Abstract

PURPOSE: To mold a front cover material neatly at a high efficiency by applying high frequency heating thereto while the whole peripheral rim including not only the side rims but also corner ends of a sheet material is inverted inwardly over the base material.
CONSTITUTION: A concave part is provided on the top of the table 17 and a front sheet 2 such as vinyl broader than the concave part is arranged across the part. Then, it is superlaid with a cardboard core 4 made smaller by the thickness of the sheet than the concave part while coated at least on the top periphery thereof with a vinyl resin and erected on the periphery 2'. On the other hand, an upper electrode 3 having four L-shaped sectional frame rims 31 is supported suspended above the sheet with a support disc 5 having a press surface 53. The frame rims 31 are moved so that the lower end thereof is positioned close to the top of the frame side plate 17'. In this manner, the sheet is made movable radially. A high frequency heating is applied to the sheet while the erected periphery 2' thereof is inwardly inverted.
