ABSTRACT:
A belt press is formed of a longitudinal row of upright and abutting press frames each comprising 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 the traverses and having respective upper and lower platen faces respectively confronting the lower and upper traverse faces, and mechanical actuators including bolts engaged between the traverses for displacing the traverses toward each other and thereby pressing the platens against a belt engaged therebetween with a pressure sufficient to deform the lower traverse. A lower bend-compensating element having a pair of nonparallel upper and lower surfaces is engaged between the lower platen face and the respective confronting traverse face. A hydraulic force-transmitter is engaged between the upper platen face and the lower traverse face. The bend-compensating element is shaped such that the lower platen remains planar and in direct contact through the bend-compensating element with the lower traverse.
