Abstract: A method and apparatus for forming a corrugated tube having a smooth inner wall surface and a corrugated outer wall are provided. A first strip of resin material is wrapped around first portions of rollers arranged in a circular array and is helically wrapped around the first portions of the rollers each having equally spaced ridges therearound to form the corrugated outer wall. A second strip of resin material is fed from the interior of second portions of rollers arranged in a circular array onto the inner surface of the outer wall being manufactured and bonded thereto. The second strip bonded to the outer wall is wrapped around the second portions of the rollers each having a smooth surface to form the smooth inner wall.
