Abstract:
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 as the item emerges from the wiping roller so as to direct the electrolyte only toward the perforations in the item to convey the electrolyte through the perforations in the item under pressure.
