Abstract: The disclosure relates to a method of bending elongated materials such as pipe by applying a compressive primary bending force to the material at locations on either end of the portion of the material to be bent and locally stimulating bending of that portion of the material by the application of heat or a secondary bending force. The end portions of the materials are engaged by clamps, each clamp having an arm extending normal to the principle axis of the material. The compressive primary bend force is applied by exerting a force on locations on the arms displaced from the principal axis of the material, which force tends to draw the ends of the arms together.

Abstract: A method of continuously bending elongated materials may comprise engaging one portion of the elongated material with a guiding means and clamping a second portion of the elongated material in a clamping device driven to rotate with a movable axis of rotation perpendicular to a horizontal plane. A heated zone bounded by a cooled zone moving relative to the elongated material may be established in the material by suitable heating and cooling means disposed adjacent to the material. The elongated member may be driven to pass through the guiding means. Where a hollow elongated material is to be bent, a compressing means may be placed within the elongated material to inhibit deformation of the cross-section of the material. An apparatus for continuously bending elongated members may be comprised of plural means for performing the aforestated functions.
