Abstract: A method for automatically piecing a thread at a workstation of a textile machine, includes seeking an end of the thread on a surface of a bobbin with a suction nozzle and unwinding the thread from the bobbin counter to a regular draw-off direction of the thread and sucking the thread into the suction nozzle. The bobbin is driven in a direction of reverse rotation with a drive. A thread loop is draw-opened in the thread and moved towards a piecing unit via movement of a feeder unit. The bobbin is driven in the direction of reverse rotation during the drawing-open of the thread loop such that the thread is unwound from the bobbin. A speed of reverse rotation of the bobbin is coordinated with movement of the feeder unit.

Abstract: 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.
