ABSTRACT:
A punch for making a multiplicity of holes in a line even through a multiplicity of sheets of paper put one upon another includes a multiplicity of vertically disposed and vertically movable cutting tools supported in a row by a horizontally disposed rail. Each tool is provided with a horizontally disposed actuator pin attached to it at right angles to it. A slider is slidable along the rail for causing the pins to move the tools vertically one after another. The slider has a pair of curved guide grooves in which the opposite ends of each pin are engageable, or a roller having a pair of annular surfaces which are engageable with the opposite ends of each pin, so that the pins and thereby the tools may be vertically movable.
