ABSTRACT:
An end cap is releasably mounted on the end of a cylindrical hollow tube to form a reusable cylindrical yarn carrier or winding tube which carries a filamentary or fibrous yarn thereon. The end cap has a paper or wear resistant exterior surface and a rigid polymeric or metallic insert secured to and extending around the inner periphery thereof. The cylindrical hollow tube is formed of a cylindrical laminated paper outer surface and a rigid polymeric or metallic insert attached to the inner surface thereof adjacent at least one end. The rigid inserts carry threads that mate to releasably connect the end cap to the hollow tube. The abutting ends of the hollow tube and end cap, when assembled, define a peripheral starting groove therebetween. A minor portion of the peripheral groove is relatively narrow (locking portion), while the remaining major portion of the groove is wider (lead-in portion). When the yarn carrier has been emptied, the end cap is separated from the hollow tube and the residual fibers or filaments vacuumed or stripped away.
