Abstract: A punching device comprises a housing carrying a main punch body in the form of a plate mounted for rectilinear sliding movement, the punch body comprising a driving rack extending downwardly along each side, and a plurality of integral punch members projecting downwardly in a staggered array, the punch members being waisted. The device comprises an operating handle pivotally mounted on the housing carrying drive pinions engageable with the racks, so that by movement of the handle, the punch body may be raised and lowered. The punch body additionally carries auxiliary punch members, each being mounted on the punch body for longitudinal sliding movement relative thereto.
