Abstract
Electroplating cell comprising an electrolysis tank (2) containing a plating solution (S), at least one immersed anode (3), means for making a strip run through the solution (S) in front of said anode (3), from one of its edges (3A) to the opposite edge (3B), and electrically insulating masks (4A, 4B) arranged along said edges (3A, 3B). Said masks overhang said edges by an amount at least equal to the distance separating said anode (3) from said strip and overlap them by an amount less than the same distance. Application to coating with an alloy, especially a zinc-based alloy, especially in installations having several successive cells. The quality of the coating is improved, something which facilitates the subsequent forming and painting of the coated sheet.
