ABSTRACT:
A slot nozzle die for use with a coating dispenser includes a first die body having a tapered projection and a deflectable tab member horizontally spaced from the tapered projection to define a die seat therebetween. A second die body having a tapered projection is slidably received in the die seat formed in the first die body. The tapered projections of the first and second die bodies define an extrusion slot therebetween which receives coating material from the coating dispenser. A pair of air blocks are respectively mounted to lower ends of each die body to define a pair of air channels disposed at an angle relative to the extrusion slot. One of the air blocks is slidably received intermediate the deflectable tab member and the tapered projection of the second die body and cooperates with the deflectable tab member for translating the tapered projection of the second die body toward the tapered projection of the first die body to seal the first and second die bodies.
