ABSTRACT:
A punch apparatus for punching holes in thin sheet material including a frame, a punch element mounted on the frame for rectilinear movement, which further includes a planar element of conductive material mounted on the punch element, a coil on the frame mounted adjacent to the planar element, a carriage for supporting and positioning the sheet in the path of the punch element, leads connected to a source of electric current to energize the coil, a mechanical arrangement to rebound the punch element, and a programmable apparatus to selectively move the carriage and energize the coil to thereby produce a punched hole pattern in the sheet.
