Abstract

Abstract In apparatus for processing electrical components characterized as having leads extending from both ends of the body member there is provided a transport wheel which receives the components one at a time and while nested in notches in the wheel carries them to lead flattening and cutting dies where the leads are flattened to a determined degree and cut. At a later station these flattened leads are trimmed and/or shaped to the precise desired length and/or configuration.
