Upper and lower rotating drums ( ) having shearing blades ( ) are supported by a bearing frame ( ) via eccentric sleeves ( ). Only the upper rotating drum ( ) is rotated by a drive motor 17, while the eccentric sleeves ( ) are rotated by a drive motor so that the rotating drums ( ) can be made to approach and separate from each other. Interlocking gears ( ) are fixed to shaft end portions of the rotating drums ( ) to permit interlocking of the rotating drums ( ) when these drums approach. Oldham's couplings ( ) are interposed between the interlocking gears ( ) and timing gears ( ) to rotate the rotating drums ( ) constantly and synchronously.

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.
