ABSTRACT:
A device designed to stamp generally rectangular blister packages from an intermittently advancing laminated strip comprises a die with rounded corners whose radii of curvature are substantially larger at a transverse leading edge than at a transverse trailing edge as seen in the direction of strip motion. The width of the die slightly exceeds the advance of the strip between cutting operations whereby packages stamped from the strip exhibit obtuse angles but no pointed projections at their forward edges.
