ABSTRACT:
A yarn windup for generally cylindrical packages employing dual mode traverse that includes a first traverse device in the form of a reciprocable thread guide and a second traverse device in the form of a grooved roll to take over the traverse stroke near the ends of the traverse stroke of the reciprocating thread guide. The grooved roll is synchronously driven with the reciprocating traverse guide and the unique groove configuration coupled with appropriate yarn laydown on the grooved roller improves package formation.
