Abstract (en)
[origin: US4849083A] A rotary conductor roll intended to be partially immersed in an electrolyte in a manufacturing line for continuously electroplating a strip (2), the roll includes, on its periphery, at least one electrically conductive active zone (3) and at least one coated zone (41) coated with a flexible material which may optionally be associated with an adhesive and which serves to seal the contact between the strip (2) and the conductive active zone (3) from the electrolyte. At least one intermediate ring (42) is interposed between said conductive active zone (3) and said coated zone (41), said intermediate ring being made of a polymer for which at least one of the following coefficients is intermediate in value between the corresponding coefficients of the material constituting the conductive active zone (3) and of the material constituting said coated zone (41), said coefficients being: coefficient of expansion, flexibility, and swelling due to contact with the electrolyte, e.g. by absorption or by chemical combination.
