  • Patent number: 4794855
    Abstract: A continuous press machine includes a pressure applying device for urging a pair of opposed endless belts toward each other to compress a sheet-like material passing therebetween. The pressure applying device includes a stationary housing defining a pressure chamber and having a peripheral edge facing and spaced slightly from a back side surface of each endless belt, and a device for supplying a pressurized urging fluid to each of pressure chambers, so that the pressure in the pressure chamber is applied to the back side surface of each endless belt so as to urge each endless belt against the material. A seal device is provided for sealing a gap between the peripheral edge of each housing and the back side surface of each endless belt facing the peripheral edge, so as to prevent the pressurized urging fluid in the pressure chamber from flowing through the gap.

  • Patent number: 3988098
    Abstract: A process for continuously casting a sheet and the like, comprising, running two feed belts positioned in face-to-face relationship to each other, opposed belt surfaces of said belts being in the same direction without relatively displacement; running at least two gaskets together with the two belt surfaces at the both edges thereof; maintaining the opposed surfaces in any position rigid in the direction perpendicular to the running one and flexible in the running direction; supplying material between the belts from one side thereof; supporting the opposed belt surfaces by pressure of the material and retaining a gap in desired thicknesses between the belt surfaces in desired positions thereof; treating continuously the material between the belt surfaces and delivering treated sheet from the other side of the belts.
