ABSTRACT:
The invention is a device for dispensing melted resin on a surface. In detail, the invention includes a housing having an inlet and an outlet passages and a guide passage therebetween. The inlet passage is adapted to receive a solid resin rod and the outlet passage includes a nozzle for dispensing the melted resin to the surface. Also included is a mechanism to sequentially move the rod from the inlet toward the outlet passage. Additionally, a heating coil is positioned about the outlet passage. An air transfer tube is provided having an inlet coupled to and a source of pressurized air and an outlet in proximity to the nozzle. The tube includes a first coil section mounted about the heating coil so that the pressurized air is heated prior to reaching the nozzle such that the surface is heated. The tube also includes a second coil section about the internal passage in series with the first coil section, such that the second coil section is cooled preventing the solid resin from melting until it enters the outlet passage.
