PURPOSE:To manufacture efficiently a decorative material superior in design, by a method wherein a fluid and nonfluid patterning materials are fed within a frame and the patterning materials are molded by heating them with a high- frequency and heating devices. CONSTITUTION:A fluid patterning material 3 of a powdery and granular body and a nonfluid patterning material 4 of a cylindrical or lumpy matter such as pasty or dry blended polyvinyl chloride are fed within a vessel formed of a frame 1 and bottom plate 2. The patterning materials 3, 4 are pressed with a press plate 5 and high-frequency wave W1 is generated by a high-frequency generator 6 through a metallic plate 7. With the high-frequency wave W1, the center part of the patterning material in the vessel is heated and at the same time heated like W2 by a heating device 8 such as Nichrome wire in the metallic plate 7 and a similar heating device 10 in a base body 9. Then at the same time, heating is performed like W3 with the frame heated by the whole of the device. |
