Abstract
An extruder nozzle for producing a relatively wide flat ribbon of extruded fluid is provided. The extruder nozzle includes a groove in communication with the orifice of the nozzle, the groove being generally arcuate in shape and so dimensioned that the ends of the arc are closer to the extrusion point than is the center so as to cause the orifice to fill completely and thereby permit the extrusion of a relatively wide flat ribbon. A shim means is provided to establish the size of the orifice and to cut off the arcuate groove at each of its ends to establish a reservoir of fluid at each end of the groove and thereby eliminate the formation of a needle or the like at the lateral edges of the extruded ribbon. Shim means of various thicknesses may be utilized to control the thickness (or depth) of the extruded ribbon.
