FIELD: pulp-and-paper industry. SUBSTANCE: method involves feeding aerosuspension onto movable forming grid inclined relative to aerosuspension flow; removing air component from aerosuspension by means of suction device positioned at reverse side of grid. Inclination angle α of forming grid in the direction of movement of grid in countercurrency to aerosuspension flow is selected from ratio arcctg (Vs/Vf+ ) <α <arcctg (Vs/Vf- ), where Vs is speed of forming grid; Vf is rate of filtering of air via layer of formed fabric and forming grid by means of suction device at set stationary air flow rate from aerosuspension into suction device; η is coefficient of filament sliding friction against forming grid. As a result, produced fabric is prevented from shifting under the action of aerodynamic pressure of aerosuspension flow. Method allows extent of homogeneity of produced paper to be increased. EFFECT: increased efficiency and improved quality of paper fabric. 1 dwg, 1 tbl
