Abstract
A tubular conduit for transporting a traveling texile yarn is formed of ordinary circular nylon tubing provided with a plurality of crimps formed at longitudinal spacings to provide interior projecting edge portions in the tubular conduit. The traveling yarn contacts the interior wall surface of the tubular conduit essentially only at the projecting edge portions to reduce frictional contact between the yarn and the tubular conduit to prevent yarn tension increases and yarn breakage.
