Abstract

A method for automatically bending metal profiled elements, particularly iron rods for reinforced concrete, consisting in feeding the profiled elements (2) to be cropped along a feed line (3), in order to bend a front end (2a) of the profiled elements in a first bending position arranged along the feed line. The advancement of the profiled elements is then actuated in order to make their front part rest on a guiding channel (16), and then the profiled elements (2) are cropped to a length which also includes the rear part to be bent. The rear part of the cropped profiled elements is shifted into a second bending position which lies above the feed line (3), by a limited extent which is sufficient to move past the space occupied by the mechanical elements arranged to the rear of the first bending position. Finally, the profiled elements are subjected to a measured longitudinal movement and a rear end (2b) of the profiled elements is bent in the second upper bending position.
