Abstract

The method comprises dispersing fibres in a gas stream to obtain a gas/fibre stream, supplying the gas/fibre stream on to a flat screen, removing gas from the gas/fibre stream through said screen to form a fibrous layer thereon, and subsequently treating the layer to obtain a fibrous sheet material, wherein a part of the gas is removed from the gas/fibre stream prior to supplying it on to the flat screen, so as to bring the fibre concentration up to 20 to 500 g/m<3>. The concentration is chosen in accordance with the kind and properties of fibres. Simultaneously transversal pulsations induced in the gas/fibre stream in the course of its movement are damped. The apparatus comprises a slot nozzle 3 having parallel side walls 9, 10 which are normal to converging frontal walls 11, 12, its inlet opening being connected with a means for dispersing fibrous in a gas stream, while its outlet opening is connected with a chamber 4, a flat screen 5 which collects a fibrous layer is mounted under said chamber, and a suction box 6 is arranged underneath the flat screen, a means 13 for removing a part of gas from the gas/fibre stream is arranged in the chamber under the outlet opening of the slot nozzle, and the chamber is provided with branch pipes 15 for gas exhaust, mounted in the upper portion of the chamber. <IMAGE>
