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. A ring is slidably retained on the end cap in non-rotatably relation thereto between the adjacent end of the hollow tube and the confronting wall of the end cap. The confronting walls of the ring and end cap define a starting groove therebetween. A cavity of recess is formed, partially in the surface of each of the cap and ring, extending beneath and across the starting groove. When the yarn carrier has been emptied, the operator uses the cavity as access for scissors or a knife to sever the transfer tail and the major portion of the waste bunch. Later at a cleaning and refurbishing operation, the end cap is loosened from the hollow tube, and end cap and ring separated, and the remaining or residual fibers or filaments vacuumed or stripped away.
