ABSTRACT:
A veneer lathe is provided with back-up rolls modified to include serrating knives to effect cutting a log longitudinally at predetermined circumferentially spaced apart intervals to define the width of wood strands, and also to include scribing cutters to effect cutting a log circumferentially at longitudinally spaced apart intervals to define the length of wood strands, whereby when the log is rotated past the peeler knife of the lathe, the thickness of wood peeled from the log breaks apart into a multiplicity of vertical grain strands of predetermined length, width and thickness.
