Appellants’ claimed invention is directed to an apparatus and method
for trimming scrap from a blank. The apparatus comprises, inter alia, steady
and moving blades for trimming the blank wherein a radius is provided on
the leading edge of the moving blade to reduce defects in the blank that are
associated with the trimming process. The apparatus also comprises a
support element for the trimmed scrap that moves substantially
perpendicular to the upper surface of the blank.
