ABSTRACT:
In an apparatus for forming a thread-reserve winding, with a bobbin plate (4) which rotates together with the bobbin tube (3) and which engages by means of a centering shoulder into the inside diameter of the bobbin tube and has a thread-catching device, there are arranged on the periphery of the bobbin plate (4) slits (40) which extend in a radial direction up to the inner centering shoulder. The slits (40) can be made straight or arcuate and, to guarantee that the thread is caught particularly securely, form their entrance at an acute angle with the tangent to the periphery of the bobbin plate (4). To bring the thread into a position favorable for catching it, two thread guide elements (7, 8) can be moved into the thread path extending from a thread draw-off pipe (1) to a thread-suction device (6). These feed the thread to the thread-catching device approximately parallel to the tube axis.
