Abstract

Procédé et dispositif pour réaliser des faisceaux ligneux à partir de rondins de bois. On place un rondin de bois vert ou mouillé sur un plateau circulaire horizontal rotatif, l'axe transversal dudit rondin étant disposé sensiblement selon un rayon du plateau circulaire, ledit plateau comportant une pluralite de touffes de fils métalliques faisant saillie de sa face supérieure recevant le rondin, et on fait tourner ledit plateau avec une vitesse prédéterminée afin de réaliser la défibrillation du rondin au contact des touffes de fils métalliques dudit plateau. Application à l'obtention de faisceaux ligneux constitués de fibres de bois dont la longueur est généralement comprise entre environ 5 et environ 200 mm, dont l'épaisseur est inférieure à 1/10 de mm et dont la largeur est inférieure à 5/10 de mm.
