Abstract: A wire bending device includes a bending head bearing two bending tools between which the wire to be bent is passed. Either tool is alternately capable of being fixed or being a pivot for rotation of the bending head therearound. The device also includes a mechanical device for feeding the wire axially in one direction or another; a mechanical device for rotatably driving the bending tools, in two different directions, about an axis of either bending tool; and a mechanical device for shifting the bending tools in a plane perpendicular to the axis about which the bending tools can rotate. There can be calculating controller for managing simultaneously the operation of the mechanical devices, so that the movements generated by the wire and bending tools are superposed.

Abstract: A machine for bending and twisting flat metal wire for producing a motor vehicle wiper arm. The machine includes device for feeding and maintaining the wire, and at least a mechanism capable of gripping and releasing the wire in output of the feeding and maintaining device, and which is, under the action of a driver associated with a transmission device, mobile in several directions, rotating about the axis moving the wire, and moving, in one direction or another, in a direction perpendicular to the surfaces of the wire.

Abstract: A machine for high rate serial bending of a tube includes a bending head provided with a radius block and a backing block including, at the periphery, a groove with a semicircular cross-section and a driver for the backing block in rotation coaxial to the radius block, so as to drive the tube to be bent and wind it on the radius block. The radius block includes a disc including a beveled panel arranged along a chord of the disc and it includes device for moving the bending head relative to the axis of the tube along a path passing through the pins of the radius block and the backing block and a device for axially rotating the radius block independently from the displacement of the backing block.
