Abstract (en)
[origin: WO2012052535A1] The invention relates to a method for producing a composite nonwoven in a continuous process sequence, and to an apparatus for carrying out the method. Here, a fibrous web is formed by a carding device from a fibre strand, on the surface of which fibrous web subsequently a nonwoven layer of synthetic fibres 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 fibres 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.
