Beschreibung
Zusammenfassung:	A method for the production of a continuous nonwoven fabric from fiber mixtures of carrier fibers and binding fibers, comprising the steps: a. Feeding fibers; b. Breaking up, combing and opening out the fibers; c. Mixing the fibers; d. Sucking the fibers between two opposing airpermeable conveyor belts running at identical speed, such that the air is sucked from the outside in the front section of the conveyor belts in such a way that the air flow is always sucked through the deposited nonwoven fabric by air extraction at different times and different locations across the width and parallel to the conveyor belts and the fibers are thereby positioned perpendicular to the surface of the conveyor belts; e. Thermally solidifying the nonwoven fabric created by heating with hot air or shortwave radiation and cooling. Also a nonwoven fabric production apparatus.
