<P>PROBLEM TO BE SOLVED: To manufacture diagonal plywood at a low equipment cost and with high productivity. <P>SOLUTION: A plywood board 11 having sides 11a, 11b is sequentially cut along cutting lines 11c inclined with respect to the side 11a and spaced at an interval L to manufacture band-shaped plywood boards 13a, 13b, band-shaped plywood boards 13c, 13d, .... Then while two cutting lines 11c of the band-shaped plywood boards different from each other are positioned on the same straight line, the band-shaped plywood boards are joined at the side 11a or 11b to obtain a joined plywood board 15 or 17, and then the joined plywood board 15 or 17 is cut orthogonally to the cutting line 11c at a suitable interval. <P>COPYRIGHT: (C)2013,JPO&INPIT |
