ABSTRACT:
A process for preparation of long wood strands is disclosed. Long wood strands are required for the production of structural lumber products. These strands must be split, and a method of splitting logs into longitudinal-grain wood strands comprises the steps of radially splitting a log substantially along the grain of the log into a plurality of sector shaped segments, parallel splitting each of the sector shaped segments along the grain of the segments into a plurality of substantially parallel slabs, and further splitting each of the parallel slabs substantially along the grain of the slabs into a plurality of longitudinal-grain wood strands.
