Abstract
An improved fixture and related method are provided for making spiral wound hose from elongated strips of thermoplastic material. The fixture includes feed rollers for spirally winding inner and outer interlocking strips from opposite directions onto a rotating mandrel. As the strips are wound together, a laser integrally fuses the strips to each other along a continuous line of contact to form an elongated hose. Rotating channeled guide rollers are spaced circumferentially about the mandrel to advance the formed hose continuously off the mandrel.
