ABSTRACT:
A method for the continuous production of foam materials, wherein the foaming and/or foamed synthetic starting material is passed through the pressure zone (4) of a continuously operating press (1), and in which method at least a part of the heat required for foaming is produced in the synthetic starting material itself as dielectric heat of an electromagnetic high-frequency condenser field, wherein production of this heat in the starting material takes place at least to its greatest part within a high-frequency condenser field which is arranged in the direction of passage (8) of the material through the press (1) in front of the pressure zone (4), and that in order to supply additional heat into the foaming and/or foamed starting material or in order to prevent or delay its surface cooling, at least one of the electrodes (10, 11) between which prevails the high-frequency field and/or at least one of the pressure surfaces of the press may be heated.
