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 confronting ends of the hollow tube and end cap define a peripheral groove therebetween. A minor portion of the peripheral groove is relatively narrow (locking portion), while the remaining major portion of the groove is relatively 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.
