Abstract
A method for treating a single side surface of a metallic strip by applying two strips back to back with an insert disposed between the strips in engagement with the back surfaces of the strips for preventing introduction of the treatment solution between the strips. The insert may be a magnetic pliable band in arrangements where the metallic strips are magnetizable, or it may be non-magnetic and provided with adhesive on its surfaces in engagement with the strip backs, or it may be held between the strips under pressure being applied to the strips forcing them toward each other.
