HEATING DEVICE FOR PLASTIC SHEET

摘要

PURPOSE:To obtain the titled device capable of supplying a heated plastic sheet quickly to the forming process without lowering its temperature by equipping a high-speed lift on the side of the outlet of a conveyor device. CONSTITUTION:A plastic sheet A on a main conveyor device 16 is heated by a heating furnace 10. When it arrives at the softening temperature and comes near the outlet opening part 20, an air cylinder 34a is driven to lift a subsidary conveyor device 32a and move a plastic sheet B after heating. The subsidiary conveyor device 32a moves the sheet B at a high speed outside the furnace. When the sheet reaches a stopper 36a it is moved again to the conveyor device 16 and supplied to a compreession molding machine.
