Cold rolling method for a metal strip and a mill array

An apparatus for changing the direction of travel of a web-like material without inverting the front and rear surfaces of the web-like material is improved in that a plurality of guide rotors are disposed on each of a plurality of spiral curves along an imaginary conical surface so as to be rotatable about axes intersecting at right angles with the corresponding spiral curve on the imaginary conical surface, and a conical surface formed by an enveloping surface of these guide rotors is used as a traveling path of the web-like material, whereby shortcomings inherent in such apparatus in the prior art can be eliminated.

A tandem rolling mill train for rolling metal plate or sheet includes a plurality of crossed-roll type rolling mill stands. The work rolls on at least two of the crossed-roll type rolling mill stands are respectively slanted in opposite directions so that the widthwise shear deformation developed on the upstream crossed-roll type stand is reduced by the widthwise shear deformation caused on the downstream crossed-roll type stand.
