FIELD: woodworking industry. ^ SUBSTANCE: in the pressing device for continuous production of wood particle or fiber boards a chip or felt rug treated by an adhesive is subjected to a plane pressure between a circulating pressing band and a pressing drum. Means for setting the clearance of the required width between the pressing drum and the pressure roller, means for changing the feed of the material of the chip or felt drug, and a transducer for measuring the linear pressure are provided in the device. A cleaning unit first the pressing band over the entire width. The cleaning unit is positioned on a carrying track rotated with the aid of a drive transverse to the direction of motion of the pressing band. An the method for continuous production of chip or fiber layers, the chip or fiber layer with the adhesive is subjected to linear pressure between the pressing drum and the pressure roller for obtaining the required space density, and additionally subjected to plane pressure between the circulating band and the pressing drum, first the clearance of the required width between the pressing drum and the pressure roller is set, and then the linear pressure determining the space density is adjusted by changing the feed of the material of the chip or felt layer. ^ EFFECT: provided production of a wallboard of a high quality. ^ 70 cl, 3 dwg |
