ABSTRACT:
An apparatus for processing wire or rods includes a plurality of driven fixed rollers for feeding the wire or rod through the apparatus, each fixed roller having an axis of rotation normal to the central access of the wire rod. A plurality of adjustable rollers is provided for engaging the wire rod and imparting a plastic deformation thereto. Each adjustable roller has an axis of rotation and the adjustable rollers are offset from the fixed rollers. A device is provided for moving the adjustable rollers from a position out of engagement with the wire rod to a position engaging the wire rod. A device is also provided for independently adjusting the adjustable rollers so that the planes defined by the axis of rotation of the adjustable rollers are set at an adjustable angle to the central axis of the wire rod so that a desired torsion can be applied to the wire rod. A wire bending device is also provided for bending the wire or rod, and a cutter is provided for cutting the wire or rod.
