Abstract
Abstract In a method for manufacturing a laminated plate material by compression forming, material (102) for lamination is sandwiched between two pressure plates (100), and a layer of fluid pressure medium is sandwiched between said material (102) for lamination and one of said pressure plates (100) and is pressurized so as to pressurize said material (102) for lamination. Thereby, the pressure is well distributed over the superficies of the material (102) for lamination, thus ensuring a good and uniform product. A device is also disclosed for performing the method.
