Abstract
Foreliggende oppfinnelse vedrører en fremgangsmåte samt en sammensetning for fremstilling av papir, hvorved fremgangsmåten for fremstilling av papir ved forming og awanning av en suspensjon av cellulose- holdige fibre og eventuelle fyllstoffer og kationisk stivelse på en wire eller duk omfatter forming og av- vanning i nærvær av et alkalimetallsilikat og en fenolharpiks tilsatt til suspensjonen ved samme punkt og polyetylenoksyd tilsatt til suspensjonen ved et påfølgende punkt.
