摘要:
A non-woven fabric is produced by the transportation of a fiber flow at an angle which is less than 90.degree. to the transport direction of the non-woven fabric to be manufactured, with the feed rate of the fiber flow being controlled, the fibers which are to form a fiber layer being placed next to one another, and with the formed fiber layer being simultaneously, and in the lateral border areas of the fiber layers, being consecutively, combined with the preceding fiber layer, reinforcing the produced non-woven fabric. The angle of the fiber flow to the transport direction of the non-woven fabric to be manufactured is set between 0.degree. and 89.degree.. The controlling of the fiber flow comprises monitoring of the quantity feed rate and/or dissociation of the fiber flow and/or fiber mixing, immediately prior to the formation of a fiber layer. In order to combine the formed fiber layer with the preceding fiber layer, this is placed adjacent to the formed fiber layer, or placed on at least one formed fiber layer.
