  • Patent number: 5318683
    Abstract: The present invention provides an electrodeposition apparatus and a method for reconditioning gravure cylinders through electrodeposition. The electrodeposition apparatus includes a container for holding an ionic fluid bath and a reservoir for holding a supply of deposition material in fluid communication with the ionic fluid bath. An object, such as a gravure cylinder, is held in contact with the ionic fluid bath. Charges of opposite polarity are applied to the object and to the supply of deposition material. A barrier member and a diffusion member disposed between the supply of electrodeposition material and the object prevent contaminants from moving into contact with the object and also facilitate the dispersion of ions moving through the fluid bath between the supply of electrodeposition material and the object.
