Abstract

In a rolling mill train having several successive stands, at least one stand functions according to a predetermined characteristic speed, means for providing the characteristic speed are provided at each stand and for measuring strip thickness as it leaves each stand, and means for reacting to the thickness error as a function of the desired thickness on leaving the last stand so that the functional speed of at least one stand upstream of the last is controlled while the functional speed of the last stand is maintained at the predetermined characteristic speed.
