A method in order to produce curved laminated sheets by glueing and pressing is technically simple and it is suitable to the production of for example curved laminated surfaces which have some part of them parallel to the direction of the pressing force. According to the invention the glueing procedure contains two clearly separate phases, both of them having separate structural parts in the mold system suited to their respective method. The first phase, bending of the layers (8) is performed by pressing layers with movable mold half (7) against the perforated sheet (12) which is a part of the stationary mold half (13). The second phase, the actual glueing, is made by pressurizing liquid or gas in the stationary mold half (13) which causes the thin membrane (11) on the perforated sheet to move against layers (8) to be glued and to press them against the movable mold half (7) according to the piece to be produced. |
