    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: The method in accordance with the invention serves the purpose of extracting a thread (1) by suction from a coil (3) and the re-attachment of a thread end (13) to a new thread (1), whereas the thread (1) is sucked in against its spooling direction through a suction nozzle (6) into an extraction system, a loop (14) is subsequently formed, the thread (1) is separated in the area of the loop (14), which discharges a thread end (13) in the extraction port and prepares the other thread end (13′) coming out of the coil (3) for re-attachment, and is subsequently attached to a new thread (1). Upon being extracted by suction, the thread (1) is guided through an eyelet (11) located in the run of the thread of the extraction port (8), the eyelet (11) is, together with the thread (1), moved out of the run of the thread of the extraction port (8), such that the thread (1) forms a loop (14) between the coil (3), the eyelet (11) and the extraction port (8), along with a corresponding device.

    摘要: A winding station of a textile machine for producing cross-wound bobbins includes a base unit, a cover unit, and a bobbin holder configured to hold the cross-wound bobbin. A traversing device is configured to lay a thread in a crosswise manner on the cross-wound bobbin. A thread finding device is configured to find a thread end on the cross-wound bobbin. The base unit at least partially covers the cover unit, and the cover unit is movable with respect to the base unit between a working position for laying the thread and seeking the thread end and a cleaning position for cleaning the winding station. At least portions of the thread finding device are configured on the cover unit. A method is also provided for operating the winding station.

    摘要: A textile machine and associated operational method are provided, wherein the textile machine has a plurality of workstations for (a) delivering a thread to a bobbin, (b) laying the thread on the bobbin, (c) winding the thread on the bobbin, and (d) finding a thread end wound on the bobbin with a suction nozzle. The thread is run through the suction nozzle during delivery to the bobbin such that the thread enters an inlet mouth in the suction nozzle and exits the suction nozzle through an extraction mouth. Starting from a thread delivery device at the workstation, the thread is run freely until the thread enters the inlet mouth of the suction nozzle directly in front of the bobbin. For finding of the thread end wound on the bobbin, the thread end is sucked into the suction nozzle through the extraction mouth.

    摘要: A system and associated operational method are provided to extract a thread by suction from a bobbin and for re-attachment of a thread end of the thread to a new thread. The thread is extracted from the bobbin by sucking the thread in against its spooling direction on the bobbin through a suction nozzle and into an extraction port of an extraction system. A loop is subsequently formed in the thread, and the thread is separated in the area of the loop. One thread end of the separated thread is discharged into an extraction port, and the other thread end coming from the bobbin is prepared for re-attachment to a new thread. Upon being extracted by suction into the extraction system, the thread is guided through an eyelet located in a run of the thread to the extraction port and the eyelet, together with the thread, is moved out of the run of the thread to the extraction port such that the thread forms the loop between the bobbin, the eyelet, and the extraction port.
