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： The present invention relates to a device for the conveying of fibers from an opener roller (31) installed in a fixed opener roller housing (30) to the collection surface (43) of a spinning rotor (4) of an open-end spinning device (1). It is provided with a rotor lid mounted on a swivel pin which receives a fiber feeding channel (6). The fiber feeding channel (6) can be brought into contact with a first contact surface (62) surrounding its inlet opening (60) against a second contact surface (35) located on the opener roller housing. It extends until directly in front of the collection surface of the spinning rotor (4). A lid extension extends through an opening in the spinning rotor (4) into the spinning rotor. In the lid extension the fiber feeding channel (6) lets out into the spinning rotor (4). The contact surfaces are essentially tangential to the circumferential surface of the opener roller and parallel to the opening of the spinning rotor or are inclined towards the opening of the spinning rotor.

摘要： With channels for the conveying of fibers, fiber slivers or yarns on spinning machines, problems are encountered in their manufacture. The channels must be made with a certain inside contour, where at the same time the quality of the surface inside the channel must be very good. The high surface quality is required in order to ensure trouble-free conveying. A channel is therefore proposed which is made as a tubular component, consisting of a metallic material and which has been produced by forming its interior by a medium under pressure. It is proposed for an open-end rotor spinning device to form the conveying channel separately from the other components of the lid of the rotor housing and to insert the channel into the lid. It is proposed in that case to use a channel according to the design shown above.

摘要： A device for the storage of a yarn of limited length spun on a spinning machine, comprising a suction pipe and a yarn storage chamber. The suction pipe is connected to a negative-pressure line and serves to seize the yarn by means of suction air. The yarn storage chamber is located between the negative pressure line and the suction pipe. The yarn can be aspirated into the yarn storage chamber and can be drawn off once more in the direction opposite to the direction of aspiration. The yarn storage chamber is located in a body which is rotatably mounted.In the process for the storing of the yarn, the yarn is seized by the stream of suction air and is sucked through the suction pipe into the yarn storage chamber. The yarn is accumulated against the screen surface of the yarn storage chamber until the stream of suction air in the suction pipe is weakened to a point where additional aspiration of more yarn is prevented. The yarn is then drawn out of the yarn storage chamber through the suction pipe in a direction opposite to the direction of yarn aspiration.

摘要： When a thread is joined in an open-end spinning device, the thread is fed back into the open-end spinning device as a result of reverse rotation of a bobbin and a pair of auxiliary rollers. After the feedback has ended, the thread is released by the pair of auxiliary rollers and, until normal spinning draw-off is started, the thread is subjected to an auxiliary draw-off at a greater distance from the open-end spinning device than the normal spinning draw-off. This auxiliary draw-off can be carried out exclusively by means of the bobbin or also independently of it. An auxiliary draw-off device serves for generating this drawing force and is located at a greater distance from the open-end spinning device than the pair of draw-off rollers.

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： 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).
