FIELD: production of nonwoven materials. SUBSTANCE: nonwoven fibrous materials is made with use of movable perforated member during realization of method of production of nonwoven fibrous material using frothed suspension. The first frothed suspension from air, water, fiber and surfactant is formed and supplied by centrifugal method, and brought in contact with movable perforated member. Foam, free essentially of fiber is withdrawn from perforated member during time of production of nonwoven fibrous material on perforated member, and at least one part of foam, free essentially of foam, is used for formation of the first frothed suspension. Recirculation is also performed using centrifugal pump. Centrifugal pumps are preferably used as degassing pumps for removal of some amount of gas and foam. It is possible to produce fibrous materials using frothed suspension with width in above 2 m at velocity of above 100 m/min (for instance, about 200-500 m/min). EFFECT: ensured practical increase of width of produced fibrous material and/or increase of its formation rate. 17 cl, 3 dwg, 1 tbl
