Abstract

Un couteau de sole (1) pour rabot à charbon, comprenant une barre en métal fritté (3) constituant la transition entre le tranchant de front de taille (4) et le tranchant de sole (5), à laquelle se raccordent sur les deux cotés des plaques en métal fritté (6,7) formant le tranchant de front de taille ou le tranchant de sole. Pour éviter des casses des plaques en métal fritté au niveau des transition avec la barre en métal fritté (3), l'invention propose de munir d'évidements en forme d'auges (8,9) sur les deux cotés en vue de la réception des régions d'extrémité des plaques en métal fritté voisines (10,11). Les évidements en forme d'auges de la barre en métal fritté sont dans ce cas avantageusement conformés de manière que les lignes de sommet (12, 13) entre les plaques en métal fritté et la barre en métal fritté rencontrent sensiblement à angle droit le tranchant de front de taille ou le tranchant de sole.
