Abstract (en)
The method comprises pressing together two layers (34, 35) of multi-layered raw paper and wetting a layer of paper before pressing together with another layer, with a medium. A first medium is sprayed or fogged for wetting by a second medium. The spraying degree of the first medium is controlled over its throughput and/or over the pressure in second medium. The medium for wetting is suspension of a liquid-starch-mixture and the second medium is a gas. An independent claim is included for a device for the production of multi-layered raw paper.
