ABSTRACT:
A blade sharpener for band saws used in the lumber and other wood processing industries, is installed on the band saw structure for sharpening the band saw blade periodically as required without need to remove the blade from the saw. The sharpener apparatus is retractable within the band saw frame when not in use, permitting the saw to be used normally. When the blade requires sharpening, the apparatus is extended and clamped about the blade. The blade is advanced to the proper position, and the sharpener is actuated to sharpen each of the teeth of the band saw blade in place on the saw. The mechanism includes an automatic shutoff to preclude further sharpening operation once the blade has been advanced through a full cycle and all teeth have been sharpened. The sharpener also includes adjustments for tooth pitch, hook angle, and tooth or gullet depth, enabling the device to be useable for sharpening virtually any band saw blade configuration.
