Abstract:
1. Apparatus for the superficial electrolytic treatment of metal strips comprising a plurality of separated and non communicating containers internally defining a longitudinal feed path of metal strip ( 13 ), a plurality of electrode pairs ( 14 ′, 15 ′ 14 ″, 15 ″, 14 ′″, 15 ′″) situated along said path, whereby each electrode is associated with one of said containers ( 2 ′, 2 ″, 2 ′″) the first electrode ( 14 ′; 14 ″; 14 ′″) of each electrode pair r being located above said metal strip and the respective second electrode ( 15 ′, 15 ″, 15 ′″) of said electrode pair being located below said metal strip ( 13 ) in a reciprocally opposite position and at a predetermined distance from said metal strip ( 13 ), each of said electrode pairs having polarity opposite to that of the adjacent pair and being associated respectively with one of said containers ( 2 ′, 2 ″, 2 ″) characterised in that a) there is provided at least one pair of pressure rollers ( b) said electrodes pairs ( c) each electrode pair is provided at both ends with nozzles in pairs (
