System and method for transporting and clamping flexible film structures

Image Number 4 for United States Patent #5957360.

One or more porous air film rolls are used, in a system to support a flexible web during movement of the web, and selectively provide either compliant or rigid clamping of the web while performing processing operations on the web at a work station. The present invention is particularly suitable for punching holes on-the-fly, in both "X" and "Y" directions, in a flexible polyamide film. Up to a four-fold increase in punch tool productivity is provided by the present invention.
