Abstract
An apparatus for spraying droplets of molten thermoplastic adhesive comprises a spray device having a nozzle formed with a discharge outlet which ejects a continuous stream of molten thermoplastic adhesive. A stitcher device connected to a source of pressurized air is operative to supply intermittent, pulsed jets of atomizing air to air jet bores associated with the nozzle which discharge the pulsed air jets into contact with the exterior of the continuous stream of molten thermoplastic material forming well defined globules or droplets for deposition onto a substrate.
