Abstract

PURPOSE:To obtain a cylindrical body of a good quality useful for a wave guide, etc. by a method wherein a laminated tape installed with a thermoplastic synthetic resin layer on a plane of a metallic tape is formed into the cylindrical body by using a molding die having a gas flow hole for cooling, and after a protective coating is installed on the cylindrical body, the cylindrical body is cooled. CONSTITUTION:A molding die 46 having both end parts 41, 42 of an outer diameter almost as long as the inner diameter of the cylindrical body to be prepared, an intermediate part 43 having a diameter shorter than the inner diameter of the cylindrical body, and a gas flow hole 44 at the central part of the axial direction is prepared. Next thereto, a laminated tape installed with a thermoplastic synthetic resin layer on a plane of a metallic tape is formed into a cylindrical body so as to enclose the surface of a large diameter 41 part at the front end of the molding die 46, by using a molding device 4. Next thereto, a resin layer of the duplicated part of the laminated tape is heated by means of a welding device 6 to be welded, it is applied with an external pressure at a large diameter part 42 at the rear end of the molding die 46 and it is welded thereto, and further, it is cooled by passing the air into the gas flow hole 44, and along with this, the protective coating is pushed forward and the air is made to flow into the coated cylindrical body inside to prevent the shape of the cylindrical body from being made flat.
