Abstract: An apparatus and method for making continuous, elongated strips or webs, of electrically conductive, flexible material having individual and successive deposits, or patches, spaced apart therealong, each deposit comprising a cathode layer on one face of the strip, oppositely disposed to an anode layer on the other face of the strip, characterized by the layers being in exact peripheral registration with each other.The registration is obtained by reverse roll coating a first such layer on the advancing strip in a first zone so that it extends above the surface of the strip, then training the advancing strip around a roll, in a coating roll nip, with the first layer down and supported on the roll surface and simultaneously reverse roll coating the second such layer on the exposed face of the strip in said nip, while the portions thereof surrounding the raised first layer are flexed out of the plane of the strip, thereby permitting the first layer to control the deposit of the second layer to register therewith.
