Abstract: A method is provided for forming cutting edges. The method includes a step of providing a grinding stage comprising a pair of abrading wheels that extend from a strip receiving end to a strip exiting end. The method further includes a step of directing a strip of metal at the strip receiving end of the grinding stage along a path P. The method also includes a step of removing material, from the strip of the metal, with an abrasive surface along the pair of abrading wheels which varies from a fine abrasion to a coarse abrasion in a direction from the strip receiving end to the strip exiting end.

Abstract: An apparatus is provided for forming cutting edges including a grinding stage. The grinding stage includes abrading wheels with a strip receiving end configured to receive a strip with a first profile along a path P and a strip exiting end. Axes of the abrading wheels are oriented at a tilt angle relative to the path P. Lands are provided on each abrading wheel with an abrasive surface that varies from fine to coarse in a direction from the strip receiving end to the strip exiting end. The lands are arranged in a spiral helix such that the helix is a right-handed thread on one wheel and a left-handed thread on the other wheel. An improvement is also provided for a system for removing material from a strip of metal incident on the system along a path P.
