FIELD: process engineering.
SUBSTANCE: proposed method comprises the steps that follow. Making the multiple first layers (1a, 1b, 1c, 1d) of impregnated cellulose fibres. Making the multiple second layers (2a, 2b, 2c, 2d) of impregnated cellulose fibres. Making the wood chipboard (3). Making the set (4) of layers with top facing layer (4a) including first layers (1a, 1b, 1c. 1d) of cellulose fibres with central board (4b) abutting on top facing layer (4a) by its top surface (4b.1) including chipboard (3) and bottom facing layer (4c) abutting on bottom surface (4b.2) of central boars (4b) including second layers (2a, 2b, 2c, 2d) of cellulose fibres. Note here that top facing layer (4a) and/or bottom facing layer (4c) is made so that after escaping out of hot press (5) it features thickness of at least 2 mm. Displacement of said set (4) of layer in hot press (5). Pressing of said set (4) of layer in hot press (5) at increased pressing force and temperature for making multilayer board (6) and discharging said board (6) from hot press (5).
EFFECT: lower products costs.
