ABSTRACT:
The equipment for preparing for electrostatic painting three-dimensional articles (P) with a predominantly flat extension, made from dielectric or low-conductivity material, which move on and are supported by a horizontal conveyor (T), presents the feature that the conveyor is made from an electrically insulating material, having a resistivity greater than that of the panels (P) to be painted. One or more electrodes (E,12) are placed in isolated positions, at suitable distances from each other and from the edges of the panels, under the said panels, at least while the powdered paints electrostatically charged to an electrical potential are being fed on to them. The electrodes emit an electrical field with characteristics such that it charges the whole visible surface of the said panels, as far as their area of contact with the conveyor, to an electrical potential of opposite sign to that of the powdered paints, in such a way that the powdered paints completely and uniformly cover the said visible surface of the panels.
