Abstract
An apparatus for producing a composite pipe having a desired wall thickness by using an endless steel belt as a mold which moves axially while rotating in the circumferential direction of a mandrel. In this apparatus, a thickness regulating device spaced a predetermined distance from the outside surface of the endless steel belt is used to adjust the wall thickness accurately to the desired value. Examples of the thickness regulating device are a cylinder roll, a taper roll, and a conveyor belt.
