Abstract

L'invention concerne un dispositif pour usiner la face de bois de sciage, comprenant : une table de travail (10) sur laquelle les bois de sciage sont déplacés, dans une position de travail, dans une première direction de déplacement jusqu'à une butée (24) ; un dispositif de serrage qui bloque les bois de sciage dans la position de sciage, et ; une tête de travail qui peut être déplacée par rapport au dispositif de serrage, dans une deuxième direction de déplacement qui est perpendiculaire à ladite première direction de déplacement. Pour améliorer la sécurité et accroître la productivité, la surface (12) de la table de travail (10) est inclinée d'un angle (a) par rapport à l'horizontale (h) en direction de la butée.
