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.
