Abstract

The method for bending metal profiles in bar form is performed in a machine that includes a line (3) for feeding the profiles in the form of bars to be bent, along which there are devices (4) for driving the bars, a cropping assembly (5) and at least one bending assembly (6). The method entails: processing the end portion of the bars by performing the advancement of the end portion of the bars by virtue of the driving devices (4), and stopping the end portion of the bars in a preset position, according to the dimensions of the shaped articles to be produced and to the fixed stroke of an extraction assembly (8). The end portion of the bars is gripped by virtue of the extraction assembly (8), which is provided with a clamp-type grip device (9) suitable to be actuated with a reciprocating motion. The end portion of the bars is then subjected to a translational motion, for an advancement stroke of fixed extent, to complete the dimensions of the shaped articles to be provided, then the shaped articles are cropped to size. <IMAGE>
