Abstract: front page image
(EN)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.
(FR)L'invention porte sur procédé d'amélioration de l'aptitude au passage sur machine d'une bande de papier humide ou autre. Le procédé comporte l'ajout d'un polymère cationique à une pâte de fibres, la formation d'une bande de papier humide à partir de la pâte de fibres et l'application d'une solution de polymère anionique sur la bande de papier humide. L'invention porte également sur un papier obtenu par ce procédé et sur l'utilisation d'une solution comportant un polymère anionique.
