Abstract: When hot rolling metal strip, it is usual to apply tension to the strip and then a contact-type strip tension detector is employed to detect variations in tension across the width of the strip. The signals are used to adjust the rolling mill in the sense to reduce shape variations across the width substantially to zero. Until tension has been applied to the leading end of the strip, the contact-type detector cannot be used. Consequently, the strip may be of bad shape. The invention resides in employing a non-contact type strip shape detector to detect variation in shape and adjust the rolling mill until tension has been applied to the strip.
