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.
