ABSTRACT:
A punch for a cutting die is provided for forming holes in corrugated board or the like. The hole punch includes a tubular metal member of circular transverse cross section having one end substantially flush with the back surface of a die plate in which it is mounted and the other end extending beyond the front surface of the die plate and terminating in a circular cutting edge. A body of resilient material, preferably molded rubber, is located within the cylindrical member and has one end terminating near the back end of the tubular member and another end terminating near the cutting edge of the tubular member. The purpose of the body is to eject and strip the scrap of corrugated board from the punch and from the rest of the blank being formed by the cutting die. The resilient body has a central, cylindrical recess at one end which enables the resilient material to be deformed inwardly when engaging a corrugated board being cut by the circular cutting edge. The other end of the resilient body is closed off which enables the body to be more easily inserted in the tubular metal member. This end is also chamfered which increases the life of the resilient body.
