Abstract

The present invention concerns an apparatus and the relative process for the electrophoretic painting of metal structures (29), in particular for the electrophoretic painting of metal sheet coils. The counter-electrodes (3,20) dipped into the electrophoretic bath have a main element (21) (for instance a plate) on which holes (22) are provided, associated with groups of points (23). With the new counter-electrodes an uniform electric field is obtained on the entire coil surface, thus obtaining a constant thickness of the protective coat (ca. 3 mu m). <IMAGE>
