ABSTRACT:
When practicing a method and using an arrangement for producing a fibre layer or fibre mat from a liquid-absorbent material, e.g. in the manufacture of diapers, a fibre-air suspension is blown in between two endless, mutually parallel air-permeable conveyor belts (12,13) at a pressure which exceeds the pressure of the ambient surroundings. The conveyor belts form therebetween a forming space which is defined laterally by stationary or movable side-walls (18), the inner surfaces of which may be profiled so as to provide a fibre layer or a fibre mat with profiled side-edges.
