A bending machine is provided to remove finished tubular products easily and to correct the curvature of the metal plate material when the metal plate is bent over the desired curvature. A bending machine comprises a driving roller(2) repeatedly rotating forward and reversely around a base frame(10) and a driving shaft(12) applied with driving force, an idle roller arranged corresponding to the thickness of a metal plate(P), first and second bending rollers(6,8) installed at left and right sides of the driving roller to move up and down, a bending cylinder(18) moving the idle roller and the first and second bending rollers up and down, a lift cylinder(22) moving a roller support up and down, a driving roller supporting device which supports selectively one side of the driving roller in a cantilever type, a correction part including a fist and a second correction rollers installed on one side of the metal plate contacting the driving roller surface.
