    Abstract: The invention relates to a method for producing paper, paperboard and cardboard, comprising the dehydration of a paper material comprising filler material, which contains at least one water-soluble polymer, forming sheets in the wire section and subsequent pressing of the paper in the press section, wherein the at least one water-soluble polymer is dosed to a paper material having a fiber concentration in the range of 20 to 40 g/l, the paper material is then thinned to a fiber concentration in the range of 5 to 15 g/l, the thinned paper material is dehydrated, forming a sheet, and the sheet is pressed in the press section to a solids content G(x) wt % or greater and G(x) is calculated according to G(x) = 48 + (x -15)·0.4, where x stands for the numerical value of the filler material content of the dry paper, paperboard or cardboard (in wt %) and G(x) stands for the numerical value of the minimum solids content (in wt %) on which the sheet is pressed, wherein the water-soluble polymer is obtainable via Hofmann reduction of a polymer comprising acrylamide and/or methacrylamide and optionally subsequent post-curing.
