PROCESS FOR MANUFACTURING PARTICLE BOARDS AND SIMILAR, AND SUITABLE TWIN-BELT PRESSES

摘要

In a twin-belt press or similar, the pressure on the mat (10) entering the machine is increased rapidly, once the latter comes in contact with the heat-transmitting surfaces (1, 2), so that the high pressure causes the outer regions of the mat to harden before the heat penetrates to the interior of the mat (10). The quality of the surface of the board (P) is thereby enhanced. For this purpose, a nip (17) for example can be provided before the run-in gap (13).
