Abstract
A press for pressing a mat into a thin panel has a press frame, upper and lower press plates on the frame, upper and lower press belts having confronting lower and upper stretches defining a press gap extending in a horizontal and longitudinal transport direction and respectively running below and above the upper and lower press plates, respective arrays of rollers between each press plate and the respective stretch, and upper and lower flexible intake plates juxtaposed respectively above and below upstream ends of the lower and upper stretches of the belts and defining therewith an intake mouth flaring upstream. An array of spaced differential hydraulic actuators is braced between at least one of the intake plates and the frame and is operable to deform the one intake plate and thereby change the spacings of the belts at the mouth. A controller connected to the actuators can therefore steplessly change the shape and position of the belts at the mouth.
