ABSTRACT:
A pipe-bending machine has a bending table rotatable about an axis of rotation, a bending form having two opposite curved sections each defining a center of curvature, an oblong hole connecting the two centers of curvature, a retaining bolt coaxial with the axis of rotation of the table and projecting above the upper surface of the latter to engage the oblong hole, and means for shifting the bending form from one working position in which one center of curvature coincides with the axis of rotation of the table into another working position in which the other center of curvature coincides with the axis of rotation, and means for arresting the bending form in its selected working position.
