<p>PURPOSE:To permit an aluminum extruded shape to be formed easily even when the shape is provided with a complicated sectional configuration, by a method wherein a metallic foil, having a different material from the shape, is adhered to and laminated on the outer peripheral surface of the shape excluding mounting sections through a bonding film while both sides of the metallic foil are forced by a continuous rod into an engaging groove and are fixed together with the rod. CONSTITUTION:A laminated sheet 10 is arranged on a seat 11 so as to keep a bonding film 6 at the upper side of the laminated sheet 10 while an aluminum extruded shape 1 is put thereon so as to keep a mounting part 2 at the upper side thereof. Rotating rolls 12, 12 are moved along the outer peripheral surface of the aluminum extruded shape 1 while rotating them. The laminated sheet 10 is adhered to the aluminum extruded shape 1 along the outer peripheral surface thereof while applying a tension on the laminated sheet 10 widthwisely from the central part toward both sides thereof. Subsequently, both sides of the laminated sheet 10 are positioned on rod engaging grooves 3, 3 and rods 7, 7 are positioned on both sides of the laminated sheet 10 along the rod engaging grooves 3, 3, thereafter, both sides of the laminated sheet 10 are fixed to the inside of the rod engaging grooves 3, 3 by rod hammering machines 13, 13 together with the rods 7, 7. Then, the aluminum extruded shape 1 is heated to bond the metallic foil 5 to the shape 1 through the bonding film 6.</p> |
