ABSTRACT:
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).
