Abstract (en)
[origin: WO2004035241A2] The invention relates to a device for free three-dimensional profile forming, said profile having any overall dimensions but remaining constant with respect to the length thereon, especially for hollow profile. The inventive three-dimensional forming consists in bending the profile (7) along the longitudinal axis (L) thereof and displacing said profile in the direction of feed motion (V) parallel to the axis (L) with the aid of a feeding device (3) provided with a rotary drive, passing the profile through the passageway (1c) of a guiding element (1) adjacent to the profile surface and through a bending tool (5) arranged in a supporting element (4) after the guiding element (1) in the direction of feed motion (V). The bending tool (5) rotates around an axis which is perpendicular with respect to the longitudinal axis (L) of the profile (7) in such a way that it produces a bending force thereon. Said invention is characterised in that when the profile (7) rotates around the longitudinal axis (L) thereof during the displacement to the feeding device (3), the guiding element (1) and the bending tool (5) rotate together with said profile in such a way that it makes it possible to carry out the three-dimensional bending of the profile (7) even if it has a non-circular cross section.
