Abstract

PURPOSE:To form a raw material into a desired shape without harming its transparency, by forming the raw material into the desired shape while clamping both of the outside surface part and the backside surface part, expected to be corner parts, of the raw material. CONSTITUTION:A softened raw material 1 is clamped between a male die 8, in which projections 13, 14, 15 acting as one group of coupled corner-forming projections, and a female die 9, in which the other projections 20, 21, 22 are formed, to form the raw material into a desired shape having a three-dimensionally curved surface. Since the vis-a-vis contact surfaces 13a-15a and 20a-22a of the coupled projections 13-15 and 20-22 are formed into concavity and convexity, respectively, the forming degree of the raw material 1 at the corners can be enhanced.
