  • Method and system for punching holes in a sheet material
    Patent number: 5214990
    Abstract: A method and system for forming an artwork on a sheet material and punching holes therethrough while the sheet material is disposed on a working surface so that the holes are punched in precise registration with the artwork. The method comprises the steps of providing for each hole to be punched a corresponding socket in the working surface, and securing the sheet material on the working surface so as completely to overlap all of the sockets whereupon the artwork is formed on the sheet material in precise registration with a predetermined origin of the working surface. Associated with each of the sockets is a punch and block combination disposed on opposite surfaces of the sheet material, the block being formed of a softer material than the punch and having an operating surface larger than a cutting surface of the punch.
