Abstract
Improved steel rule for use in a cutting die for cutting fixed patterns in a single or plurality of stacked material layers according to the shape of the steel rule. The improvement in the rule assists in the removal of small pieces of scrap material through the bottom of the die. The rule is undercut so that the gap between adjacent cavities is tapered. The tapered gap between adjacent cavities creates a vertical passageway that becomes wider toward the bottom of the passageway. This greatly facilitates removal of scrap material through the bottom of the die. By allowing scrap material to escape through the die, the operators are not required to stop periodically to clean the die, and the likelihood of scrap material becoming trapped in the die is minimized. Thus, the speed of the cutting operation is increased and life of the die may be prolonged.
