A disk (28) especially suitable for a papermaking wood chip and pulp refiner (20) has an array of refiner bars (50) which protrude outwardly from a base member (52). Grooves (56, 60) are formed between adjacent bars (50) which may change in depth toward the outer diameter (33) of the disk (28). Alternating grooves (56, 60) are of greater depth, to increase the open area of the disk (28) to facilitate steam evacuation without significantly reducing the bar stiffness and hence resistance to breakage and deflection of individual bars (50).

Un disque (28) qui convient particulièrement à un raffineur (20) de copeaux de bois et de pâte à papier pour papeterie comporte un ensemble de barres de raffinage (50) qui se prolongent vers l'extérieur d'un membre de base (52). Des rainures (56, 60) sont formées entre les barres adjacentes (50) qui peuvent varier en profondeur vers le diamètre extérieur (33) du disque (28). Des rainures alternantes (56, 60) sont plus profondes, de façon à augmenter la surface ouverte du disque (28) pour faciliter l'évacuation de la vapeur sans réduire de façon significative la rigidité des barres et, en conséquence, la résistance au bris et à la déflexion des barres individuelles (50).
