Abstract (en)

Method for production of multilayer blockboard from solid coniferous wood lamella of increased hardness and abrasion resistance is made by having those lamellas of the same thickness with milling of the surface which forms the glue fugue sorted and chosen, which width of growth rings does not exceed 2,5 mm and which grain arrangement in proportion to the working surface is at an angle of 90 degrees with a deviation in both directions of no more than 25 degrees for lamellas of a thickness of from 10 - 14 mm. One of the milled sides of the lamella is covered with a class D4/C4 resistant adhesive and is connected into the panel. The glued in the press panel is calibrated and afterwards the calibrated panel is glued crosswise into a standard blockboard with the use of glue as stated before. A panel of a thickness above 14 mm is in turn cut again into lamellas transverse to the configuration of growth rings and lamellas are again glued into the panel and afterwards the monolayer panel prepared in such a way is calibrated and glued into a multilayer blockboard with lamellas put crosswise, whereas the finished panel is calibrated and finally the grinded panel is covered with hot melt curing agents.
