Abstract
An opening roller for an open-end spinning device comprises a shaft supported in a bearing housing. A base body is arranged on the shaft, on which base body an exchangeable ring with combing structure is slidably arranged . The ring with combing structure is fixed at its end faces between a flange of the base body and a flange of a detachably applied tension disc. In order to brace the tension disc against the ring with combing structure by means of a spring element, a screw is axially screwed into the shaft, which screw is provided with working surfaces for a tool for pulling the opening roller out of a holding device of the bearing housing. The working surfaces are located at the end of a through bore hole of the screw on the side facing away from the head of the screw. The tension disc has an even outer front surface, which is partly formed by a covering cap, which comprises, in extension of the through bore hole, a small bore hole for inserting the tool.
