Abstract

A device for selectively securing a stripper assembly on a punch guide assembly. A resiliently biased plunger is disposed adjacent the guide assembly, and selectively maintains the stripper assembly in a predetermined rotational position relative to the guide assembly. The stripper assembly includes at least one retaining projection, and the guide assembly includes at least one flange for selective engagement with the retaining projection to secure the stripper assembly and the guide assembly against relative axial movement. A method is disclosed including the steps of placing the stripper assembly on the guide assembly, and affecting relative movement between the stripper assembly and the guide assembly to cause the retaining projection to engage the flange, and the plunger to be received in a locator slot on the stripper assembly.
