An end cap (20) is releasably mounted on the end of a cylindrical hollow tube (10) to form a reusable cylindrical yarn carrier or winding tube which carries a filamentary or fibrous yarn thereon. The confronting walls (16, 30) of the hollow tube and end cap are formed of a rigid material and define a starting groove (40, 42) therebetween. When the yarn carrier has been emptied, the end cap is loosened or separated from the hollow tube and the residual fibers or filaments vacuumed or stripped away. |
