Abstract: A system for production of non-woven sheet material by the dry forming method, comprising a moving carrier web to receive a uniformly distributed layer of loose fibres and a fibre distributor unit located above and across the moving web. The distributor unit includes a closed conduit system for conducting a flow of air fluidized fibre material, this closed flow across the web being maintained by blowing action. The conduits located overhead the web are provided with outlet openings constituted by narrow slots or screen wall portion, and compressed air nozzles are arranged so as to cause fibres circulating in said flow crosswise to be moved crosswise in the flow outwardly through the outlet openings, whereby a high distributor capacity is obtained by simple means by forcing fibre material out of the outlet openings in a positive manner as distinguished from outlet by general suction from outside the outlet openings.

Abstract: A method and an apparatus for distributing loose fibres or particles onto a moving web in an even layer thereon preparatory to production of a non-woven sheet of the fibre or particle material. The material is filled into a container having a generally V-shaped screen bottom extending crosswise over the moving web, and whipping members are rotated in the bottom space so as to whip the material adjacent the interior surface of the screen by a whipping movement causing the fibres or particles to be slung against the screen and the material to move in a flow lengthwise along the bottom surfaces, whereby when suction is applied to the outside of the screen bottom through the web the fibres or particles will get dispensed through the screen and deposited on the web. The combined whipping and slinging of the material contributes to a high capacity of the distribution.
