Abstract
A device for cutting a piece of a flat workpiece at a selected location identifiable by two or more binary coded numbers which device includes a cutter, a cutting platen having an upper workpiece supporting surface and a lower portion, a plurality of upstanding, shiftable members, a guiding arrangement on the platen adjacent the lower portion for loosely receiving the members, an arrangement for moving the members in accordance with the coded numbers and a structure for forcing the cutter against the cutting surface. In accordance with another aspect, the shiftable members are movable by binary fluid motors each including a series of axially aligned fluid actuating units having strokes corresponding to binary numbers and an arrangement for actuating certain of these units in the fluid motor to move the shiftable members in accordance with the extended condition of the binary motors.
