ABSTRACT:
A hot-melt adhesive dispenser having spray nozzles connected to a nozzle manifold receiving hot-melt adhesive material from a heated dispenser head. The spray nozzles have a pair of flow paths, one within the other, terminating near the nozzle outlet. A stream of low pressure air flows from a valve, through a plurality of tubes to at least one hollow gas injection conduit in the nozzle forming an inner flow path. Hot-melt material flows through a dispensing bar to a nozzle body cavity and opening defining the outer flow path. Hot-melt material is projected from the nozzle, broken up into droplets by the expanding gas, producing a spray within about three inches of the nozzle outlet. A pair of spaced apart dispensers with spray nozzles are used to spray seal the upper and lower flaps of cartons.
