Abstract
To date, it has been difficult to extrude precision films onto large substrates efficiently, thus, limiting the size of the substrate. One reason for the difficulty is natural sag or deflection in an extrusion head applying the film to the substrate. To counteract this deflection or sag, a crossbar has been designed that provides a substantially rigid platform to mount an extrusion head, which counteracts the deflection or sag, thus allowing for efficient extrusion of precision films over exceedingly large substrates.
