In a device forming a pressure cushion in a double belt press, the device including a pressure plate mounted in one support structure of the press, and a sealing member seated in a groove in the pressure plate to bear against the associated steel belt such that the sealing member, the steel belt and the surface of the plate surrounded by the groove together delimit a chamber arranged to contain a pressure medium to form the pressure cushion, the sealing member includes an elastically yieldable component extending around the entire path of the groove and arranged to be in sliding contact with the associated belt, and two wall components of rigid material each disposed along a respective lateral surface of the elastically yieldable component which extends transverse to the surface of the support plate and each located along at least one groove portion extending generally in the direction of belt advance, the pressure plate includes supporting elements defining at least part of the groove portions extending generally in the direction of belt advance and provided with a series of teeth projecting from the side thereof defining such part of the groove portions and spaced apart along the groove portions, and the sealing member has a toothed configuration along the sides thereof facing the supporting elements and formed to mesh with the teeth of the supporting elements for transmitting friction forces imposed on the sealing member by the associated belt to the pressure plate. |
