ABSTRACT:
A method and apparatus for adjusting the roll separation and roll speed of the roll stands of a tandem rolling mill so as to control the position of interstand looper arms without creating undesirable thickness changes. Each looper position is controlled by simultaneous adjustment of the roll separation and roll speed of the downstream stand, and adjustment of the roll separation of the upstream stand.
