| 摘要 | PURPOSE:To suppress the oscillation in a non-forming part and to prevent generation of torsion by providing respectively fixing parts for grasping the linear and curved parts of a reinforcing bar on the right and left of a bending part for the reinforcing bar having an angle-shaped pressing body and making changeable the spacing between the angle-shaped pressing body and the respective fixing parts. CONSTITUTION:A reinforcing bar I is grasped and fixed between a pressing body 8 of a fixing part 2 for grasping the linear part of the reinforcing bar and a stationary support 5 and if an angle-shaped pressing body 12 is advanced thereafter, the tip end thereof is curved. The curved part is then fed to a fixing part 14 for grasping the curved part of the reinforcing bar and after the curved part is grasped and fixed between a stationary support 17 and one side of an angle-shaped pressing body 26, the body 12 is advanced to bend further the bar I. The bar I is fed forward in succession to grasp and fix the curved parts at two points between the angle-shaped pressing bodies 26, 30 in the part 14 and the supports 17, 19 and thereafter the body 12 is advanced. These steps are repeated to obtain a lattice bar. The space between bases 3 and 15 is changed according to the forward and backward movement of the body 12 in each step so that the bar I is fed as required in the stage of bending. | ||||||
