A belt press has a plurality of upper and a plurality of lower traverses respectively having lower and upper traverse faces, upper and lower press platens carried on and between these traverses and having respective upper and lower platen faces respectively confronting the lower and upper traverse faces, and mechanically actuated bolts engaged between the traverses for displacing them toward each other and thereby pressing the platens against a belt engaged between them. The belt press also has at least one bend-compensating element having a pair of nonparallel upper and lower surfaces and engaged between one of the platen faces and the confronting traverse faces, and a hydraulic force transmitter engaged between this bend-compensating element and one of the respective press and platen faces. The transmitter is formed of a plurality of diametrally compressible but circumferentially unstretchable hydraulic hoses forming at least one substantially closed chamber of a predetermined maximum volume, and of a body of an incompressible fluid only partially filling this chamber. |
