ABSTRACT:
An apparatus for spraying heated hot melt adhesive in a relatively wide spray pattern comprises a manifold and at least two spray guns mounted side-by-side to the manifold. Each spray gun includes a nozzle having an adhesive discharge passageway which ejects a bead of hot melt adhesive, and a plurality of air jet bores which direct jets of pressurized air to the outer periphery of the adhesive bead to attentuate the bead forming elongated adhesive fibers and to impact a rotational motion to the fibers forming a spiral spray pattern. The air jet bores in the nozzle of one spray gun are angled with respect to the adhesive discharge passageway therein so that the adhesive fibers are rotated in one of a clockwise or counterclockwise direction, whereas the air jet bores in the nozzle of an adjacent spray gun are angled to rotate the adhesive fibers in the other of a clockwise or counterclockwise direction so that adjacent spiral spray patterns are counter-rotating to avoid the formation of eddies or turbulence therebetween.
