Abstract

PURPOSE: To enable an integral forming of a large-sized item by molding under a vacuum double-layered sheet with specific molds and by providing a simultaneous highly accurate forming of thermal adhering of the sheet and of a hollow part.
CONSTITUTION: Overlapped two thermo-plastic resin sheets 3 and 3' are held between the molds 4 having the specified concave and covex portions and molded under a vacuum condition. The part to which the sheets 3, 3' are projected to form a hollow part therein is provided with a heater device 5 for softening the sheet in such a degree as a forming under a vacuum condition may be performed, and the part with which the sheets 3, 3' are integrally formed is provided with a heating device 6 for melting the sheets. The molds 4 are overlapped with each other and suctioned therefrom, a part facing toward the device 5 is formed with a hollow part 7, and a part facing toward the device 6 is formed with an integral portion thermally adhered under a pressurized condition.
