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 cylindrical hollow tube is formed predominantly of a cylindrical laminated paper tube. A rigid polymeric or metallic insert is attached to the tube adjacent at least one end. While the tube is predominantly paper, the interface between the hollow tube and the end cap is formed of a material that is rigid, incompressible, and capable of being threaded. The abutting rigid walls of the hollow tube and end cap, when assembled, define a starting groove there between. 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.
