Abstract
A straightening apparatus includes a primary plate, a movable plate, upper and lower pressing wheels and a guiding wheel. The movable plate is movable relative to the primary plate between an open position and a closed position. The upper pressing wheels are connected to the movable plate. The lower pressing wheels are connected to the primary plate. The guiding wheel is connected to the primary plate. The upper pressing wheels are located closer to the lower pressing wheels in the closed position than the open position. The tube can be located between the upper and lower pressing wheels in the open position. The upper and lower wheels together provide a straightening passage for straightening the tube in the closed position. The tube is pressed by the guiding wheel before the tube is straightened in the straightening passage.
