  • Plate width adjusting apparatus and plate width adjusting method
    Patent number: 6615634
    Abstract: A plate width adjusting apparatus 1 for adjusting a strip 53 for a predetermined plate width, which is installed on a production line for the strip 53, is provided with bridle rolls 2 and 3. The bridle rolls 2 and 3 give tension in the transfer direction to the strip 53 being transferred on the production line to elongate the strip 53 in the transfer direction, by which the plate width of the strip 53 is adjusted.
    Type: Grant
    Filed: June 8, 2001
    Date of Patent: September 9, 2003
    Assignee: Mitsubishi Heavy Industries, Ltd.
    Inventors: Tetsuya Shinkai, Kensuke Fujimura, Haruhisa Sugimoto
