Abstract

L'invention concerne un appareil de dispersion servant à disperser une matière fibreuse (1), qui comprend un boîtier (2) dans lequel sont disposés un premier outil de traitement (3) et un second outil de traitement (4), lesdits outils de traitement (3, 4) ayant respectivement une forme à symétrie de rotation, étant disposés coaxialement l'un par rapport à l'autre et présentant respectivement des dents (6) agencées en plusieurs rangées (5) annulaires concentriques à leur centre. Lesdites dents présentent des entredents entre elles, qui sont parcourus dans le sens radial par la matière fibreuse (1). Entre les rangées de dents (5), des espaces intermédiaires annulaires sont ménagés de sorte qu'au moins une rangée de dents (5) d'un outil de traitement (3, 4) parvienne dans un espace intermédiaire annulaire de l'autre outil de traitement complémentaire (4, 3). A cet effet, la dispersion doit être améliorée, en ce qu'au moins quelques dents (6) d'au moins un outil de traitement (3, 4) comportent au moins une rainure (9) radiale qui ne s'étend que sur une partie de l'espace séparant la base de la dent (14) de la tête de la dent (10):
