Abstract: One side of a metal strip forming a cathode is fed continuously at a given rate in an electrolyte past anodes supplied by respective controllable rectifiers. The strip is divided into increments of fixed length and predetermined width and coating rate. A total current for coating the increments is determined beforehand. The regulation method then includes determining the number of rectifiers to be put into operation, determining a predicted current for each rectifier by equally distributing the total current between said rectifiers to be put into operation, and determining current orders to be applied to the rectifiers to be put into operation. The method is cyclic for each side of the strip.
