Abstract
Wire is straightened as an incident to being pulled through axially spaced upstream, intermediate and downstream straightening dies carried within a rotating arbor. Each die is formed with a groove which is specially shaped to cause the wire to tend to follow its natural path as the wire is straightened, the shape of the grooves reducing high stress concentrations on the dies and increasing the service life thereof.
