Abstract
A nozzle for a hot melt adhesive spray head which mounts directly to a nozzle mounting surface. To permit a series of spray nozzles to be mounted closely together, the nozzle has a threaded stud integral with and extending from the rear side of the nozzle. The adhesive passage in the nozzle mounting surface has a threaded bore for receiving the threaded stud of the nozzle. The nozzle includes a first O-ring seal to prevent the pressurized pattern air from leaking between the nozzle and the nozzle mounting surface. A second O-ring seal isolates the hot melt adhesive from the pressurized patten air at the interface between the nozzle and the nozzle mounting surface.
