  • Patent number: 10414623
    Abstract: A method is provided for operating a textile machine, with a multiple number of adjacent work stations having a respective spinning unit with a spinning device and/or one winding device and handling elements for piecing a thread or for connecting two thread ends. If production is interrupted, a thread end on the bobbin side is provided to a defined receiving position at the work station. For piecing the thread or for connecting the thread ends, the thread end on the bobbin is cut to length by the work station work elements, received from the receiving position, prepared for piecing or for connecting and pieced up or connected. A thread end wound on the bobbin is sought out by means of a thread seeking device deliverable to multiple work stations of the textile machine, and the thread end is subsequently moved into the receiving position at the work station, from which it is received by the work station work element of the work station, in particular by a handling element of its own work station.

  • Patent number: 10400359
    Abstract: A method is provided for operating a textile machine having a plurality of work stations wherein, during normal operation of the work stations, a yarn is produced or is rewound from a delivery coil onto a receiver coil. The normal operation is initiated at the individual work stations after a stop of the textile machine, or is interrupted at certain time intervals by a service operation in the form of a piecing process, a tube changing process, or a yarn joining process. The service operations are divided into several partial sequences. A pending partial sequence for one of the service operations is carried out so long as energy resources required for carrying out the pending partial sequence are available independent of whether the energy resources for carrying out the other partial sequences for the service operation are available.

  • Patent number: 10351976
    Abstract: A method is provided for operating a spinning machine with a multiple number of spinning stations. In the normal case, the individual spinning stations are supplied with a fiber material and produce a yarn. Upon the occurrence of predefined events, yarn production is interrupted at individual or all spinning stations, whereas such spinning stations are, when required, subjected to piecing with the assistance of a piecing process in order to start up yarn production again. The respective piecing is carried out with the assistance of handling tools associated with the spinning machine. The individual spinning stations are classified on the basis of one or more production-related parameters, and that, if more piecing processes are to be carried out at the same time than can be carried out by the handling tools, at least the selection of the spinning station to be subjected to piecing next is carried out under consideration of the specified classification.

  • Publication number: 20190023522
    Abstract: A method at a workstation of a spinning machine or winding machine supplies an auxiliary thread from a thread nozzle to a suction assigned to the workstation, the auxiliary thread stretched between the thread nozzle and the suction. The auxiliary thread is severed to form a thread section protruding into the suction and a thread section extending into the thread nozzle, wherein the thread section protruding into the suction is carried away by the suction. The thread section extending into the thread nozzle is grasped with a thread receiver such that the thread section extending into the thread nozzle extends between the thread nozzle and the thread receiver. The thread section extending into the thread nozzle is severed to form a thread section remaining in the thread nozzle and a thread section coming from the thread receiver. The thread section coming from the thread receiver is transferred to the suction of the workstation.
