Abstract (en)
[origin: EP1247594A2] The method for bending metal profiles in bar form is performed in a machine comprising 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. The end portion of the bars is gripped by virtue of an extraction assembly (8) 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 controlled extent, to complete the dimensions of the shaped articles to be provided, then the shaped articles are cropped to size. <IMAGE>
