Galvanische Metallabscheidungsvorrichtung.

摘要

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. Thus, once the charges are appropriately applied to the object and the supply of deposition material, ions will be attracted to the object in uniform manner to provide a uniform layer of deposition material on the object. Additionally, restrictive filters are used to filter fluid which is added to the ionic fluid bath and to facilitate uniform dispersion of this fluid along the entire length of the fluid bath.
