Abstract
An electrostatic coating system in which the workpiece to be coated is charged to a high DC potential. A conveyor moves the workpiece through the coating zone past a charged conductor. A suspended workpiece support includes a swivel joint to accommodate tilt and sway of the workpiece. A charge collector on the support has a spherically contoured surface which swings from the swivel joint so that the spacing of the collector from the conductor is substantially constant, stabilizing the voltage induced on the workpiece and minimizing the danger of sparking.
