Abstract

PURPOSE: To readily obtain the pipes having different diameters, by forming open end sections of a folded sheet into an annular shape while the open end sections having a desired width are moved along a guide, so that the abutted ends are heated to be welded, and then the whole body is round shaped.
CONSTITUTION: The thermoplastic resin sheet 1 is folded and run with desired sections pinched between belt conveyors, and the disired width of the open end sections is moved along the guide to be gradually formed into an annular shape. The abutted ends are heated to weld by a heating member 40, then the welded ends are withdrawn from the guide and the whole body is round shaped.
