ABSTRACT:
The invention relates to an installation for coating a metallic band by guiding the latter through an electrolytic bath (12), while passing in front of at least one anode plate (13) constituted of a set of bars arranged beside one another along a direction transversal to the forward direction (A) of the band (23) and carried by an anode bridge (14), whereas each bar forms an anode section (18). According to the invention, each anode bridge (14) comprises a carrier beam (31) along which have been arragned, one after the other, a number of live pins (32) isolated electrically from one another and linked separately to the source of current by an individual switching device (35), in order to enable fractional electric power supply of each of the anode sections (18).
