Abstract
A universal yarn carrier is disclosed which is adapted to have an advancing yarn effectively wound thereon, when used on either a P-wind or a Q-wind machine. The yarn carrier comprises a molded plastic tube having an external cylindrical surface, and at least one yarn catching means integrally formed on the exterior surface adjacent one end thereof. The yarn catching means is adapted to catch and anchor one or more of the initial yarn windings so as to prevent axial slippage thereof, and the yarn catching means comprises an annular depression, and an extension extending in the longitudinal direction across a portion of the depression so as to define a tip at the free end of the extension for engaging the yarn being wound upon the carrier.
