Cold rolling method for a metal strip and a mill array

A cross-rolling mill has upper and lower work rolls which can be made to cross one another together with their respective backup rolls by moving upper and lower roll chocks in pass lines opposite to each other with upper and lower cross heads. Upper and lower gradient portions are formed at opposite inclinations at side faces of the upper cross head and the lower cross head, respectively. Wedges having upper and lower oppositely inclined surfaces slidably engage the gradient portions of the upper and lower cross heads. The upper and lower cross heads can thus be moved in opposite pass line direction by moving the inclined surfaces of the wedges upward and downward.
