Installation and method for forming at least one corner region (1.0) in a rectangular metal plate (1), the corner region (1.0) being formed in the intersection between a first section (1.1) and a second section (1.2) of the metal plate (1). For forming a corner region, the bending of the first section (1.1) of the metal plate (1) is performed first, and then the bending of the second section (1.2) of said metal plate (1) is performed, at least the region of the first section (1.1) closest to the corner region (1.0) being held and kept immobile during said bending of the second section (1.2), said region of the first section (1.1) being released once said bending of the second section (1.2) has been completed.
