Method and appliance for gluing laminated material involve press frame with top and bottom press plates, piston-cylinder units, intermediate plate, and locking appliances

摘要

A lifting and lowering appliance supported inside a press frame (2) presses the top, movable heated press plate(4) towards the bottom, fixed press plate (3). The lifting and lowering appliance for closing and opening the press-gap for lowering the top press plate until it comes into contact with the material (10) being compressed consists of several hydraulic closing and return piston-cylinder units 6,7). Short stroke piston-cylinder units (5) acting upon the top pressure plate and supported on a lowered and supported intermediate plate (9) build up pressure and compress the material. The intermediate plate is locked by means of several levered link and locking appliances in its bottom dead center position .
