Abstract
Provided are nozzle assemblies for a spraying apparatus having an outer wall (146) having opposed inner and outer surfaces, a central aperture (136) extending through the outer wall, and a pair of auxiliary apertures (158) disposed on the outer wall (146). Each auxiliary aperture is aligned along a respective auxiliary axis (162) and areas of the inner surface (164) of the outer wall (146) adjacent to the auxiliary apertures (158) are countersunk to define ledges (166) that are axially symmetric about the auxiliary axes (162). These assemblies obviate problems associated with rotatable molding pins and also provide the unexpected advantage of providing axial alignment of the air flow profile as air is emitted from the auxiliary apertures.
