Abstract: A flexible shoe for a bending machine which includes a pair of flexible resilient spring-like shafts. A flexible web extends between and is secured to the pair of shafts.

Abstract: A pipe bending machine is described which utilizes a cord and lattice support structure having a first end, a second end, an interior lattice framework and an exterior connecting cord which connects the periphery of the interior lattice framework. Pipe securing tie backs are secured to the support structure adjacent each of the first end and the second end. At least one pressure exerting hydraulic cylinder is secured to the support structure intermediate the first end and the second end. The hydraulic cylinder has a pressure member movable in relation to the support structure thereby exerting a bending force upon a pipe held by the pipe securing means. The bending force places the interior lattice framework in compression and the connecting cord in tension. The forces of compression and tension being off-setting thereby enabling the support structure to withstand the bending force.

Abstract: An improvement in a bending machine for elongate material consisting of a modified upper pressure member. The upper pressure member has a material contacting surface divided into a plurality of transverse segments which are movable to accommodate a bend in the material, such that the load required for the proper bending moment is distributed among all the segments.
