MANUFACTURE OF EXTRUDED MOLDING

PURPOSE:To contrive to reduce the cost of equipment and to improve operational property by bending the metallic foil after the outer surface of the foil has been coated with synthetic resin so as to form notches at the places corresponding to the groove provided on the metallic foil. CONSTITUTION:A metallic foil 1 is continuously drawn out of a foil developing machine, and fine grooves 11 are provided at the place where the metallic foil is to be bent along the longitudinal direction of the metallic foil by a fluting machine 2. Next, the metallic foil 1' is sent into the metallic die of an extruder 3 at the flat state as it is, and the onter surface of the metallic foil 1' is coated with a synthetic resin layer 5 in the die. Thus, the metallic foil 6 coated with resin is produced. The metallic foil 6 coated with resin has the notches 61 matching with the forming of a desired section at the place corresponding to the grooves 11. Next, the metallic foil 6 coated with resin is sent into a forming machine 4, and then synthetic resin 5 is welded integrally with said foil and is cooled at a desired section shape, while bending the foil at the notches 61. Thus, the extruded molding may be obtained.
