A plate straightening machine includes upper rolls and an upper frame rotatable from an operating position, at which the upper rolls face downward, to a non-operating position, at which the upper rolls face upward. The plate straightening machine further includes a mounting plate detachably attached to the upper frame so that the mounting plate can be moved toward either side of the path, and at least one upper roll replacing stand disposed on either side of the upper frame in the non-operating position so that the upper roll replacing stand is flush with the upper frame for enabling the mounting plate to be moved between two positions on the upper frame and the upper roll replacing stand, respectively.
