    • PROBLEM TO BE SOLVED: To reduce a working time and cost for straightening of a web angle, reducing a deviation of the web angle in a work to be straightened as far as possible, by installing at least two or more sets of rolls in parallel to web guide rolls which pinch, support and guide the lowest end of the web of the work, as well as by charging or discharging the work in a horizontal state into or out of a straightening unit with vertically movable charging or discharging conveyors.
      SOLUTION: On both sides of each right and left upper roll 2, that is front and back sides in terms of a transfer direction of the work a, the web guide rolls 4, which pinch, support and guide the lowest end of the web c of the work a, are arranged facing each other retractably and movably upward and downward. At least two or more sets of rolls 41 are also installed at the head of each web guide roll in parallel in the front and back sides of the transfer direction of the work a, as well as the charging conveyor 5 and the discharging conveyor 6 are prepared movably in the vertical direction.

    • PROBLEM TO BE SOLVED: To prevent occurrence of a roll mark by applying a swing mechanism to right and left upper rolls, which can press a flange surface to be straightened while keeping rotating circumferential surfaces of the right and left upper rolls constantly in a parallel state to the flange surface.
      SOLUTION: Bearing boards to support one end of rotational shaft of each right and left upper roll 2 are prepared respectively. Shaft pins parallel to an inserting direction of a work a to be straightened are attached respectively to head ends of supporting frames 22 for each right and left upper roll. Each bearing board supporting upper roll 2 rotatively is attached to the head end of each upper roll supporting frame via the shaft pin so that each bearing board can rotate around an axis of each shaft pin.
