Bending machine (10) and method for bending oblong metal elements (11) comprising a contrasting unit (13), a bending support (12) defining a bending plane (P) on which the oblong metal elements are positioned, and a bending unit (15), mounted mobile around the contrasting unit (13), so as to bend the oblong metal elements, in cooperation with the contrasting unit (13). The contrasting unit comprises a plurality of contrasting elements (13) of different shapes and sizes, and support and movement members (41, 42, 43, 143, 243) with which the contrasting elements (13) are associated so as to selectively position a determinate contrasting element (13) in a determinate operative bending position. Each contrasting element (13) is selectively movable between a lowered position, completely below the bending plane (P) and a raised position substantially co- planar with the bending plane (P). |
