ABSTRACT:
Blade sharpener apparatus and method for ice resurfacing and paper cutting machines includes a table for laying a longitudinal blade in a stationary position thereon. A moveable carrier assembly attached to the table has a drill press power head that is lowered from a raised position so that a rotatable sharpening wheel is positioned at a selected angle against the edge of the blade. A stabilizing guide can slide under the table while the sharpening wheel and an additional guide wheel rolls across the longitudinal blade. Liquid can continuously cool the blade sharpening, and can be recycled for reuse. Another embodiment eliminates the rotating guide wheel, and attaches the carrier to the table so that only the rotating wheel contacts the blade. A hinge can support the carrier, and be adjustable by a rotatable bolt type member to different sharpening angles. A threaded guide rod can be rotated in place along the table so that a mateable threaded portion on the carrier can move along the guide rod. Power to operate the sharpening wheel and the moveable carrier can be supplied by electrical motors, and the like.
