PURPOSE: To eliminate the limitation to the increase of a spindle diameter and to equip roll benders without interfering transmission means for spindles and intermediate rolls.

CONSTITUTION: An axial center 01 of each spindle 5H, 5L is arranged eccentrically outward before and behind the axial center O of each opposite intermediate roll 2H, 2L, above and below it, and each spindle 5H, 5L and the intermediate roll shaft part opposing it are linked and connected through gear conducting means 7H, 7L. The casings 11H, 11L of the conducting means 7H, 7L are connected by bending means 14H, 14L slidably with roll covers 10H, 10L.
