Abstract

There is described a device for electrolytically depositing, in a continuous operation and under a high current density, a lining metal layer over at least the one surface of a metal strip moving through an electrolytic bath, comprising at least one conducting roller cooperating with a cathode current supply, extending cross-wise relative to the strip movement direction and rotating about the axis thereof, in contact with the strip, substantially at the same circumferential speed as the traversing speed thereof, at least one anode being provided in the electrolytic bath facing at least the one surface of the strip moving through said bath, device in which said conducting roller is at least partly hollow, and the cathode current supply comprises a series of parallel-connected contacts which are distributed over that inner cylinder-like surface of the roller which lies opposite that outer surface portion the strip is applied on.
