Abstract
Applicator nozzles for applying a band of liquid composition e.g. hot melt adhesive to a workpiece using a hand-held applicator have been unsuitable for some purposes. By this invention a nozzle is provided comprising a resiliently flexible applicator portion terminating in a spreading lip of triangular section, bounding a depression and having an orifice e.g. cruciform in shape, opening into the depression, through which orifice material to be applied is supplied to provide a reservoir of composition in the depression. In a preferred nozzle the lip is defined by a frusto-conical outer surface and a surface of the depression meeting at an effectively circular spreading edge portion. In use the nozzle is placed on a workpiece the reservoir of composition forming a pool on the workpiece, the nozzle axis being tilted so that only a trailing edge of the lip contacts the workpiece as composition is applied.
