carrier is fastened. The tooth-set carrier (12) must be exchangeable as is determined by operational wear. In order that the axial width of the opening roll (1) is made independent of the axial width of the tooth-set carrier (12), the core piece (11) possess an axial detent (131) for the holder (13).
