METHOD AND APPARATUS FOR BENDING SYNTHETIC RESIN PLATE

摘要

PROBLEM TO BE SOLVED: To bend a synthetic resin plate by a non-heating method without generating blushing or crack by forming a waveform uneven shape on the elastically deformed plate, and fixing a predetermined mold corresponding to the previous shape to the deformed plate. SOLUTION: The synthetic resin plate bending apparatus 1 comprises a waveform shaping unit 3 for elastically deforming a synthetic resin plate 2 inserted substantially horizontally in a waveform shape, and a shaping unit 6 for fixing a predetermined mold to the deformed plate 2 delivered from the unit 3. The unit 3 has width deciding rollers 31R in contact with both ends of the plate 2, a first pressing roller 32A arranged laterally of the plate 2 at a surface side of the plate 2, and a second pressing roller 33A as a pair with the roller 32A at a position opposite to the roller 32A.
