A yarn-guide plate is movably seated in the area of the delivery tube holder, has a yarn guide notch as well as a yarn placement slit and can be selectively controlled by means of a thrust piston transmission device according to the purpose. By pivoting the yarn guide plate, the yarn extending through the yarn guide notch is transferred to a yarn catch device of a tube supporting disk seated in a bobbin frame. Subsequently, the grasped yarn slides automatically into the yarn placement slit which is disposed below the notch and, while being securely guided in the yarn placement slit, is wound as a reserve winding on the empty tube rotating in the bobbin frame.
