Abstract: A machine for bending pipes (2; 63; 78) sections or similar of a given section (S1; S2; S3) has a guide device (6) having a longitudinal axis (9) for guiding the pipes (2; 63; 78) in a feed direction (D1) parallel to the axis (9); and a bending member (7) movable with respect to the guide device (6) in a plane (P1) perpendicular to the feed direction (D1), and having an annular guide (50), which has a passage section (45; 61; 76) for the pipes (2; 63; 78) substantially equal to the section (S1; S2; S3) of the pipes (2; 63; 78) and is defined by rollers (40; 52; 82; 67) rotating about respective axes (41; 53; 83; 68) lying in a plane coplanar with the passage section (45; 61; 76).

Abstract: A machine for bending sections (2) having a longitudinal axis (3) and a constant cross section along the longitudinal axis (3) feeds the sections (2) longitudinally in a first direction (D1), and has a first and a second annular die (11, 12); an ass (15) connected to the second annular die (12) and movable in a plane perpendicular to the first direction (D1) to move the second annular die (12) into a number of operating positions with respect to the first annular die (11) to bend the sections (2); and a joint (22; 39) connecting the first and the second annular die (11, 12), and which forces the second annular die (12) to assume a given position with respect to the first annular die (11) for each position assumed by the assembly (15).
