ABSTRACT:
The present invention relates to a method and apparatus of recovering ductility of a cold rolled metal strip. The metal strip is greatly bent a few times under tension along work rolls of small diameter rotating freely with extremely low friction or on fluid film of pressurized liquid in the space formed between the metal strip and a supporting guide. Thereby the stress-strain curve of the metal strip is altered, and the change results in recovering ductility of the metal strip.
