摘要
The invention relates to an apparatus and method of controlling the generation of somewhat-to-highly viscous fluid fibers, droplets and combinations of the same, including hot melt adhesive and other fluids, that comprises, spraying a stream of such pressurized fluid through a fine orifice and along a predetermined direction in free flight, and simultaneously funneling a cone of pressurized air symmetrically about and against said stream, intersecting the same in its free flight below said orifice to control the nature, dimensions and pattern of the resulting fluid coating on surface disposed therebelow. Supplemental air controls are also providable for contouring and other effects.
