PURPOSE:To vary a straightening amt. even during operation and to improve the operation efficiency by changing the eccentric amt. of one part of straightening cylinder with the movement of the engaging piece engaging with the slanting groove of a supporting body in the case of straightening the bend of a round bar by plural rotating eccentric round type nozzle like straightening cylinders. CONSTITUTION:The bend of a drawn round bar B guided in by plural eccentric round type nozzle shape straightening cylinders 3 arranged inside a rotary body 1 is straightened. The engaging piece 40 engaging with the slanting groove 26 of an intermediate straightening cylinder supporting body 4a is fed by a connection rod 28, moved in the feeding axial line A direction and the eccentric amt. of the straightening cylinder 3 is freely changed even during operation. The movement of the connection rod 28 is effected with that of the end part 27 of an adjusting cylinder 6 engaged with the shaft 11 of the rotary body 1 engaged by a bearing 35 by varying the position of a mobile body 33 by the rotation of an adjusting shaft 32. The straightening amt. is freely changed even under operation to improve the operation efficiency of the straightening device.
