Abstract (en)
[origin: US4665818A] In a double band press each of the press belts has an associated pressure chamber in which fluid pressure medium acts to pressurize the sheet form material passed between the press belts. Each pressure chamber is formed by a pressure plate, the associted press belt and a sliding surface seal mounted in a groove in the pressure plate with the seal in sliding contact with the press belt. The sliding surface seal is secured within a retaining member fitted with narrow play into a groove in the pressure plate. Each press belt extends horizontally between a pair of spaced rollers. The retaining member is vertically displaceable within the groove. Support members located within the pressure chamber secure the retaining member to the pressure plate. A groove seal in the form of an O-ring is located between the base of the groove and the retaining member and is in contact with the opposite sides of the groove. connecting passageways extend between the pressure chamber and the base of the groove so that the fluid pressure medium within the pressure chamber has access to the base of the groove.
