CA 2360223

A method in connection with the manufacturing of paper or cardboard in one or more plies in order to achieve a paper or cardboard product with an even and high quality, whereby a fibre composition of a paper or cardboard waste, so-called broke (7), is determined (4), whereafter the said broke is fractionated (5, 6) and at least one fibre fraction (8, 9, 10) obtained thereby is conveyed to a given ply in the paper or cardboard, whereby the said fractioning (5, 6) is controlled so that the fibre composition in the fibre fraction (8, 9, 10) obtained is adapted to a fibre composition in the input paper pulp (1, 2, 3) for the said given ply.

L'invention concerne un procédé associé à la fabrication de papier ou de carton selon un ou plusieurs jets de manière à obtenir un produit en papier ou carton de qualité. On détermine (4) une composition fibreuse d'un reste de papier ou de carton, communément appelé rejet (7), qui est ensuite fractionnée (5, 6). Au moins une fraction fibreuse (8, 9, 10) ainsi obtenue est transportée vers un jet donné du papier ou du carton. Cette opération (5, 6) est commandée de manière que la composition fibreuse dans la fraction fibreuse (8, 9, 10) obtenue soit adaptée à une composition fibreuse dans la pâte à papier d'entrée (1, 2, 3) pour le jet donné.
