Abstract:
An apparatus for cold bending a metal sheet to obtain an elongated article having a predetermined section profile, said apparatus comprising:support means for supporting opposite ends of the sheet to be formed;a form having a longitudinal axis and a section shaped according to said predetermined profile, said form operated perpendicularly with respect to the longitudinal axis;a stop that faces said form, so that said form, when lowered, clamps said sheet resting on said support means to said stop;two plates mounted for oscillation on a vertical plane transverse to said form;two spindles fitted to said plates and arranged parallel to said form and located at either side of said stop plate;two bending members rotatable about said spindles, means for driving said bending members in time relation with a synchronous movement of said form and said stop, such that the bending members fold the two ends of said sheet around said form.
