Abstract (en)

[origin: EP1435281A1] The continuous belt press, for the production of wood boards, has upper and lower frame sections (7,8) and continuous steel belts (9,10) to draw the wood material mat (4) through the press (3). The steel belts are supported by roller rods (16) at the heated plates (12,14). The length of the press zone is at most11 m, the entry zone has a length of 1.3-1.7 m, and there is a joint at the upper frame section. The upper heated plate (14) is expanded after being in contact with the wood mat for 1.8-2.4 m, to give an abrupt pressure release (11) at the press gap (23) for a heated plate thickness of 90-100 mm, with flexible rolling plates (15) at the roller rods.
