Abstract:
An electrolytic coating installation for metallic bands, comprising:at least one electrolytic bath (12),means (16) to control the running of a metallic band (23) inside the electrolytic bath (12), along a running direction (A);at least one anode bridge (14) comprising a carrier bar in the form of a carrier beam (31) extending along a horizontal direction, transversally to the running direction of the band (23),at least one anode plate (13) comprised of a set of bars (18) arranged beside one another and each forming an anode section (18) comprising a portion (39) made of the metal to be deposited on the band (3) and soluble by electrolysis,means (19, 20) to control the sliding motion of the said bars (18) along the anode bridge (14), between a supply side and a exhaust side of the bar, for the replacement of a worn bar with a new bar,an electric supply circuit from a continuous electric current source (37') with a negative pole connected by electric contacting means (16) to the metallic band (23) for forming a cathode and positive pole,separate electric supply means displaced from each of the anode sections (18) comprising a number of live pins (32) arranged in succession along the beam (31) of the anode bridge (14), whereas the said live pins (32) are electrically isolated from one another and from the carrier bar (31),wherein the said anode sections (18) rest on the anode bridge (14) via the said pins (32) with the option of sliding along the aligned pins,wherein each live pin (32) is electrically connected to at least one of a positive pin of the current source (37') by an individual controlled switching means (35) or to at least one of an anode section (18) resting on the said live pin (32).
