A hot melt adhesive dispensing apparatus comprises a housing including a supply chamber for receiving and holding a solid adhesive, an electrically powered heater, and a spray nozzle assembly. A pneumatically actuated plunger pushes solid adhesive towards the melt chamber wherein the solid adhesive is progressively melted for passage into the spray nozzle assembly which includes a plurality of air jets which impinge upon the stream of melted adhesive exiting a nozzle to create an adhesive spray.
