Abstract
A process is disclosed for making long wood strands. Long wood strands are required in structural lumber products and in order to obtain maximum strength should be split along the grain. A method of splitting a log into longitudinal-grain wood strands is disclosed comprising the steps of radially splitting the log substantially along the grain of the log into a plurality of sector shaped segments, said radial splitting including pushing the log axially through at least one sector splitter ring, and further splitting the sector shaped segments substantially along the grain of the segments, said further splitting including feeding each of the sector shaped segments through two rows of intermeshing counter rotating discs, pulling each of the segments between the rows of discs and simultaneously splitting each of the segments into a plurality of longitudinal-grain wood strands.
