ABSTRACT:
Apparatus for embossing preformed particle board retains the board in a desired position after insertion between a first and a second press plate (4;3) in a press and releases after pressing the board from the press plates. The product (7) is sucked tight against the first press plate (4) after being placed in a desired position in the press. The suction process takes place either directly or via an intermediate permeable means (12; 14) and is so adjusted that it will be sufficient to stip off the board from the second press plate (3). Subsequently, the suction force may be replaced by a pressure force, for releasing the board (7) from the first press plate (4) or the intermediate means (12; 14).
