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.

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, including lateral border areas of the fiber layers, being 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. In the present apparatus for the execution of the method for the production of a non-woven fabric, one or more fiber feed rate control devices, each connected to a traverse drive unit, are arranged to one or more fiber flow transport devices, below an angle of 90.degree. to the transport direction of the non-woven fabric to be manufactured, and assigned to an already known non-woven fabric transport device. The fiber feed rate control device contains a rotation unit. The fiber feed rate control device is arranged at the beginning or above the non-woven fabric transport device. The traverse drive is formed as a pivot drive. In order to dissolve the fiber flow consisting of fibers, adhesively connected to one another, the fiber feed rate control arrangement contains a dissolving roll. The fiber feed rate control device and the traverse drive unit have variable speed motors for the required adjustment of the fiber flow feed rate to the delivery speed of the non-woven fabric, depending on the surface measurement of the non-woven fabric to be produced and the reinforcement speeds. The traverse drive unit has working width position stops.
