The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0030] Plates may be twisted when they are produced. Existing straightening machines only use extrusion rollers to correct plates with bulges and uneven surfaces. However, due to the structural limitations of the extrusion rollers, if the plates that are overall twisted are corrected, excessive extrusion at the twisted position may cause the plates to deform and wrinkle after correction.
