Abstract

Disclosed are methods and apparatus for spraying liquid compositions by airless spray techniques so as to obtain wider spray patterns without having to alter the construction or configuration of conventional nozzles, nozzle tips or spray guns. By means of the present disclosure, the width of a spray pattern may be changed while the spraying operation is being conducted.
