Abstract: A tube-bending machine including a bending arm that is provided with a jaw support that moves horizontally in a direction of a bending head, whereby said jaw support is integral with a clamping jaw assembly that comprises at least one jaw for bending a tube clockwise and at least one jaw for bending a tube counterclockwise, wherein the jaws are fixed to one another. A bending roller is fixed to the bending arm and comprises at least one jaw for bending the tube clockwise and at least one jaw for bending the tube counterclockwise, whereby said jaws of the bending roller are laterally offset relative to one another and on both sides of a vertical axis XX? of the bending head. A first strip support is also provided having at least one jaw to clamp the tube as it is being bent clockwise and a second strip support that includes at least one jaw to clamp the tube as it is being bent counterclockwise.

Abstract: An orbital machine for bending tubes includes a fixed base frame on which is displaced in translation a guiding support cooperating with a feed-off arm driven in rotation around a horizontal axis and that forms an integral unit with a bending head having two tightening semi-rollers that are driven first according to a direction opposite in direction from the axis of the tube in a plane perpendicular to that of the bending plane XX? of the tube, and secondly in rotation to achieve at least one bending on the tube, the base frame including a loading device allowing the tube to be bent to be held first in a horizontal position oriented in the direction of the bending head and secondly in a position that is fixed in rotation and in translation while the different bendings are achieved.

Abstract: The invention concerns a tube bending machine comprising a bending arm (3) provided with a jaw support (7) which moves horizontally towards the bending head (2), said jaw support (7) being integral with a clamping jaw (8) which comprises at least a jaw (9, 11) for bending the tube (4) in a clockwise direction and at least jaw (10) for bending the tube (4) in an anti-clockwise direction, said jaws being mutually fixed, a bending roller (12) which is stationary on the bending arm (3) and which comprises at least a jaw (13, 15) for bending the tube (4) in a clockwise direction and at least a jaw (14) for bending the tube (4) in an anti-clockwise direction, said jaws (13, 14 and 15) being laterally offset relative to one another and on either side of the vertical axis (XX?) of the bending head (2), a first gib support (16) which comprises at least a jaw (18, 19) for clamped accompaniment of the tube (4) when it is being bent in a clockwise direction, and a second gib support (17) which comprises at least a jaw (2

Abstract: The orbital machine for bending tubes (2) according to the present invention comprises a fixed base frame (3) on which is displaced in translation a guiding support (8) cooperating with a feed-off arm (13) driven in rotation around a horizontal axis and that forms an integral unit with a bending head (4) comprising two tightening semi-rollers (23, 24) that are driven first according to a direction opposite in direction from the axis of the tube (2) in a plane perpendicular to that of the bending plane XX? of the tube (2), and secondly in rotation to achieve at least one bending on the tube (2), said base frame (3) comprising a loading device (5) allowing the tube to be bent (2) to be held first in a horizontal position oriented in the direction of the bending head (4) and secondly in a position that is fixed in rotation and in translation while the different bendings are achieved.
