ABSTRACT OF THE DISCLOSURE A foam extrusion die assembly includes a die body and a pair of spaced cantilevered lip members having opposed lips defining an elongated, arcuate die orifice through which extrudate moves both laterally and axially outwardly relative to the lip members. Each lip member further has an axially extending flexible leg and a foot at the end of the leg opposite the lip. Each foot is adjustably and sealingly clamped to the die body by a retainer bar whereas each leg is free to flex to pivot the lips with respect to each other. Adjustment screws journaled in the die body vary the spacing between the feet of the lip members and pivot the lips about the flexible legs to produce a desired die orifice size and shape.
