摘要
The invention pertains to a sliding surface for a continuously operating double-belt press for manufacturing endless material strips such as laminates, particularly copper laminate, decorative laminate, fiber-reinforced plastic laminates and/or other technical laminates, wherein the double-belt press comprises an upper and a lower endless press belt (04) that are guided over deflection rollers, wherein a reaction zone (13), in which the material strip is guided and pressed together under a surface pressure, is formed between the opposing outer sides of the press belts, wherein the double-belt press furthermore has a pressure chamber (08) that generates at least part of the surface pressure and is formed in the reaction zone (13) between a base element (07), particularly a heating plate, and an inner side (11) of the press belt (04), wherein said pressure chamber can be acted upon with a fluidic pressure medium and is laterally bounded and sealed by the at least one annular, closed sliding surface (01), wherein the sliding surface (01) has a sealing surface (12) for abutting on the inner side (11) of the press belt (04) in a sealing manner, wherein the sliding surface (01) comprises a sealing element (02) that forms the sealing surface (12) and a sealing frame (03) that at least partially accommodates the sealing element (02) and serves for movably supporting the sliding surface (01) in the base element (07), particularly in the heating plate, wherein a compression element (17) is arranged between the sealing frame (03) and the sealing element (02) at least in a pressing direction, and wherein said compression element allows a motion of the sealing element (02) relative to the sealing frame (03) due to an elastic compression, especially in reaction to a pressure application on the sliding surface (01) in the pressing direction.
