ABSTRACT OF THE DISCLOSURE An adjustable die mechanism for extruding a profiled strip of plastic or elastomeric material wherein a plurality of adjacent segments is located upstream and in spaced relation from a final extrusion die assembly having a predetermined profiled opening, with this plurality of segments being mounted for individual and independent adjustment thereof, each segment having one end capable of extending into the extrudate flow channel. Means for actu- ating move the segments relative to the profiled opening in a predetermined manner such that moving the segments into the profiled opening modifies the flow of the extrudate material downstream of the segments as the profiled strip emerges from the die assembly. The die mechanism includes control means for selectively operating the means for moving the segments so as to produce a strip of material having the desired characteristics.
