Press tools for lamination of two layers of material where at least one of the layers is porous and the bonding agent is an aqueous dispersion comprise at least one block (6,7,8) with passages (16) to inject a stream of dry gas at least via the mould face in contact with the porous layer. The adhesive may be applied to one of the layers, pref. (12) by spraying, coating, dipping or, pref. transfer roller. Pref. the press blocks and/or the air jets injected into the laminate are heated, opt. by local cartridge heaters. The press tool may both form and laminate component layers introduced as superimposed flat sheets.
