METHOD AND DEVICE FOR PRODUCING A SINGLE-LAYER OR MULTIPLE-LAYER FIBROUS WEB, AND SINGLE-LAYER OR MULTIPLE-LAYER FIBROUS WEB PRODUCED BY WAY OF IT

摘要

The present invention relates to a method for producing a single-layer or multiple-layer fibrous web (48), in particular a paper or cardboard web, comprising at least one fibrous material layer (28), wherein the method comprises at least the following steps: provision of at least one fibrous stock suspension (24) with a moisture content between 99.9 and 85.0% by weight in at least one storage vessel (12) or at least one feed line; direct feeding of the fibrous stock suspension (24) from the storage vessel (12) or the feed line to at least one fibrizing device (18) for fibrizing and/or for separating the fibrous stock suspension (24) to produce individual fibres and/or groups of fibres (42) and application of the individual fibres and/or groups of fibres (42) of the fibrous stock suspension (24) onto at least one permeable or non-permeable transport belt (26) in order to form the at least one fibrous material layer (28). Furthermore, the invention relates to a device for producing a multiple-layer fibrous web (10, 10'), in particular a paper or cardboard web.
