Abstract (en)

[origin: WO0000331A1] 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.
