Abstract: Leading and trailing edge stitch tab scrap strippers utilize pivot arms which are secured to die block bodies for pivotable motion intermediate their two ends. One end of each arm is adapted to engage a stitch tab scrap portion to be stripped and to effect the removal of the tab scrap from a box blank from which it has been cut. A biasing force is applied against a second end of the pivot arm. The pivot arm is caused to pivot in response to the rotation of an upper male slotting head and a lower die cutting anvil. This pivotal movement is effective to strip or to eject the severed stitch tab scrap.
