Abstract (en)
[origin: EP2614901A1] Method and machine for the production of continuous bent structural sections to be used to form electro-welded lattice girders, normally used in building construction, starting from a wire or metal rod (10). The wire or the metal rod (10) is made to move forward linearly, determining the pitch of the structural section to be obtained by means of a feeding powered carriage (11) and accompanying powered carriage 16, said carriages being coordinated with each other so as to move alternatively in a reciprocally opposite direction. The wire or metal rod is engaged by a shaping arm 20 that is driven to move vertically in a curvilinear trajectory and with a travel adjustable on the basis of the height of the structural section to be obtained. The wire or metal rod is alternatively held locked and unlocked in fixed positioning point (26), downstream of the shaping arm, provided with restraining elements (27).
