Abstract
Abstract An apparatus for bending leads axially protruding from a component includes a pair of spaced apart discs mounted on a shaft. Each disc has a plurality of generally V-shaped cutouts that are axially in registry with the cutouts on the other disc such that the component is retained in a registered pair of cutouts. The span between opposing leading and lagging surfaces defining each cutout, is related to the radius of curvature of a partially conically shaped lagging outboard edge of the cutout by a predetermined function. In other words, due to the V-shape of the cutout, the head is held at a certain radial position in the cutout between the leading and lagging surfaces of the cutout. At this radially coincidental point, the span of the cutout of course equals the diameter of the lead. The radius of curvature of the lagging outboard edge of the cutout at that radially coincidental point is made a predetermined function of the diameter of the lead, for example equal thereto. The apparatus also includes a wire bending mechanism that is disposed outboard of the component on either side of the pair of discs. A cutting mechanism may also be included mechanically upstream of the lead wire forming unit.
