Abstract
A system for adjusting the flow rate of charged particulate coating material between a device for dispensing the coating material and an article, or 'target,' to be coated by such material to account for factors, such as variations in the profile or contour of the target, or movement of the target transversely to the direction of motion of a conveyor upon which the target is being conveyed past the device or head, which might otherwise cause variations in the thickness of the coating material. The particles migrate in a known manner under the influence of an electrical field toward the target for deposition on the target to coat it at high deposition efficiency. The system continuously monitors the current flow to the target. The system feeds back this current flow related signal to a coating material flow rate servomechanism.
