PROBLEM TO BE SOLVED: To efficiently do bending by a simple inexpensive apparatus. SOLUTION: In a bending method, a plate-like molding of a synthetic resin is bent into a prescribed curved profile. The continuously molded plate-like moldings are cut in turn. Each cut molding (cut board D1), in a plastic state in which the inside is soft and the surface is solidified, is piled up and pressurized. Each molding is bent into the prescribed curved profile. The cut moldings are piled up and bent at a time so that the bending can be done efficiently by the simple inexpensive apparatus. In this way, a production speed in a preceding process can be improved, and a cycle time can be curtailed. COPYRIGHT: (C)2005,JPO&NCIPI |
