ABSTRACT:
A T die for extruding a low viscosity resin film coating especially in the manufacture of adhesive tapes. Uniform extrusion from the die is accomplished by the flow of melted resin from a supply manifold through a large number of narrow passageways into a smaller pressure equalizing manifold and out of a die slit extending the entire width of the die, the width of the die slit being adjustable in order to regulate the unevenness of the yield product.
