ABSTRACT:
Workpieces vertically suspended on carrier bars in side-by-side relation are dipped into an electrolyte bath which has a plurality of electric contact plates of alternating polarity spaced along one side. Electric energy is applied to the workpieces from the plates through the carrier bars and the successive work pieces serve as electrodes of opposite polarity, the polarities reversing as the individual carrier bars are advanced from plate to plate.
