Abstract (en)

[origin: EP3354431A1] The invention discloses a method for pressing fiberboard. A to-be-pressed fiber mat is sent into a feeding area formed between a top steel belt and a bottom steel belt along with circulation of the top and bottom steel belts and then into a pressing passage formed between a top feed heating plate and a bottom feed heating plate to be pressed into the fiberboard. The pressing passage is divided into a normal pressing curing zone and a pressing but not curing zone, and the to-be-pressed fiber mat enters the pressing but not curing zone first and then enters the normal pressing curing zone. When the to-be-pressed fiber mat is pressed but not cured, the thickness of the to-be-pressed fiber mat is compressed, but the adhesive is not cured. The invention further discloses a continuous press adopting the above method. The thickness of precuring layers on the top and bottom surfaces of the obtained fiberboard is greatly reduced, raw materials are saved, the sanding quantity and power consumption of the sanding machine are reduced, and sanding dust is also reduced.
