Abstract
A method and apparatus for cutting sheet material upon an apertured support surface, the apparatus including a pair of spaced apart parallel cutters. The cutters are spaced apart by a distance greater than a dimension of the apertures, but less than an inter aperture distance so that at least one of the cutters remains in cutting contact with the support surface when the remaining cutter passes over an aperture. The method includes selectively overcutting and undercutting the line segments at an intersection to ensure continuity of cut paths of both cutters.
