Abstract

L'invention concerne une dérouleuse pour le bois. Selon l'invention, elle comprend un moyen pour supporter une bille 1 rotative autour de son axe; un couteau 2 orienté en relation tangentielle par rapport à la bille, son bord coupant étant proche du point de tangence; un cylindre d'entraînement placé légèrement en avant du bord coupant du couteau, son pourtour externe étant opposé au pourtour externe de la bille; un certain nombre d'organes de bordure 4 montés sur le pourtour externe du cylindre à des intervalles circonférentiels prédéterminés, et pouvant pénétrer dans une partie du pourtour externe de la bille, qui est sur le point d'être coupée par le couteau; et un moyen 27 pour amener le couteau et le cylindre d'entraînement vers la bille fidèlement par rapport à la rotation de la bille. L'invention s'applique notamment à la préparation de contreplaqué.The invention relates to an unroller for wood. According to the invention, it comprises a means for supporting a ball 1 rotating around its axis; a knife 2 oriented in tangential relation with respect to the ball, its cutting edge being close to the point of tangency; a drive cylinder placed slightly in front of the cutting edge of the knife, its outer periphery being opposite the outer periphery of the ball; a number of border members 4 mounted on the outer periphery of the cylinder at predetermined circumferential intervals, and capable of penetrating a part of the outer periphery of the ball, which is about to be cut by the knife; and means 27 for bringing the knife and the driving cylinder towards the ball faithfully with respect to the rotation of the ball. The invention applies in particular to the preparation of plywood.
