ABSTRACT:
A method of spinning-in yarn on open-end spinning machines in which an interruption of the spinning process is followed by the stop of the feed of the sliver (4) into the singling-out device (2) whose combing roller (22) keeps turning, and the rotor is stopped at least during its cleaning. When the rotor (1) has re-started the yarn end is returned to it and brought into contact with the newly formed fiber band. Prior to the re-starting of the rotor (1) and at the latest simultaneously with the start of the feed device (3) of the sliver (4), the surface of the combing roller (22) is acted upon by a pressure air stream acting in the sense of rotation of the combing roller (22) between the place of supply of the sliver (4) to the combing roller (22) and the mouth of the fiber feed channel (212) to the rotor (1) so as to remove from the clothing (221) of the combing roller (22) fibers and sticking impurities. The invention also relates to a device for carrying out the method.
