An electrode frame for the electrolytic recovery or purification of metals comprises four frame arms (1-4). It serves to tension a filter cloth arranged on both sides of the frame plane between which the interior (5) of the frame is enclosed. In order to keep constant the tension of the filter cloths, at least one (4) of the arms (1-4) is flanked by a pressure bar (6) which extends essentially parallel thereto, is spaced therefrom and is charged with spring pressure in a direction (7) leading away from the frame interior (5). |
