Abstract: For the design of an opening cylinder (1) for an open-end spinning device where the opening cylinder (1) has a face (11), it is proposed that the base body (12) of the opening cylinder (1) be located on the end of a shaft (2) away from the bearing (21), whereby an axial distance (9) exists between the base body (12) and the bearing (21). To expose the gap (22) for maintenance purposes, the clothing holder (3) is designed so as to be removable in the axial direction across the bearing (21), whereby the face (11) towards the bearing (21) is formed on the clothing holder (3).

Abstract: 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).

Abstract: For an opener roller for an open-end spinning device provided with a basic body by which it is connected to a supported shaft for rotatable support, it is proposed that the clothing be attached to the basic body via a clothing holder, whereby fasteners are used. For the fixed allocation of the clothing holder to the basic body it is provided that the attachment of the clothing holder by means of the fasteners be effected from the side of the opener roller which is facing the shaft bearing. The face of the opener roller away from the shaft covers the shaft, so that this face of the opener roller is also an even surface.
