Method of joining a thread of a take-up coil in a spinning rotor of a spinning station of a rotor spinning machine having a normal travel course therethrough from the spinning rotor to the take-up coil for a thread that has spun therein and having a thread draw-off device and a thread guide disposed in the normal travel course, the joining being effected by means of a traveling joining device having a thread draw-off device for drawing off a thread end from the take-up coil and having a thread delivery device for transfering the drawn-off thread end to the spinning rotor of the spinning station, the method includes the steps of guiding a thread back from the take-up coil to the spinning rotor through the thread draw-off device of the joining device, that has been switched to reverse operation, and through the thread draw-off device of the spinning station that has been switched to idling operation, switching the thread draw-off device of the joining device to forward operation at an instant at which the thread is joined, switching on the thread draw-off device of the spinning station at an instant at which the thread draw-off devices of both the spinning station and the joining device are operating in synchronism, removing the thread from the thread draw-off device of the joining device by means of the thread delivering device and transfering the thread thereby, at a winding speed of the take-up coil that is increased over the normal winding speed thereof, to the normal travel course of the thread and to the thread guide in the spinning station against the action of a restoring force and device for performing the method. |
