Method of and apparatus for somewhat-to-highly viscous fluid spraying for fiber or filament generation, controlled droplet generation, and combinations of fiber and droplet generation, intermittent and continuous, and for air-controlling spray deposition

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