The invention relates to a chipping, a method and device for producing said chipping, and to the use thereof. The chipping (10') is made of wood. It has a first concave surface (12) and a second concave surface (12). The wedge-shaped chipping (10') is defined substantially between both surfaces. The surfaces (12, 14) converge in an imaginary apex (16) outside the chipping. The chipping (10') is cut using a rotating chip cutting tool. Before said cutting occurs, the wood is removed in the area where the surfaces (12,14) converge in the imaginary apex (16), preferably using a circular saw that is mounted upstream from the head of the chipper.
L'invention concerne un copeau, un procédé et un dispositif pour produire ce copeau, ainsi que leurs utilisations. Le copeau (10') est constitué de bois. Il présente une première surface concave (12) et une deuxième surface convexe (14) qui délimitent entre elles le copeau (10') sensiblement cunéiforme. Les surfaces (12, 14) convergent en une pointe imaginaire (16) à l'extérieur du copeau (10'). Ce dernier est découpé à l'aide d'un outil d'enlèvement de copeaux rotatif. Avant ce découpage, le bois est enlevé dans la zone où les surfaces (12, 14) convergent dans la pointe imaginaire (16), de préférence à l'aide d'une scie circulaire montée en amont de la tête de l'outil d'enlèvement de copeaux.
