Abstract

Electrodes for electrochemical treatment of metal strips, in particular for electrolytically coating metal strips, in which a plurality of spacer elements having an electrically insulating surface protrude from the electrode surface facing the strip to be treated during operation, are known. In order to devise an electrode that has a longer service life than known electrodes, the spacer elements are spacer rollers aligned in the same travel direction with respect to one another, and the roller diameter is between 20 and 60 mm.
