Abstract (en)
[origin: US4826704A] In order to increase the efficiency of a coating process wherein a coating medium such as, for example, powders directed from a coating medium pressure line toward a workpiece to be coated, with the coating process also including an applied electrostatic field, a coating medium which does not adhere to the workpiece is drawn off by way of a suction channel. A flow of the emerging coating medium is bent toward the workpiece that is to be coated by providing a carrier surface profile area between an outlet of the coating medium and a suction channel. By this arrangement a flow velocity gradient between the workpiece to be coated and the profile area is realized with the resulting pressure gradient from the profiled area toward the workpiece.
