Abstract
An opening roller for an open-end spinning arrangement is disclosed which contains a basic body pressed onto a shaft. This basic body contains an exchangeable ring mounting which is held by means of its end faces between a flange of the basic body and a tension disk. It is provided that the tension disk fitted onto the shaft is loaded in the axial direction by means of a screw which is screwed axially into the shaft and which, by means of the head, rests against the front face of the shaft. A spring element, preferably a cup spring, is arranged between the head of the screw and the tension disk.
