Abstract
An opening roller for an open-end spinning arrangement is provided with a combing ring, which is slidably mounted onto a base body and is supported between two clamping surfaces. In order to fix the combing ring radially to a cylindrical guiding surface of the base body, the combing ring is provided with a centering surface on its inner circumferential surface. The combing ring has stopping surfaces on its end sides, which are arranged to engage the clamping surfaces. The centering surface is limited to an end area of the inner circumferential surface. The part of the inner circumferential surface of the combing ring which is located outside of this end area is free from counter-surfaces of the base body. As a result of this arrangement, the seat-engaging surfaces are on the one hand very short, while on the other hand various embodiments of combing rings can be used.
