ABSTRACT:
An adaptor is provided for an open-end rotor spinning arrangement, which adaptor is exchangeably arranged on a cover element of a spinning rotor and projects partly into the inside of the spinning rotor. The adaptor comprises the first section of a yarn withdrawal channel, as well as the end section of a fiber feed channel. On its side facing away from the spinning rotor, the adaptor has a bearing surface in the form of a plane ring surface, which by means of an axially effective fixing device is drawn against a take-up surface of the cover element. The circumferential surface of the adaptor is in the form of a cylindrical surface. A centering element, for fixing the adaptor on the take-up surface at an exact angle, is arranged at the fixing device, which centering element is disposed, in relation to the yarn withdrawal channel, almost diametrically opposite to the fixing device.
