The provision of a hardened elevated surface within the a inside die cutting area of a cutting rule to limit and control the extent to which die cut scrap processed corrugated fiberboard sheet material can position itself within the area within the cutting rule before ejection limit the tendency for instability within the cutting rule after the die cut is achieved and to better control the ejection of the scrap processed corrugated fiberboard sheet material to better eliminate unwanted scrap downstream of the die cutting process. Eliminated scrap reduces malfunctions in further processing and helps to eliminate health and contamination hazards in the finished corrugated fiberboard sheet product.
