A process for electrolytically processing a flat perforated item, comprising the steps of: moving the item in a transport direction to a treatment station where the item is contacted with an electrolyte, continuously mechanically wiping, in the presence of one of a cathodic item and an anode, and an anodic item and a cathode, a surface of the item using means for reducing the thickness of a diffusion layer depleted in metal ions adjacent the surface of the item, which means include a wiping roller extending perpendicular to the transport direction over the entire width of the item and in contact with the item; and moving the electrolyte in a direction substantially perpendicular to a plane of the item so as to direct the electrolyte only toward the perforations in the item and to convey the electrolyte through the in the item under pressure.
