1. A corrugated pipe bender composed of cams, bending rollers and guiding rollers, characterized in that the body (1) contains at least two pairs of sliding cams (3), interacting with at least two bending elements (4) equipped with bending rollers (5) and guiding rollers (6), where the bending elements (4) are mounted with articulated joints in the body (1) and the cams (3) are located in the guide rails (2), whereas the axis of rotation of the bending element (4) is shifted away from the centre of curvature of the bent pipe (8) and constitutes the centre of rotation of this part of the bent pipe (8), which is a wave made by that bending element (4).<IMAGE>
