Abstract:
A method for the production of ligneous material boards, comprising the steps of:curing a mat of material by the application of pressure and heat in a continuously operating hot press to form a board strand; after leaving the continuously operating press, dividing in a sawing apparatus the hot board strand into single boards of predetermined lengths; and then subjecting a plurality of the single boards to shock cooling while they are carried through a double-belt holding apparatus having holding belts that exert upon surfaces of the single boards a specific contact pressure of maximum 0.05 N/mm2, wherein backs of the holding belts are sprayed with coolant as they run, an active time of the shock cooling thus performed is continued until the temperature in the center of the single boards has reached approximately 80Â° Celsius to 100Â° Celsius.
