A separating apparatus mounted on the casing of a bobbin winding machine includes a pivotable separating support having upper leg on which separating flaps are swivellably attached. After the rotation of the revolver during a change of the bobbins, the support is pivoted and the separating flaps are moved to position portions of the flaps between the full bobbin and the newly supplied empty bobbin on which yarn is then being wound. In this position the separating flaps prevent the loose whizzing yarn end on the yarn on the still rotating full bobbin from coming into contact with the yarn package then in the process of being wound.

A thread winder includes a revolver on which two radially spaced mandrels are disposed for supporting thread-receiving tubes. Thread is wound onto one of the tubes located in a winding position and, when that tube is filled, the thread is transferred to the other, empty tube without interrupting the thread feed, by rotating the revolver. After the filled package is moved out of the winding position, a deflecting rod is swung to deflect the thread to a position where it can be grabbed by a transferring device. Then, the deflecting rod is swung away from the thread, and the transferring device is swung out to displace the thread toward a thread catcher disposed on the empty tube (or its mandrel), whereupon the thread is severed. A thread diverter is also swung out from the transferring device to shield the empty tube from the trailing end of the severed thread extending from the filled package.
