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.
