<p>System for producing a cellulose web or sheet from an aqueous suspension of cellulose fibers, comprising a paper machine with at least one headbox (3) and one forming wire (5); a mixing section (15) for a slurry of cellulose fibers; a dilution section (17), wherein the slurry of cellulose fibers, coming from said mixing section (15), is diluted with water coming from the paper machine (2), to form the aqueous suspension of cellulose fibers; a fluid connection (23) from the dilution section (17) to the paper machine (2). The mixing section comprises a mixer (51) with a vertically extending tubular body, into which at least two feed pipes of flows of water and fibers and/or water and chemical additives lead tangentially. The flows entering the tubular body of the mixer are mixed and are fed to a machine tank (65) provided with a mechanical mixer.</p> |
