ABSTRACT:
A device for preventing trailing of glue extruded by an exclusion nozzle following termination of the dispensing of the glue. A pair of spaced apart orifices are positioned to direct a thin jet of air for a brief period of time on either side of the stream of glue being dispensed at the moment of glue cut-off to momentarily entrain the stream and draw it generally in the direction of the path of travel of the workpiece. The air jets are oriented so as not to touch or impinge on the glue stream, thereby preventing break-up of the glue stream.
