ABSTRACT:
A cut-clinch mechanism of compact structure operates on variably spaced leads of components after their insertion to clinch them directionally at an angle selectable between 90.degree. plus or minus 45.degree. to the line connecting the lead-receiving holes of a circuit board. The leads are clinched in parallel for optimum component stability, and their lengths are adjustable by shims. The movable one of each of two pairs of cutting knives pivots about an axis parallel to the board and has a configuration to wipe the cut lead thereagainst while exerting only small force tending to lift the board. For control purposes the presence of the component lead to be clinched is ascertained by the lead completing a circuit between the cooperating knives; and completion of its clinching by means of the movable knife.
