Since the two working roll transverse shifting cylinders 202 are symmetrically arranged on the opposite sides of the working roll driving side bearing seat 201 along the Y-axis direction relative to the working roll mounting hole, when the two working roll transverse shifting cylinders 202 synchronously apply force to the working roll driving side bearing seat 201, the force on the working roll driving side bearing seat 201 is relatively uniform, thereby achieving stable transverse shift of the working roll 500.
