An adhesive dispensing die module for mounting on a manifold incudes (a) a die body having formed therein polymer and air flow passages, and a valve for selectively closing the polymer flow passage and (b) a die tip or die nozzle detachably mounted on the die body. The die tip or die nozzle is secured to the die body by a pair of clamping members depending from the die body and adapted to engage die tip or die nozzle therebetween. The clamping members can selectively be moved toward one another to clampingly secure the die tip or die nozzle therebetween or moved away from one another to release the die tip or die nozzle, permitting it to be replaced without the need to remove the die module from the manifold.

[What is claimed is:] [1.](a) a die body having(i) an air flow passage formed therein(ii) a polymer melt flow passage formed therein,(iii) valve means for opening and closing said polymer melt flow passage; and(iv) a nozzle mounting surface;(b) a nozzle positioned on said mounting surface of said die body and having at least one orifice formed therein and air passages formed therein, said orifice and said air passages being in fluid communication with said polymer melt flow passage and said air passage of said die body, respectively, and(c) a clamping structure affixed to said die body for clamping said nozzle securely to said mounting surface of said die body by the application of clamping force on opposite sides of said nozzle with a force component substantially parallel to said nozzle mounting surface, said clamping structure including a hinged member pivotally affixed to said die body and pivotally movable between a clamped position and an unclamped position thereby permitting said nozzle to be removed from said mounting surface.
