ABSTRACT:
A press for pressing a mat into a thin panel has a press frame, upper and lower press plates on the frame, and 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. Upper and lower flexible intake plates are juxtaposed respectively above and below upstream ends of the lower and upper stretches of the belts and define therewith a downstream portion of an intake mouth flaring upstream. Upper and lower rollers are respectively braced against the upper and lower stretches of the belts at an upstream portion of the intake mouth immediately upstream of the downstream portion of the intake mouth. Further actuators connected to the rollers set a shape of the upstream portion of the intake mouth.
