Abstract

An electrolysis device for electrolytic deposition of a metal on at least one surface of the tape which has been precoated with a metal provides an electrolytic metal deposition band in which there is a first electrode for connection to a first voltage source. A tape drive is provided for moving the tape through the bath including first guide rollers defining a single loop for the tape through the bath. A second electrode is provided in the tape path and mounted to contact the tape above the entrance to the bath and over an area of the one metallized surface and is connected to a second source potential. Second guide rollers along the tape path downstream of the bath, including a second guide roller contact the metallized surface and is connected to a third source potential.
