Abstract
A perforation system and method of perforating a flexible work piece. The perforation system includes a punch tool having at least one punch head defining a vertical axis. The punch head has a first shape. A die is positioned along the vertical axis and includes an ejection port having a second shape. The first shape overlaps the second shape to provide for punch-to-die contact that results in a clean cut along a perimeter of the second shape.
