  • Patent number: 6131432
    Abstract: A process for manufacturing a metal foil by effecting rolling with a high efficiency without making any defectively shaped product. A metal foil having a thickness of 0.2 mm or less is manufactured after a plurality of passes of cold rolling by using soft work rolls from the first pass to the pass preceding the kissing pass during which the kissing of rolls is likely to occur, using hard work rolls for carrying out the kissing pass with a reduction in thickness of over 30%, and using soft work rolls for carrying out the last, or the last two passes with a reduction of 20% or less. Judgment is made again as to the likelihood of any roll kissing when hard rolls are used, and the pressure to be applied for the kissing pass is controlled in accordance with the result of such judgment.
