Abstract
An installation for manufacturing an ultrathin foil by electrolytic deposition onto a moving cathode with eventual separation of the deposited material from the cathode is disclosed. The installation includes at least one anode having a plate perforated by a first series of orifices supplied with means of feed of electrolyte. The plate is also perforated by a second series of orifices which are suppled with means of evacuation of electrolyte. The installation of manufacturing includes the moving cathode which is comprised of a metallic belt extended taut between two parallel rolls, which are preferably horizontal. At least one of the rolls is motorized so as to cause the belt to rotate around the two rolls. A first set of the anodes is disposed facing a portion of the length of a first longitudinal run of the belt. Means of electrical connection are provided from the plate of each anode of the first set to the positive terminal of a source of continuous D.C. current. Means of electrical connection are provided from the metallic belt to the negative terminal of the source of continuous D.C. current. Means are also provided for regulating the speed of said metallic belt, the rates of…
