Method and mechanism for producing three-dimesional clips (1a-1e) with two converging legs (4,5) from concrete rod, wire or other suitable material, of any cross-section, wherein first we produce a planar clip (9) with parallel legs by crating two bends by means of a bending mechanism (19), then by using a mechanism (19), then by using a mechanism (25) - positioned immediately after the bending mechanism (19) - consisting of an arm (16) that can reciprocate by means of a suitable mechanism (18)and has a hook (17) as its end, we entrap by the hook (17) the free leg (5) of the planar clip (9)and pull it towards the opposite leg (4), covering a suitable distance, and then we create the third dimension, bending simultaneously at the points (12,13) by a suitable bending mechanism (22), which is arranged after the mechanism (25). |
