ABSTRACT:
A nozzle adapter for spraying liquid hot melt adhesive which includes a mounting plate, an adapter body fastened to the mounting plate and a nozzle unit received for rotation between the mounting plate and the adapter body. The nozzle unit may be rotated between a first position which is operative to dispense liquid and a second inoperative position which preferably redirects the liquid out of the adapter so that the liquid may be recirculated. The first position is also operative to discharge air against the liquid being dispensed to create, for example, a swirling bead pattern. In the second position, the air discharge of the nozzle unit is blocked.
