  • Publication number: 20200255929
    Abstract: A method is provided for producing a foil made of an electrically conductive material. The foil consists of the same electrically conductive material along the extension of the foil thickness. A flexible substrate is first introduced into a working chamber; a layer made of the electrically conductive material is deposited on at least one surface region of the flexible substrate using a vacuum coating process; and the first layer is then removed from the flexible substrate. Either an ion-etching process is carried out at least on the surface region of the flexible substrate prior to depositing the layer made of the electrically conductive material and/or the layer made of the electrically conductive material is heated during and/or after the layer is deposited.

  • Publication number: 20200240009
    Abstract: A device for coating a band-shaped substrate within a vacuum chamber is provided. The device comprises a coating device; a cooling device with at least one convex surface area which at least partially touches the band-shaped substrate at the time of the coating; and a coil system comprising at least a supply roller, a receiving roller, and multiple guide rollers, wherein the band-shaped substrate includes an electrically conductive material at least on the side where the band-shaped substrate touches the cooling device, wherein the cooling device has an electrically conductive base body and an outer edge layer comprising an electrically insulating material; the coil system is designed to be potential-free with respect to the electrical mass of the device, and an electrical voltage of at least 10 V is formed between the electrically conductive base body, the cooling device, and the electrically conductive material of the substrate.
