Plastic paper punch with axially reciprocable punch heads

Abstract

A paper punch comprising a one-piece die body, a one-piece press body, and a plurality of one-piece punch heads; the die body and press body being pivoted along a rocking axis for a rocking motion between an inactive position and an active position, the punch heads operating therebetween; the die body providing a base with die holes, guides with guide holes, and a paper reception region therebetween; the punch heads being constrained by the guide holes for reciprocation along the axes of the die holes and the guide holes; the press body controlling axial retraction of the punch heads from the paper reception region, and projection of the punch heads through the paper reception region and into the die holes, the inactive position being where the punch heads are substantially fully retracted from the paper reception region and the active position being where the punch heads are substantially fully projected into the paper reception region; the punch heads having slides at one extremity; guide channels in the press body for the slides by which reciprocation of the punch heads is controlled; the die body and press body having journals for establishing the rocking axis; and the rocking axis being located between the punch heads and the rearward edge of the press body and the rearward edge of the die body.
