A particleboard press for converting a thick mat into a thin panel has a frame, an upper beam and a lower beam carried on the frame and vertically confronting each another, respective upper and lower platens carried on the beams and vertically confronting each other, and respective upper and lower belts having stretches engaged under and over the upper and lower platens, respectively. The belts are synchronously driven so as to advance a mat in a transport direction through the press between the platens. One of the beams is vertically displaceable on the frame relative to the other beam and its platen has relative to the direction a downstream calibration portion and an upstream compression portion at least limitedly vertically displaceable relative to the one beam and the downstream calibration portion. The calibration portion is urged into a calibration position spaced a predetermined vertical distance from the other platen and the compression portion is urged with a predetermined generally constant force toward the other platen while permitting deflection of the compression portion of the one platen away from the other platen against this constant force and without substantial change of same. |
