Abstract:
A film extrusion apparatus or nozzle which includes a pair of oppositely disposed, spaced elongated blades which together define an extrusion orifice of generally uniform width. At least one of such blades is slotted to impart limited flexibility to an exposed terminal corner portion thereof which assists in defining an end of the extrusion orifice. Means are provided for selectively deflecting the exposed, flexible corner portion of the one blade to thereby vary the width of the extrusion orifice along the end thereof.
