Abstract

L'invention concerne un procédé pour le collage en pile de papier, carton-pâte et carton, par adjonction continue et successive d'une dispersion aqueuse d'au moins une colle réactive et d'au moins un agent de rétention à un flux de pâte à papier à écoulement laminaire présentant une concentration de pâte d'au maximum 2 % en poids par rapport aux fibres sèches, et par égouttage de la pâte à papier pour former la feuille. Selon ce procédé, on dose la colle réactive et l'agent de rétention dans un écoulement turbulent en un point dans le flux de pâte à papier qui est situé après le dernier étage de cisaillement et avant le début du processus de déshydratation.
