Abstract
A multiple punch and die assembly body member has dies or strippers that are held within multiple pockets in a multipunch body member by means of a centrally positioned retaining member formed from a rigid or flexible material located in a central recess at the middle of a ring of the surrounding dies or strippers. The retaining member is preferably held in place by a push plate that can be secured to the multipunch body member by a tightening element, e.g., a screw fastener for pressing the peripheral surface of the retainer member into engagement with the dies or strippers to hold them in their respective pockets in the multipunch body member.
