Abstract
For disturbance-free insertion of threads (49a-49d) into a winding device (2) and for simultaneously taking over the threads on the bobbin tubes (5), the threads (49a-49d) are placed, using a suction gun (74), from the eyelets (70) (thread guides) provided at the apex of the traversing triangle, onto thread guide pins (51) mounted on a shiftable rail, which for the insertion into the winding device (2) is located at the free end of the bobbin chuck. Subsequently these guide pins (51) move the threads (49a-49d), as the rail (48) is shifted back, into such a position in front of the catching means (6), that the threads (49a-49d) are taken over by stationary, but pivotably arranged thread guides (41 or 79 respectively), from the guide pins 71, and are brought jointly, using a further pivoting movement, into the catching means (6).
