(57) 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.
