Abstract
A platen press, for the planar and parallel pressing of particle board and like materials comprises a press bed and a press plate, one of which is movable and is provided with a hydraulic system for developing the pressing force. A pair of spacer bars are provided on the press bed to flank the particle board and a set of bearing cylinders urges the movable press member to clamp the movable member against the spacers, thereby imparting a bend or distortion to the movable press member. According to the invention, this distortion is measured and the measured value is used to operate the main press cylinders to eliminate the distortion and ensure parallel compression of the particle-board mass.
