Abstract (en)

[origin: WO02084021A1] The aim of the invention is to provide a method and device with which the distribution of binders (2) and/or other additives in a nonwoven material layer (5) for the production of nonwovens can be homogenized. To this end, a binder (additive) gas flow (6) is blown onto and/or into a supplied nonwoven material layer (5) at high flow speed. Once the components of this mixture have interlaced to a certain extent, the mixture is deposited as a strip (7) on a transport device (4) and is then fed to a compaction station.
