Abstract
PURPOSE:To reduce the difference of tension in the layer of wound-up thread between the inside and outside by providing both sides of a winding drum with taper collars thickened toward the center of this winding drum for reducing the change of tension at collar parts when the thread is let out. CONSTITUTION:Collars 2 and 2' of a bobbin are gradually thickened toward a winding drum 1 for shaping tapers. This construction permits to remove the change of tension when thread is let out to be supplied to a twisting machine, reduce the difference of tension in the layer of the wound-up thread between the inside and outside, simplify the work later on, and obtain products of higher quality.
