Abstract

The present invention relates to a device for forming a reserve winding on a bobbin tube outside the traversing path of a main thread guide which moves to and fro along the bobbin tube wherein a thread holding device is disposed in the vicinity of a thread path between a thread delivery point and the bobbin tube. The device includes an auxiliary thread guide arranged in the region of the reserve winding between the bobbin tube and the thread holding device having two deflecting guides between which the thread can be guided parallel to the surface of the bobbin tube whereby a thread catching projection disposed on the bobbin tube and rotating therewith projects between the two deflecting guides for catching the thread, and a movable thread guide arranged on the side of the auxiliary guide away from the bobbin for transferring the thread to the main traversing thread guide after the reserve is formed.
