Abstract
The present invention relates to a metal cathode sheet assembly for use in the electrolytic recovery of pure metals, especially copper, in an electrolysis tank. The metal cathode sheet is provided at its side edges with an edge protector formed by a grooved profile strip. The edge protector is secured to the side edge by engaging at least one trapezoidal holding wedge that has back surfaces facing away from the narrow sides. The wedge is able to be secured in a cutout on the edge. The edge protector grips behind the back surface with counter-support surfaces.
