ABSTRACT:
An apparatus and method for finishing the lengthwise extending edge of a foil including a finishing material mounting assembly for supporting a finishing material and a reciprocating jig assembly for holding the foil so as to position its one edge toward the finishing material and reciprocating the blade in its lengthwise direction simultaneously over one travel distance at one rate and a shorter travel distance at a more rapid rate. The finishing material mounting assembly includes a yieldable pressure means for urging the finishing material into tangential engagement with the edge of the blade. The jig assembly includes a rotatable jig head to enable the foil to rotate about its lengthwise axis, and the pressure means includes a relief means for imparting an oscillating rotating motion to the foil as it is reciprocated and to conform the finishing material to the contour of the foil edge, resulting in a rounded finished edge on the foil.
