Abstract
An arrangement for controlling the location of sprayed viscous material, in which a spray head forms a stream of the viscous material, and has at least three orifices for forming air streams. The orifices are disposed at substantially equal angles around the material stream. Air pressure is applied to the orifices, and this air pressure is controlled by a valve. The valve is adjusted proportional to the position of a plate that is positioned by a control. The spray head has at least three additional orifices that form second air streams placed symmetrically about the viscous material streams. These second air streams are directed to impinge upon the viscous material after the latter is deposited on a surface. An additional valve controls air pressure applied to the additional orifices, and this additional valve is adjusted proportional to the position of the plate.
