PURPOSE:To bend simultaneously plural reinforcing bars in two parts and to shorten the working time, by providing an L-shaped bending arm on a moving unit and a fixed unit, respectively, and constituting so that this arm turns along a bending die as it descends. CONSTITUTION:In case of width stop bar working of a reinforcing bar, a moving unit 1 and a fixed unit 2 are positioned, a necessary number of reinforcing bars 9 are supplied onto bending dies 61, 62. Rods R1, R2 are made to descend by operation of cylinders S1, S2. Bending arms 31, 32 press and bend downwards both end parts protruded to the outside from the bending dies 61, 62 of the reinforcing bar, by bending rolls 41, 42 of main arms 31b, 32b. Subsequently, when detaining parts 51, 52 of auxiliary arms 31a, 32a of the bending arms 31, 32 are made to press-contact with the reinforcing bar 9 of the upper face of the bending dies 61, 62, the bending rolls 41, 42 rotate and move by making the detaining parts 51, 52 a supporting point, go into the lower part of the bending dies 61, 62, and bend the reinforcing bar to a necessary shape. |
