PLYWOOD WHEREIN GRAIN AND FIBER ON TWO SIDES OF SURFACE AND BACK OF PLYWOOD ARE DIRECTED PERPENDICULARLY

摘要

PROBLEM TO BE SOLVED: To provide a ply wood useful for cutting cost and reducing an environmental load by reducing an amount of fragment waste with surfaces of two types of the directions of the grain and the fiber on two faces of the front and the back sides of the ply wood by making the grain and the fiber direct perpendicular. SOLUTION: To produce the ply wood having the directions of the grain and fiber on the front side and the back side being perpendicular by making the number of veneers for stacking in the ply wood even and stacking them with grain and fiber directing perpendicular (crossing).
