Abstract
An arrangement for improved dispensed material bead profile control, in which a viscous material is dispensed in a stream upon a surface. The stream is transported along that surface and forms a bead of the viscous material. The bead is then confined with air streams which also reshape the profile of the bead. The material is dispensed by a nozzle which has at least two orifices in its proximity. One orifice is located at a distance from the nozzle which is greater than for the other orifice. The orifices form air streams under pressure and direct the air streams toward the material stream, as well as toward the bead formed on the surface when the material stream is transported along that surface.
