Abstract

Den foreliggende oppfinnelsen vedrører en frem-gangsmåte til fremstilling av papp eller kartong hvilken ikke inneholder organisk fyllstoff. Fin-stoff fra bakvannssystemet og retensjonsmidler blir blandet og deretter matet til massen oppstrøms for papirmaskinen forut for blanding med den langfibre-de masse. Straks flokkulering finner sted, avvannes massen til dannelse av et ark som tørkes.
