摘要： A process for cleaning an open-end spinning rotor which has a fiber collection channel and an open edge, which is covered by a rotor cover. A first compressed-air stream is directed towards the fiber collection channel in a first cleaning phase. Then, in a second cleaning phase, the spacing between the open edge of the spinning rotor and the rotor cover is increased. In addition, a suction air flow leaving the spinning rotor over its open edge is produced. To carry out this process, there is associated with the rotor cover an opening apparatus which is connected, together with at least one blower channel to a common control apparatus. Associated with the rotor cover and with the blower channel, are in each case two working positions, of which the respectively first working position is adopted during the normal spinning operation and in which a compressed-air stream which can be switched on to clean the spinning rotor and which leaves at least one blower channel directed towards the inner surface of the spinning rotor. The respective second working position is set so that the compressed-air stream leaving at least one blower channel either produces an air flow directed from the fiber collection channel towards the open edge of the spinning rotor or is guided away over the open edge of the spinning rotor.

摘要： In order to piece to an open-end friction spinning device with two friction spinning elements driven in the same direction and forming a nip subjected to suction, fibers fed into such nip are twisted into a fiber bundle. The fiber bundle is partially conveyed out of the nip in a longitudinal direction, grasped there, and then transferred to a winding device. An auxiliary conveying device is provided to convey the fiber bundle from a thread forming zone adjacent the spinning element nip up to the draw-off side end of such friction spinning elements. A grabber is provided to grasp the fiber bundle as it leaves such nip of the friction spinning elements and to transfer the forming thread to a draw-off device.

摘要： To stop and restart and open-end spinning machine with a plurality of spinning devices, all the spinning devices are stopped together, while the vacuum is maintained. The thread end resulting from this interruption in the spinning process is then prepared successively at each spinning unit for joining and is fed to the spinning device in a thread-joining position, whereupon the vacuum is then cut off. When the open-end spinning machine is started, after the vacuum has first been applied, the threads are fed together, on all the spinning devices to the fiber-collecting surfaces of the spinning devices. The open-end spinning machine has a service device movable along the machine for preparing the threads to be joined and for feeding them to the individual spinning cells, as well as a central control device which has a stoppig device and a starting device for the open-end spinning machine. The stopping device is connected in control terms to a switch-on device and to a switch-off device for the service device. By these means it is possible, when stopping the machine, to let it run by itself to prepare and feed the thread ends and to switch itself off.

摘要： In order to wind a newly joined thread onto a tube newly inserted on a spooling device on an open-end spinning mechanism, the newly joined thread, together with a thread portion containing a leader, is guided away before the start of the bobbin build-up. Thereupon, the thread portion containing the leader is severed from the thread, and subsequently, the thread supplied by the open-end spinning mechanism is transferred to the newly inserted tube. To exchange a full bobbin for a new tube, a thread break is produced, the open-end spinning mechanism is cleaned and the thread is thereupon joined anew. To carry out this process, there are, on an open-end spinning mechanism, provided with a thread-joining device and a spooling device, a thread-suction device (4), a thread feeder (42) transferring the thread (35) supplied to the thread-suction device (4) to a newly inserted tube, and a thread-severing device (41) assigned to the thread-suction device (4).

摘要： A method and system for maintaining spinning machines having a plurality of spinning stations include automatically positioning a maintenance unit proximate to the spinning stations for removing spinning components from the spinning stations and replacing the removed spinning components with replacement spinning components. The maintenance unit is configured to remove the spinning component from the spinning station for servicing, to immediately replace the removed spinning component with a replacement spinning component which is carried by the maintenance unit, and to transfer the removed spinning component to a remote service station. The removed spinning component is serviced at the service station and is subsequently picked up by the maintenance unit for subsequent installation into another spinning station.

摘要： To piece up to a spinning station consisting of two friction spinning elements (101) driven in the same direction and forming a nip, a thread 30 is conveyed to the nip so that said thread 30 reaches the thread forming zone (104) with its free thread end first. Feeding of the fibers into the nip is controlled so that the thread end (300) comes into contact with the fibers simultaneously with its reaching the thread forming zone (104). The friction spinning elements (101) are covered by a cover (130) which incorporates a fiber feeding channel (24). The cover, in addition to the fiber feeding channel (24), is equipped with a thread insertion slit (14) extending essentially in the longitudinal direction of the friction spinning elements (101). The thread insertion slit (14) extends from the outside of the cover (130) up to its inside, and from the end on the draw-off side up to the outlet end (240) on the side away from the drawoff. A thread holding device ( 7) which holds the thread (30) essentially parallel to the thread insertion slit (14) is installed outside the nip. The thread holding device (7) holds the thread (30) away from the nip, at the end of the friction spinning elements (101) closest to the draw-off for as long as the thread end (30) has not reached the nip.
