Abstract

A method and apparatus for cutting sheet material allows multiple layups of sheet material to be cut in side-by-side or stacked relationship on the cutting table of a computer controlled cutting machine. A different marker or array of pattern pieces can be cut from each of the stacked layups. Also, for certain layups, whether stacked or not, markers are located with reference to the centerline of the layup to insure that the pattern pieces of the marker are cut symmetrically or in alignment with ornamentation or designs in the material.
