Bending-shaping machine for sections (29) in which a drawing unit (10) located downstream of a bending unit (35) and on the same axis as the section (29) takes up not only a retracted position (10B) and a normal working position (10L) but also a high position (10A) to lift the section (129) above an abutment roll (12). Method for the automatic bending of the trailing end of sections (29) in a bending-shaping machine as above described, in which so as to invert the orientation of a bend (26) when making bends (26) in the trailing end (C) of a section (129), the drawing unit (10) moves from its working position (10L) to its high position (10A) and returns to its working position (10L) while bending disk is displaced sideways by passing under the section and thus re-positioning the abutment roll in relation to the section.
