Abstract (en)

[origin: WO2006045378A1] The invention relates to a method for supplying a fibrous suspension (S) to a headbox (1) of a paper or cardboard machine (2) or to a filter device. The fibrous suspension (S) can, for example, be formed by mixing a thick matter suspension (4) with a thinning liquid (5). Said method uses at least one degassing device (6), the action of said device corresponding to that of a centrifuge. The inventive method can be carried out in a compact manner and enables, for example, the use of large degassing containers to be omitted.
