Abstract

The invention relates to a method for improving runnability of a wet paper web or the like. The method comprises adding to a stock of fibres a cationic polymer, forming a wet paper web from the stock of fibres, and applying an anionic polymer solution to the wet paper web. The invention relates also to a paper produced by using the method and to a use of a solution comprising an anionic polymer.
