Abstract
L'invention concerne un procédé de production d'un papier sur une machine à papier, comprenant les étapes consistant : a) à fournir une pâte, telle qu'un mélange de pâte de feuillus et de pâte de bois résineux ; b) à ajouter du polyacrylamide glyoxylé (G-PAM) cationique à la pâte à papier ; c) à former une bande à partir de la pâte dans une section de formation comprenant une caisse de tête ; d) à comprimer la bande dans une section de compression ; e) à sécher la bande dans une section de séchage ; et f) à éventuellement calandrer la bande dans une calandre.
