Abstract

The invention relates to an arrangement for feeding a fibrous suspension (1) to at least one headbox (8) of a paper or cardboard machine with at least one diluting device (5), in which the fibrous suspension (1) is produced by mixing a high-consistency suspension (6) with a diluting liquid, wherein the diluting liquid is formed at least in part by backwater (2) of the paper or cardboard machine, the backwater (2) is pre-degassed in at least one open channel (3) and subsequently is guided into a diluting device (5) via a degassing device (4). The expenditure is to be reduced thereby in that the potential energy of the fibrous suspension (1) in the channel (3) is not above the potential energy of the fibrous suspension (1) in the diluting device (5) and the pressure at the outflow of the degassing device (4) is between −0.3 and 1 bar or that the potential energy of the fibrous suspension (1) in the channel (3) is above the potential energy of the fibrous suspension (1) in the diluting device (5).
