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. When the yarn carrier has been emptied, the end cap is loosened from the hollow tube, and the residual fibers or filaments vacuumed or stripped away.
The hollow tube is formed from a shell of steel, aluminum, lightweight metallic alloys or a polymeric material reinforced with fibers of aramids, carbon, ceramics, glass, or hybrids thereof. The shell is of a prescribed length and a reduced wall thickness in the range of 0.062-0.200 inches. A cylindrical insert of another material is secured to the inner surface of the shell adjacent the marginal end portions thereof to receive the threaded end cap.
