Abstract (en)
[origin: WO2015185789A1] In a method for manufacturing plywood, veneers are stacked to produce plywood that comprises a surface veneer layer (A) on both sides of plywood (1), the surface veneer layers (A) having their grain running in a first direction; 2-4 oriented veneer layers (B) next to each surface veneer layer (A), the oriented veneer layers (B) having their grain running in a second direction which is perpendicular to said first direction; and a plurality of interior veneer layers (C) having their grain alternately in the first direction and the second direction so that the interior veneer layers (C) form a cross-bonded structure. The veneers are arranged so that the average density of the oriented veneer layers (B) is higher than the average density of the plurality of the interior veneer layers (C).
