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).
L'invention concerne une cintreuse pour tuyaux (2, 63, 78), sections, ou analogues d'une section transversale donnée (S1; S2; S3). Ladite cintreuse comprend un dispositif de guidage (6) possédant un axe longitudinal (9) qui permet de guider les tuyaux (2, 63, 78) dans un sens d'alimentation (D1) parallèle audit axe (9); et un élément de cintrage (7) mobile dans un plan (P1) perpendiculaire au sens d'alimentation (D1) par rapport au dispositif de guidage (6), et possédant un guide annulaire (50) pourvu d'une section de passage (45, 61, 76) pour les tuyaux (2, 63, 78) sensiblement égale à la section (S1, S2, S3) desdits tuyaux (2, 63, 78), et définie par des rouleaux (40, 52, 82, 67) qui tournent respectivement autour des axes (41, 53, 83, 68) s'étendant dans un plan coplanaire à ladite section de passage (45, 61, 76).
