Abstract: Devices, systems and methods are disclosed which relate to a wire bending apparatus capable of both on and off-plane nose and mandrel bends. Exemplary embodiments of the present invention incorporate a center turret cluster with a plurality of radii possible, a nose-bending mandrel, and a mandrel-bending mandrel. This apparatus forms a bending head that is attached to a CNC wire bending machine. This combination allows increased flexibility in forming complex wire forms and cuts down secondary operations, such as operations from robot arms, sometimes associated with CNC wire bending. In addition, the turret cluster position in the center allows for bending support with mandrel bends or nose bending on the back side of the bending head, usually 180 degrees away from the normal bending area. This allows the manufacturing of double end-loop forms without the addition of external clamps or robotic manipulation.

Abstract: A slit fin heat exchanger is formed by wrapping slit fin tubing into a flat coil having two spaced rows of tubing. The flat coil is located on mandrels which are rotatable about spaced parallel axes with the mandrels and axes initially being in the same plane. The mandrels are rotated about their axes in opposite directions which shifts the plane in which the coil is located. The shifting of the plane of the coil moves a portion of a first row of the coil into contact with a planar portion of a platen and the second row of the coil into a nesting relationship with the portion of the first row which is in contact with the planar portion of the platen. Continued rotation of the mandrels causes folding of the portions of the coil which extends the area of nesting. The folding takes place through up to 120.degree. and the ends of the first row of the coil contacts a portion of the platen causing the formation of a knob at the end of each coil.
