ABSTRACT:
The invention relates to a dual belt press for the continuous production of laminates with two heated, rotating endless belts running over rollers, the laminate being guided between the opposite outsides of said belts, with heating plates which, through annularly enclosed seals, contact the insides of the endless belts, and with a fluid, pressure-cushion-forming pressure medium in the spaces formed by the seals, belt insides and heating plates to exert the necessary pressing force on the laminate. To improve the transfer of heat from the heating plate to the reaction zone it is proposed that the spaces filled with the pressure cushion contain additional heat bridges which, in forming a good thermal conduction contact, are, on one side, connected to the heating plates and, on the other side, rubbingly contact the belt insides.
