ABSTRACT:
In a yarn cross-winding apparatus of the type wherein a driven winding drum peripherally drives a bobbin and a traversing yarn guide applies yarn in a cross-wound fashion to the bobbin periphery, the problem of increased yarn winding density at the opposite ends of the bobbin is avoided by forming opposite peripheral end areas of the winding drum, whereat cross-winding yarn reversal occurs, with oppositely angled intersecting grooves forming a plurality of relatively staggered yarn engagement locations over the circumferential and axial extent of the peripheral end areas of the drum. The yarn engagement locations guide the yarn onto the bobbin at its opposite ends to resist deviation of the yarn from its cross-winding angle at the location of yarn cross-winding reversal.
