摘要： A rotor spinning machine and associated method are provided for preparing a yarn end for spinning-in at a rotor spinning device, wherein the rotor spinning machine has a rotor housing that is closable with a cover and subjected to negative pressure through a negative pressure channel. A spinning rotor is rotatably mounted in the rotor housing and rotates with an operating rotational speed during a spinning operation. With the method, the yarn end is introduced into the negative pressure channel. The yarn end is then interrupted with a severing structure defined on an open edge of the rotating spinning rotor. During the interruption of the yarn end, the spinning rotor is driven with a defined rotational speed for the preparation of the yarn end that is equal to or less than an operating rotational speed of the spinning rotor.

摘要： A cleaning head (1) of a cleaning device (2) for cleaning a spinning rotor (3) featuring a fiber slide wall (4), a fiber collection groove (5) and an open edge (6) can, by means of a feed device of the cleaning device (2), be fed into a predetermined cleaning position (I) in the interior of the spinning rotor (3). The cleaning head (1) features at least one cleaning element formed as a scraper element (7), which is arranged on the cleaning head (1) in such a manner that, in the predetermined cleaning position (I) of the cleaning head (1), it is fed to the open edge (6) of the spinning rotor (3). A cleaning device (2) features a corresponding cleaning head (1) for cleaning a spinning rotor (3). With a method for cleaning a spinning rotor (3) by means of a cleaning device (2), which features such a cleaning head (1), after the feed of the cleaning head (1) into the cleaning position, the open edge (6) of the spinning rotor (3) is cleaned by means of a scraper element (7).

摘要： This invention relates to a thread guide unit (6) for drawing off a thread (4) from a rotor (2) of a spinning unit (1) of an open-end spinning machine with a draw-off tube (18) and a compressed air nozzle (21). In accordance with the invention, it is proposed that thread outlet element (19) is provided, a thread outlet element (19) is provided and a mouth (23) of the compressed air nozzle (21) is formed as a gap between the draw-off tube (18) and the thread outlet element (19). The invention also relates to an open-end spinning machine with a multiple number of spinning units (1), whereas each spinning unit (1) features a spinning assembly (3), a thread guide unit (6) in accordance with the preceding description, draw-off rollers (5), a spooling unit (9, 11) and a thread setting unit (15, 14, 16). The invention further relates to a method for operating a spinning unit (1) of an open-end spinning machine, whereas, if the thread (4) must be set, a thread setting unit (15, 14, 16) moves a thread end (17) to the thread guide unit (6), where the thread end (17) is initially fed into the thread guide unit (6) by a negative pressure prevailing in the spinning assembly (3) and is then sucked into the spinning assembly (3), whereas a compressed air flow, which emerges in particular from a compressed air nozzle (21) of the thread guide unit (6) supports the sucking in of the thread end (17) into the spinning assembly (3), in a manner synchronized with the setting of the thread (4).

摘要： A thread guide unit is used for drawing off a thread out of a rotor of a spinning unit of an open-end spinning machine. The thread guide unit includes a draw-off tube, and a compressed air nozzle configured with the draw-off tube. A thread outlet element extends into the draw-off tube. The compressed air nozzle includes a mouth formed as a gap between an inner diameter surface of the draw-off tube and the thread outlet element. A method for operating a spinning unit of an open-end spinning machine having the thread guide unit is also provided.

摘要： With a method for preparing a yarn end (9) for spinning in at a rotor spinning device (2) of a rotor spinning machine (1) with a rotor housing (3) that can be closed with a cover (4) and can be subjected to negative pressure through a negative pressure channel (8), with a spinning rotor (5) that is rotatably mounted in the rotor housing (3) and rotates with an operating rotational speed during the spinning operation along with a draw-off nozzle (7), the yarn end (9) to be prepared is introduced into the negative pressure channel (8), and is interrupted by a severing structure (10) of the open edge of the rotating spinning rotor (5), and is thereby prepared for spinning in. During the interruption of the yarn end (9), the spinning rotor (5) is driven with a defined rotational speed for the preparation of the yarn end, whereas the rotational speed for the preparation of the yarn end is either equal to the operating rotational speed of the spinning rotor (5) or is less than the operating rotational speed of the spinning rotor (5). A corresponding rotor spinning machine (1) features a control unit (17), by means of which the rotor spinning device (2) can be operated in accordance with one of the preceding claims.
