Abstract
A method for producing a composite nonwoven in a continuous process sequence, and an apparatus for carrying out the method are provided. A fibrous web is formed by a carding device from a fiber strand, on the surface of which fibrous web subsequently a nonwoven layer of synthetic fibers is laid. To this end, the fibrous web is guided within a suction zone on a laydown belt to a melt-blowing device, in which the synthetic fibers are laid on the surface of the fibrous web by melt-blowing. The fibrous web which is covered with the nonwoven layer is subsequently laid by a nonwoven laying device in a plurality of layers to form the composite nonwoven.
