A multi-layer laminating press including hot plates arranged over top of and movable in reference to each other, conveyers revolving around the hot plates, sealing elements that assist in forming vacuum chambers between each of a first hot plate and a respectively adjacent second hot plate arranged thereabove when the press is closed. The second conveyor lower run of the second hot plate rests on the first conveyor upper run of the first hot plate and the work piece to be laminated is arranged between the first conveyor upper run and the second conveyor lower run in the vacuum chamber. Connections are provided to pressurize and/or evacuate the vacuum chambers. The vacuum chambers are limited by either the first hot plate and the second conveyor lower run, or the second hot plate and the first conveyor upper run, without the interposition of another membrane for laminating the workpiece.
