Abstract
Method and apparatus for producing large-area metal, especially steel, plates. The metal strip unwound from a coil is continuously treated by a heat treatment followed by stretch-bend leveling and then stretcher-leveling, the latter being discontinuously carried out by clamping the strip at two locations and urging those locations apart. Only subsequently is the strip cut to form the plates.
