ABSTRACT:
A device and method for spraying hot melt glue in circular patterns of varying diameters is disclosed. The device uses a single jet of pressurized air caused to spin and forced into a series of passages to produce a conical curtain of air. The conical air curtain impinges upon a stream of hot adhesive to spin and guide it on a surface in a circular pattern. The relative positions of the air and glue emission orifices may be adjusted quickly and easily to provide fine control of the spray pattern diameter while achieving patterns having diameters ranging from approximately one-half to fifteen inches. Spiral glue patterns may be created merely by moving the nozzle of the device relative to a surface in a substantially straight line.
