Title (EN) CONVEX WOODCHIP BOARD
(FR) PANNEAU DE PARTICULES DE BOIS CONVEXE
Abstract:
(EN) The invention relates to a method for manufacturing a woodchip board (3) comprising a first (21) and second (23) woodchip layer sandwiching an intermediate layer (12) comprising woodchips of other chip size than the first (21) and second (23) woodchip layer. The method comprises the steps involving application of a first quantity (5) of glued woodchips (7) to a lower tool face (9) of a pressing tool (1, 31); application of a filler quantity (11) of glued woodchips (7') to the first quantity (5); application of a second quantity (13) of glued woodchips (7) to the filler quantity (11); compression of said quantities (5, 11, 13) by means of the lower (9) tool face and an upper tool face (15); realization of differentiated times when the glue of the glued woodchips (7) hardens in the first (5) and second quantity (13) respectively, by virtue of the production of these quantities with different thickness and/or by heating of the respective quantities (5, 13) to different temperatures; and removal of the hardened woodchip board (3) from the pressing tool (1, 31).
(FR) L'invention se rapporte à un procédé de fabrication d'un panneau de particules de bois (3) comprenant des première (21) et seconde (23) couches de particules de bois placées de part et d'autre d'une couche intermédiaire (12) comprenant des particules de bois d'une taille différente de celle des première (21) et seconde (23) couches de particules de bois. Le procédé comprend les étapes consistant à appliquer une première quantité (5) de particules de bois collées (7) sur la face inférieure (9) d'un outil de pressage (1, 31), à appliquer une quantité donnée (11) de particules de bois collées (7) de garnissage sur la première quantité (5), à appliquer une seconde quantité (13) de particules de bois collées (7) sur la quantité de particules de couche intérieure (11), à comprimer lesdites quantités (5, 11, 13) à l'aide de la face inférieure (9) et d'une face supérieure (15) d'outil, à obtenir des temps différenciés de durcissement de la colle des particules de bois collées (7) entre les première (5) et seconde quantités (13) respectivement, par application desdites quantités à des épaisseurs différentes et/ou par chauffage des quantités respectives (5, 13) à différentes températures, et à retirer le panneau de particules de bois durci (3) de l'outil de pressage (1, 31).
