Abstract
An apparatus for treating metal wire by multiple reverse bending and associated methods for using the apparatus are disclosed. The first roller has a first roller diameter, is followed by N−1 intermediate rollers with intermediate roller diameters and ends with an exit roller with an exit roller diameter. The exit roller is larger than the first roller and any one roller in the sequence of rollers has a roller diameter that is not smaller than the preceding roller in the sequence. The progressively larger diameters impose a well-controlled, gradually decreasing curvature to the wire resulting in a cast controlled wire. By folding the wire path together, a compact arrangement is obtained accommodating the increasingly larger rollers. A method to operate the apparatus is also described that allows for an easy adjustment of the apparatus in function of wire thickness.
