Environment purifying material

In order to apply pressure and heat to a sheet material as required in the manufacture of a laminated sheet material, the sheet material is conveyed in through an entrance opening of a pressure vessel, along through an interior space thereof, and out through an exit opening thereof, substantially filled with a pressure medium which is maintained at a temperature above its melting point in the interior space of the pressure vessel, but is maintained at a temperature below its melting point in the entrance and exit openings of the pressure vessel, so as to accomplish sealing in such zones by solidification of the pressure medium, whereby enabling continuously to treat a long sheet material under constant application of pressure and heat over a relatively long time period in which respective portions of the sheet material traverse the pressure vessel.

Method for pressure lamination utilizing fluid medium with partial

A method for manufacturing a laminated plate material by compression forming, in which material for lamination is sandwiched between two pressure plates, and a layer of fluid pressure medium is sandwiched between said material for lamination and one of said pressure plates and is pressurized so as to pressurize said material for lamination. Thereby, the pressure is well distributed over the superficies of the material for lamination, thus ensuring a good and uniform product. A device is also disclosed for performing the method.
