A device for applying surface pressure to a movable workpiece, for example a plate of wood, comprises two pressure-applying endless belts on which pressure is exerted by means of pressure air contained in two pressure chambers. Each pressure chamber is defined by a back side of the belt, a pressure plate and a sealing provided on the pressure plate. The sealing includes longitudinal wave-shaped sealing strips extended along the longitudinal edges of the pressure plate and transversal strips.
