Abstract
ethod and machine for bending concrete beams, wires, tubes or other material of a prismatic cross section (1) which is characterised by a bending mechanisms consisting of a central bolt (2) and a rotating bolt (3), which bolt (3) bends the material(1) relative to the central bolt (2). The two bolts (2) and (3) may be displaced under the bending plane and the rotating bolt (3) can be rotated relative to the central one (2) by 180 degrees. Simultaneously, a hook (5) transfers the material (1) to the opposite side of the central bolt (2). The two bolts (2) and (3) return to the bending plane,enclose the material (1) and bend it in the opposite direction. The machine consists of two bending mechanisms which move from the ends of the materialto be bent towards an inner point, bending the material (1) towards both sides, according to the method mentioned
