Abstract
A pull-off aid of variable geometrical configuration for the overhead drawing-off of a thread (a,a') to be would onto a bobbin (1) from a feed or creel bobbin (11) mounted on a bobbin carrier, has an outer diameter which is variable by a control pulse which is dependent upon the increasing diameter of the bobbin (1) being wound and thereby upon the decreasing diameter of the feed or creel bobbin from which the thread is being drawn. To this end, a diameter sensor (2), by which the control pulse is initiated, responds when the bobbin being wound has reached a predetermined diameter.
