摘要
The invention relates to a sliding surface seal for a continuously operating double belt press for the production of endless material webs, such as laminates, in particular copper laminate, decorative laminate, fiber-reinforced plastic laminates and / or other technical laminates, with an upper and a lower endless press belt (04) guided over deflection drums, wherein a reaction zone (13) is formed between the mutually opposite outer sides of the press belts, in which the material web is guided and pressed under a surface pressure, with an at least partially pressure chamber (08) which generates the surface pressure and which is located between a base element (07), in particular one Heating plate, and an inside (11) of the press belt (04) is formed in the reaction zone (13), which can be acted upon by a fluid pressure medium and is laterally limited and sealed by the at least one annular, self-contained sliding surface seal (01), whereby the The sliding surface seal (01) has a sealing surface (12) for sealing contact on the inside (11) of the press belt (04) and the sliding surface seal (01) has a sealing element (02) that forms the sealing surface (12) and at least partially the sealing element (02) Receiving sealing frame (03) for the movable mounting of the sliding surface seal (01) in the base element (07), in particular in the heating plate, wherein a compression element (17) is arranged between the sealing frame (03) and the sealing element (02) at least in one pressing direction, which enables a relative movement of the sealing element (02) with respect to the sealing frame (03) by means of an elastic compression, in particular in response to pressure being applied to the sliding surface seal (01) in the pressing direction.
