To achieve the above object, a pair of top work roll chock,and top backup roll chock,are fixed by operating hydraulic cylinders,and,on the delivery side in synchronism to move pressing members,and,in the direction of delivery side to the position for positioning and by moving pressing members,and,on the entrance side in the direction of delivery side by hydraulic cylinders,and,on the entrance side to press the chocks,and,on the pressing members,and,on the delivery side. A pair of bottom work roll chock,and bottom backup chock,are positioned on the entrance side and fixed by operating hydraulic cylinders,and,in the opposite direction (entrance direction). Thus, the top pair and the bottom pair are pair crossed.
