Abstract
To permit continuous roll-off or stripping of metal in form of a ribbon, tape or foil from a rotating cathode roller or drum (3, 43) within a metal ion containing solution, the cathode roller or drum is cooled during operation and the solution of the processing liquid contains a halogen compound or a sulfur compound, for example zinc chloride, to obtain zinc in form of a ribbon, tape or foil. The cathode roller or drum is at least partly, and for example entirely submerged in the ion containing processing solution, rotatable about a horizontal or vertical axis, and the anodes (4, 44) are separated from the ion containing solution by a separating diaphragm or ion exchange membrane.
