Abstract
A drive shaft is moved in a machine direction and a cross-machine direction to engage a spool on a winder. The drive shaft has an inner drive shaft which is elastically linked to an outer cylindrical shell, thereby allowing misalignment between the inner shaft and the outer shell and allows angular as well as horizontal and vertical displacement when the drive head engages the spool to provide centerwind assist to a roll of paper being formed thereon. The location of the drive shaft axis is determined at all times from geometric considerations and this data is used to position the drive shaft on the axis of the winding spool.
