27412-8 ABSTRACT A pipebending machine has a forming bench that can pivot about a shaft and a forming table having a bending template and a clamp jaw that can be moved relative to this, a movable feed block incorporating a rotatable chuck. The bending template and the clamping jaw having clamping elements with complementary clamping surfaces that are matched to the pipe that is to be bent, these being spatially separated and movable into the working position. One clamping element has a clamping surface that incorporates a plurality of clamping contours for the pipe section that is to be secured, whereas the clamping surface of the other clamp element has only one clamping contour that corresponds to the contour of the pipe section that is to be bent, and thus encompasses the pipe section that is to be bent over its full surface on the associated adjoining side, through an angle of 180°.
