PURPOSE: To improve productivity and manufacture a molding having no limit in the length thereof in principle, by a method wherein fibers and thermoplastic resin are carried into a compression molding unit by a belt to heat and mold them by the compression of a top force and a bottom force through said belt, thereafter, is compressed and cooled.
CONSTITUTION: Fibers, such as glass fibers or the like for example, is laminated on a thermoplastic resin film, such as nylon or the like, to obtain a molding material 20. These molding materials 20, mounted on a trestle 1, are supplied between upper and lower belts 2, 3. The belts 2, 3 are driven by a motor inch by inch and the molding material 20, sent to a preheating unit C, is heated by infrared rays heater or a far infrared rays heater, for example, to a temperature higher than the glass transition point of the molding material resin 20 or higher than the softening point of the same preferably. The preheated molding material 20 is sent into heating and compression molding molds 5, 6 of a compression molding unit D and is molded by compression effected by a hydraulic unit 9. Subsequently, the molding material is sent into compression and cooling molds 7, 8 to compress and cool it by the hydraulic unit 9.
