Bending machine

A bending machine for simultaneous bending of the wires of a wire mesh comprising a base, a rest supported on said base for supporting the wire mesh, bending mandrels supported on said base adjacent said rest and around which the wires of the wire mesh are bent, a bending rod for bending said wires about said mandrels supported with respect to said rest and mandrels so that the wire mesh passes between the bending rod and mandrels when supported on said rest, a bending beam, at least one support arm connecting said bending rod to said beam, at least one web member connected to said beam, two spaced bearing holes in said web member, rotational shaft bearings mounted in said holes, said bearings being positioned with respect to said mandrels so that a first line passing through the centers of rotation of said bearings is substantially parallel to a second line passing through the centers of said mandrels and bending rod, two crank members rotatably mounted on said base and having their axes of rotation lying on a third line extending parallel to said second line, a crank shaft mounted eccentrically in each crank member and engageable in one of said bearings in said web member, and said crank members being adapted to driven to operate said bending rod through an arcuate path about said mandrels through said web member, beam and support arm.
