Abstract
Hot-rolled metal strip is pickled and then, before oiling and coiling, is subjected to a rolling operation of the skin-pass and/or bend-leveling type. If the strip is to be longitudinally split in half, the rollers of the skin-pass assembly--which preferably consists of two stages--may include a substantially barrel-shaped roller pair designed to impart a symmetrical cross-section to each of the two strip halves.
