A viscous material dispense system including a dispense valve having an outlet, a mix tube secured at an upper end thereof to the outlet of the dispense valve, a mixer shroud positioned telescopically over the mix tube and including a conical lower end, and an air shroud fitted telescopically over the lower end of the mixer shroud and defining a conical surface positioned in confronting relation to the conical tip portion of the mixer shroud. The air shroud and the lower end of the mixer shroud coact to define a plurality of circumferentially spaced axially extending flutes extending downwardly between the outer surface of the mixer shroud and the inner surface of the air shroud and a plurality of circumferentially spaced radially extending flutes defined between the conical tip portion of the mixer shroud and the conical surface of the air shroud. Each radial flute communicates with a respective axial flute so that air enters proximate the upper end of the air shroud, moves downwardly between the air shroud and the mixer shroud as a series of axially spaced air streams, and thereafter moves radially inwardly between the lower end of the mixer shroud and the air shroud as a plurality of radially inwardly moving air streams which impinge upon a material bead exiting from the lower end of the mix tube to impart a swirling movement to the bead.

1. A viscous material dispensing system comprising:a dispensing valve having an outlet; a nozzle assembly including a tubular nozzle member having one end secured to the dispense valve outlet for receiving viscous material from the dispense valve for passage through the nozzle member, the tubular nozzle member having another free end defining a nozzle tip portion having a conical nozzle surface, and an axially extending main body tubular portion interconnecting said one end and the nozzle tip portion; and dispensing means proximate the nozzle tip portion of the nozzle member operative for discharging viscous material from the nozzle assembly, the dispensing means including a tip insert insertable into the nozzle tip portion, said tip insert having a smaller end aperture than the nozzle tip portion of the nozzle assembly, wherein the tubular nozzle member has a mixer member disposed therein.
