Abstract
A traveler for use on vertical textile yarn spinning or twisting rings. The traveler comprises two parts. A ring contacting part bears against the spinning ring as the traveler travels around the ring and a yarn contacting part engages the yarn as it passes from the feed rolls to the bobbin on which the spun yarn is wound. The ring contacting part is joined to the heat-conductive, yarn contacting part so that a substantial portion of its surface is exposed to the atmosphere. As the traveler spins around the ring, heat generated in the area where the yarn frictionally engages the yarn contacting part is conducted away from this area and is dissipated into the atmosphere due to the motion of the air past the exposed surface of the yarn contacting part. The yarn contacting area is thereby cooled.
