Abstract
Apparatus for sharpening cutters distributed along a saw chain, the apparatus including a support track along which a reach of saw chain may be moved and multiple sharpeners spaced along the path for sharpening cutters carried thereto. Multiple cutter engaging elements are operable to engage selected, spaced cutters on the reach of chain and shift them into approximate sharpening positions adjacent the sharpeners, at which point cutter holding clamps operate to precisely position the cutters relative to the sharpeners. The cutter engaging elements, holding clamps, and sharpeners are so spaced in the apparatus that slack is maintained in the portions of the chain between the selected cutters throughout movement in the apparatus and sharpening.
