The invention relates to an apparatus for producing layers of dry fibres and/or particles on a forming surface pervious to air. According to the invention, the material is distributed in air and passed to a forming unit where a turbulence with high intensity is effected in that air is injected through separate nozzles.

Method for producing layers of dry fibres on a forming surface

A method of applying liquid in a finely divided form onto a moving surface and an apparatus for carrying out that method. A flow of air containing suspended liquid particles is passed substantially parallel to the moving surface and across its direction of movement within a container which extends across the width of the moving surface. The container has a slit or a series of openings facing the moving surface, through which slit or openings at least a part of the liquid particles entrained in the air flow are deflected and passed substantially normal to the surface to be deposited thereon.
