Abstract
A method for treating a single side surface of a metallic strip, such as a steel strip, by soldering a pair of metallic strips back-to-back along their corresponding edges, preferably inserting a metallic edge insert strips between the two metallic strips at their joined edges. After appropriate treatment of the exposed surfaces of the sandwiched strips, such as dipping in a molten metallic bath, the metallic strips are separated by heating above the melting point of the solder, and peeling the metallic strips away from each other.
Claims40
A method for exposing to a treatment operation a single face of a metallic strip, said method comprising applying a first pair of ribbons of molten solder material one ribbon along each edge of a first metallic strip on one face thereof, allowing said first pair of ribbons of solder material to cool sufficiently to solidify, applying a second pair of ribbons of molten material one ribbon along each edge of a second metallic strip on one face thereof, allowing said second pair of ribbons of solder material to cool sufficiently to solidify, joining said first and second metallic strips back-to-back at the edges thereof by re-melting said ribbons of solder material and allowing said solder material to solidify, passing said joined metallic strips through a treatment station for treating the exposed faces of said joined strips, applying heat to said joined metallic strips proximate the edges thereof for melting said solder material, and peeling said metallic strips from each other.
