The invention relates to a vertical dosing hopper for producing boards consisting of derived timber products. Said hopper is arranged above a dispersion head for glued wood particles. The supply of particles is provided essentially in the vertical direction and the wood particles are transported essentially downwards to a discharge device (18, 48). The invention is characterised in that the hopper is provided for flat, elongated wood particles or wood chips (strands) for producing boards comprising oriented wood chips (OSB, LSL). The supply chamber comprises at least one vertical conveyer shaft (13) by which means the flat, elongated wood chips are continuously delivered to a discharge device (18, 48). The conveyer shaft essentially consists of two conveyer strips (14, 15, 46, 47) which are arranged opposite each other in a parallel and vertical manner, and which extend over the entire width of the hopper.
L'invention concerne un caisson de dosage vertical utilisé pour produire des panneaux en matériau dérivé du bois, qui est monté au-dessus d'une tête de saupoudrage pour particules de bois encollées. La réserve de particules est prévue sensiblement dans le sens vertical. A cet effet, les particules de bois sont acheminées sensiblement de haut en bas jusqu'à un dispositif de décharge (18, 48). L'invention se caractérise en ce que le caisson pour particules ou copeaux de bois plats allongés (copeaux longs) est prévu pour produire des panneaux à copeaux de bois orientés (OSB, LSL). A cet effet, l'espace de réserve comprend au moins une trémie d'alimentation (13) verticale dans laquelle les copeaux de bois plats allongés sont acheminés en continu jusqu'à un dispositif de décharge (18, 48). La trémie d'alimentation comprend à cet effet sensiblement au moins deux bandes transporteuses (14, 15, 46, 47) opposées parallèlement et verticalement qui s'étendent sur toute la largeur du caisson.
