A hot melt adhesive dispensing nozzle or die as- sembly spans two adjacent adhesive material valued inlets. One of the valued inlets is blocked off by means of the noz- zle or die assembly, while the other adhesive material input or valued inlet is in effect split into two equal laterally separated output arrays of dispensing nozzles so as to pro- vide for a void in the dispensing or deposition pattern at a predeterminedly desired location. The nozzle or die assembly comprises unique structure for ensuring that the hot melt adhesive material is able to be conducted to the remote one of the laterally separated array of dispensing nozzles. In addition, the two laterally separated arrays of output dis- pensing nozzles together comprise the same number of conven- tional non-split output dispensing nozzles operatively asso- ciated with each adhesive material input or valued inlet such that the volume flow rate through each one of the indi- vidual dispensing nozzles remains the same. In this manner, the aforenoted pattern void is achieved while preserving the desired ratio of heated air to adhesive material whereby the hot melt adhesive material being dispensed retains its prop- er fluidic properties, and undue waste of the adhesive ma- terial is not incurred.
