Abstract
Leads of a leaded component are straightened by bending the leads outward past the yield point of the lead material, and then bending the leads inward past the yield. In a particular arrangement, a component rests with the lower or outer ends of the leads in transverse grooves in sliding members. The sliding members are moved outward, bending the leads outward. The component is then pushed up between comb members having inner end surfaces with ribs and grooves. The leads move up in the grooves and are bent inward.

An apparatus for straightening leads on all sides of a rectangular plan form leaded component, comprising:
- lead bending members for each respective side of said component, each lead bending member slidably mounted for reciprocal movement in a direction normal to a respective side of said component;
- a groove formed in each member extending parallel to the respective side of said component;
- means for positioning the leaded component above said lead bending members with lower ends of said leads positioned in said grooves;
- means for sliding said members outward relative to said component in order to bend said leads outward beyond a yield point of the lead material;
- and
- means for bending all the leads on all respective sides of said component back inward past said yield point.
A method of straightening the leads of a leaded component, comprising:
- positioning outer ends of said leads in a groove in each of a plurality of slidable members, a slidable member positioned for each peripheral side of the component;
- sliding said slidable member so as to bend the leads outward beyond a yield point of the lead material;
- and bending the leads back inward to a predetermined position beyond the yield point of the lead material.
