ABSTRACT:
A method of slicing wood by moving a wooden workpiece on a linear path, and forcing one end against a blade directed longitudinally along the grain, applying pressure on both sides of the workpiece, on opposite sides of the blade by means of pressure pads, and, allowing the pressure pads to move relative to the blade, while maintaining equal spacing between themselves, so as to equalize the compressive force on both sides of the workpiece in the region of the blade, and an apparatus for carrying out the method.
Also disclosed is a wood slicing blade with angled cutting edges, which is short and stiff, and a blade holder assembly arranged to tension the blade laterally.
