The electrolysis cathode may be connected to a current source in common with an anode in a galvanic bath for carrying out a galvanic electrolysis. The electrolysis cathode is embodied as a transverse support, arranged above the galvanic bath for electrical connection with at least one supply rail and a cathode made of metal, which may be dipped in the galvanic bath. The cathode sheet is embodied with a rolling direction essentially parallel to a longitudinal axis of the transverse support.
