Fastening sheets together by punching.- In apparatus for fastening sheets together by punching, the central rod B carrying the cutting and fastening devices and the holding-down plate C, is extended below the latter and engaged at its lower end by a leaf-spring D, a comparatively weak spiral spring A being located on the rod above the holding-down plate. A front plate with stamped-out lugs is sprung inside or outside the frame G to enclose the mechanism.
