The threading of the tandem cold metal rolling mill is a significant function in the control of this process. During the threading process it is important to reduce the excursions in the strip thicknesses and tensions to contribute to the stability of rolling, to avoid reducing strip tension so as to preclude the throwing of a loop of strip at the entry …
