Abstract

A process for the discontinuous spray application of a fluid comprising supplying such a fluid to a sprayhead (12), applying a controllably variable electrical field to the fluid such that at controlled field intensities the fluid can move from the sprayhead under the influence of the field to form a spray, effecting relative movement of the sprayhead (12) and a target (2), and switching the spray on and off, characterised in that the field is applied by means of constant potentials applied to the sprayhead (12) and a charged field adjusting electrode (20) and spraying only occurs when the target (2) is a desired distance from the sprayhead, and apparatus therefor.
