ABSTRACT:
A shaft is rotatably mounted to one end of a frame, and is provided with a work support and a bender arm. The bender arm is provided with a clamp means adapted to be moved radially of the work support. A bar-shaped material is tightly held by and between the work support and the clamp means, and the bender arm is turned on the rotatable shaft so that the material is bent along a recessed periphery of the work support while being supported thereby.
