Abstract

En fremgangsmåte for å fremstille papir på en papirmaskin omfattende å tilveiebringe en cellulosebasert, tynn råsuspensjon, å flokkulere suspensjonen ved å tilsette en vandig løsning av et polymert retensjons- hjelpemiddel valgt fra naturlig og syntetisk polymer og derved danne en flokkulert suspensjon, å forskyve den flokkulerte suspensjonen, å omflokkulere den forskjøvede suspensjonen ved å tilsette en vandig omflokkulerende suspensjon, å lede den omflokkulerte suspensjonen gjennom en ledning for å danne et flak, og å tørke flaket, karakterisert ved at stort sett fullstendig kokt stivelse tilsettes til suspensjonen etter forskyvningen og før ledingen.A method of making paper on a paper machine comprising providing a cellulose-based, thin raw suspension, to flocculate the suspension by adding an aqueous solution of a polymeric retention aid selected from natural and synthetic polymer, thereby forming a flocculated suspension, to displace the flocculated the suspension, to flocculate the staggered suspension by adding an aqueous flocculating suspension, passing the flocculated suspension through a conduit to form a flake, and drying the flake, characterized by adding substantially completely cooked starch to the suspension after the displacement and prior to the conduit. .
