PURPOSE: To avoid careless mistake of combination of decorative sheets used on both sides when decoration is carried out on both sides of a molded product simultaneously with injection molding by a method wherein band like sheets of a same kind or different kinds are wound around a same roll (cylindrical tube) overlapping each other. CONSTITUTION: Before injection molding, a cavity 35 of an intermediate mold 30 is thoroughly covered by a first and a second decorative sheets 5A, 5B. An external appearance part from a part covering the cavity 35 in those first and second decorative sheets 5A, 5B and an outer peripheral part are respectively put between a fixed mold 10 and the intermediate mold 30 and between a movable mold 20 and the intermediate mold 30 to be held by restraining. Therefore, giving tension of a certain extent to the decorative sheet before injection molding in mold cramping or the like, or extracting by suction with evacuation of the decorative sheets 5A, 5B to the fixed mold 10 or the movable mold 20 side can be carried out. Then, the first and second decorative sheets 5A, 5B can be appropriately elongated before molding. |
