Bending-shaping machine for sections and method to apply bends in the trailing end of sections

摘要

Bending-shaping machine for sections (29) as in IT-A-15904 A/89 (EP-A-379043), 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 a bending disk (11) si displaced sideways (from position 11S to position 11D or viceversa) by passing under the section (129) and thus re-positioning the abutment roll (12) in relation to the section (129).
