Abstract

PURPOSE:To easily obtain a cylinder wall excellent in strength at its bent part, gas shielding-property and light shading-property, by heating a synthetic resin laminate cylinder provided with an aluminum foil layer, and forming the cylinder into a core shape. CONSTITUTION:A cylinder piece 5 composed of a thermosetting synthetic resin is extruded from an extrusion die 1. The cylinder piece 5 is inserted and settled in an assembly drum 2. A transfer sheet 13, which is prepared by laminating a laminate sheet 8, comprising an aluminum foil 9 coated with a synthetic resin layer 10 at its outside, through a stripping layer onto a base sheet 12, is pressed onto the cylinder piece 5 by a hot-press roller 3 in a manner such that the laminate sheet 8 is positioned at the side of the cylinder piece 5, to transfer and weld the laminate sheet 8 onto the periphery of the cylinder piece 5. Thus, a cylinder body 6 is formed. The cylinder body 6 is heated to a proper forming temperature, and telescoped onto a polygonal core 4 to obtain a desired cylinder wall 7.
