摘要:
Raw materials are portioned in a plurality of molds, which are continuously moved and transferred to a heating area by a conveyer. The heating area is divided into a plurality of sub-areas, each of which has power source means and power feeding means. The raw materials are heated and molded by applying high frequency to the molds from the power feeding means. Even if the heating apparatus is large, it is possible to restrain or prevent concentration of high-frequency energy since the heating area is divided into sub-areas.
