The bending unit comprises a fixed counterblade (2), a metal sheet holder (3) which, pressing on counterblade (2), holds one of the edges of metal sheet (12) and a blade (1) arranged on the same side of the metal sheet holder (3) as the metal sheet (12), which, translating with respect to the counterblade and to the metal sheet holder, causes the displacement outside the plane of the edge of the metal sheet which is not held by counterblade (2) and metal sheet holder (3). Counterblade (2) and blade (1) are made in a plurality of segments (6, 4) parallel and side by side to one another in a direction orthogonal to the plane of the sheet of metal sheet (12) and the metal sheet holder (3) is so flexible as to follow said counterblade (2) in its deflections. <IMAGE> |
