Abstract: A method and system are provided for dispensing only that amount of coating material which is required for coating a series of one or more articles to be coated by the coating material. The method and system include the step of, and apparatus for, feeding that amount of coating material to an intermediate container. The intermediate container receives the coating material from a color changer. The connection between color changer and intermediate container is so designed that no electrical current flow exists between these two components, even when using electrically conducting coating material. The coating material is electrostatically charged at an atomizer downstream from the intermediate container during a spray operation.

Abstract: A device for feeding an electrically conductive coating material from a supply system to a coating material dispensing device wherein a high electrostatic potential is maintained between the supply system and the device, comprising an intermediate storage container fillable in controlled manner from the supply system to a maximum fill level and connected to the coating material dispensing device by a coating material conduit maintained at substantially the electrostatic potential of the coating material dispensing device, a device provided in the intermediate storage container for breaking up the supply of coating material into the intermediate storage container into electrically separated individual particles, and means for coupling the breakup device to a source of coating material, the breakup device being arranged above the fill level such that, between the breakup device and the interior of the intermediate storage container, a minimum spacing is maintained so that no electrostatic discharge occurs.

Abstract: A coating material quantity control system for the coating of articles in a production line operation having a plurality of coating material dispensing devices. Each device is connected to a plurality of coating material feed lines carrying various coating materials, each associated with a separate flow control device. A program control device, upon initiation of the selection of a new coating material type, assures the sequence of the necessary changeover operations. A common control is provided for the flow control devices associated with each coating material dispensing device. The program control device also controls control parameters in each such common control for the selected coating material type, and for variations in size of that portion of the article being coated which is before a particular coating material dispensing device.
