PROBLEM TO BE SOLVED: To form a glued laminated timber having an excellent strength and quality at a low cost by effectively utilizing a sapwood from a log which has been heretofore limited in an application and wastefully consumed.;SOLUTION: A method for manufacturing the glued laminated timber comprises the steps of preparing the sapwoods 3, 3 generated in the case of cutting out a core material 2 from the log 1, cutting off a bark side from the sapwood parallel to the face of the pith side to form plate-like materials 5, 5 to become substantially plate-like material shapes. The method further comprises the steps of laminating the plate-like materials so that the cut-off faces are superposed in a state in which the bark sides are directed in the same direction or in a state in which the mark sides are directed in opposite directions, laminating the materials, then cutting off the edge parts to form the glued laminated timbers 8, 9.;COPYRIGHT: (C)2002,JPO
