a rebar fabricating machine is provided that is capable of processing either straight rod stock material or coil stock material . the rebar fabricating machine comprises a main cabinet , a horizontal power driven straightening module mounted adjacent to the upstream end of the main cabinet , a main drive module , a vertical straightening module , an encoder roll , a shear device and a bending head all mounted on the interior of the main cabinet . the main drive module includes a plurality of upper rolls each having a hydraulic cylinder attached thereto and a plurality of lower driven rolls driven by a single drive motor . the vertical straightening module includes a plurality of adjustable upper and lower straightening rolls . the horizontal straightening module is pivotally mounted on a base so that the horizontal straightening module can be selectively removed from the path of travel of the stock material . a swing up door is mounted on the main cabinet adjacent the main drive module so that when the swing up door is open , power to the hydraulic cylinder attached to each upper roll is interrupted so that the stock material cannot be fed into the fabricating machine . the entire apparatus is operated using an electronic computerized controller that connects each hydraulic cylinder through a common manifold to a single source of hydraulic pressure .
