ABSTRACT:
A foil perforating apparatus of the type wherein perforation locations on a large master pattern are transferred via a reduced motion system, such as a pantograph, to corresponding locations on a transparency foil to be punched. A foil punching device is carried on the reduced motion system. Accuracy of punching is achieved by a clamping means on the reduced motion system which is electrically interlocked with the foil punch to achieve clamping prior to punching.
