<p>A saw mill apparatus (10) supports and advances a log (12) towards the saw mill's saw assembly (14, 16), and cuts log (12) longitudinally by a pair of parallel band saws (14, 16). Blade guides (26, 28) are mounted to each band saw blades (22, 24) and are movable along the blades (22, 24) toward and away from the log (12) being cut by means of hydraulic positioners (38, 40). The diameter of the log (12) is sensed by a scanning device (20) at plural longitudinal positions of log (12). A control system (not shown) controls the height of the blade guides (26, 28) in response to each of the sensed diameters so that the guides (26, 28) properly track the diameter of log (12) during cutting.</p> |
