    Abstract: An electrostatic coating apparatus is described comprising an applicator, means for supplying liquid to the applicator at a controlled rate, means for establishing an electrostatic field between the applicator and a target substrate to be coated and control means providing an output signal to the liquid supply means for setting the rate at which liquid is supplied to the applicator, the said control means also providing an output signal to the field establishing means which, in operation, sets the magnitude of the applied field, the said output signals being such that the applied field is varied in accordance with any change in the rate of supply of liquid to the applicator.

    Abstract: An electrostatic blade is disclosed having a slot (16) extending the length of the blade and leading from a central duct (14) to an outlet (18). A surface (20) made of non-conductive material extends in front of the outlet (18) and terminates in a discharge edge (22) which is spaced 0.05 to 4mm from the slot outlet (18). In use, liquid is passed from the duct (14) along the slot (16) to the outlet (18) where it collects as a bead. An electrostatic field is applied between the liquid at the slot outlet (19) and the object to be coated which draws liquid along the non-conductive surface (20) in a tapering stream and further causing the liquid to be discharged from the edge (22). Because the stream of liquid reaching the discharge edge is very thin, very low liquid discharge rates can be achieved while still maintaining a uniform coating on the target object.
