Abstract
The present invention is generally directed to a die cut assembly for a roller die cutting machine having a base member, a cutting rule, and a compressible top layer. Base member is generally a rectangular shape, having a length, width and thickness. A cutting rule including a cutting edge is formed into a pattern containing a plurality of geometric shapes. The pattern containing geometric shapes is formed to include each geometric shape sharing a common point when the shape allows it. Cutting rule is generally coupled to the base member at a skew wherein no side of the pattern is transverse to the length of the base member. The compressible top layer is coupled to the base member. Generally, cutting rule nests in compressible top layer and compressible top layer extends beyond the cutting edge of the cutting rule.
