Title: MULTILAYER WOOD PANEL AND METHOD FOR CUTTING AND ASSEMBLING SQUARED GREEN WOOD FOR PRODUCING SUCH A PANEL
Abstract:
The invention concerns a wood panel (P, P') comprising several layers of squared wood cut and assembled while green prior to final drying, said panel being characterised in that it is a cross-laminated panel (P,P') in which the grain of successive layers of squared wood (50, 51, 52; 50', 51', 52'; 60, 61, 62) is oriented alternately at 90°, in that each layer of squared wood (50, 51, 52; 50', 51', 52'; 60, 61, 62) has a main bonding surface (Sc) in a longitudinal-radial reference plane (LR) of the wood, and in that the axis tangential to the growth rings (c), which are visible on the cross-section of each piece of squared wood (10, 11, 12, 13, 14, 15…; 20, 21, 22…; 30, 31, 32 …; 10', 11', 12',…; 20', 21', 22', …; 30', 31', 32' …) constituting each layer, forms an angle of between 45 and 135° inclusive with said main bonding surface (Sc).
