Abstract

A foam generating nozzle is provided for converting a liquid containing a gas maintained under pressure in solution in the liquid, to a foam for application to a substrate. Complete foaming of the solution is accomplished prior to discharge from the nozzle. This assures in some applications complete atomization before contact with the substance to be coated.
