Abstract
L'invention porte sur un procédé visant à ajuster les propriétés fibreuses de la pâte chimique, de la pâte mécanique ou de la pâte chimio-mécanique, ajuster le lissé et réduire toute variation de qualité. Selon ce procédé, on utilise, dans la fabrication de la pâte, un produit ligneux sélectionné en fonction du nombre des cernes de l'arbre. En fonction du nombre des cernes, on classe le produit ligneux en catégories qui représentent une certaine propriété de dimension des fibres telle que leur longueur ou leur grosseur. On classe le produit ligneux par grume ou groupe de grumes à n'importe quel stade de l'abattage du bois ou de la moisson de la plante ou à n'importe quel stade de la chaîne, entre la souche et la réduction en pâte et entre le défibrage ou le raffinage
