Abstract
A wire cutting and stripping blade (50) having a pair of opposing arcuate cutting edges (54, 55, 56) is arranged to function in an apparatus, such as a lead making machine, for cutting a wire (59) to length and stripping a portion of the insulation (59a) from its ends. The two arcuate cutting edges (54, 55, 56) are arranged on opposite sides of a longitudinal axis (x) of the wire cutting and stripping blade (50). Each of the arcuate cutting edges is composed of two concave segments (55, 56) and a convex segment (54), which form a single smooth cutting edge. The concave segments (56) closest to the longitudinal axis (x) are joined at a radiused vertex (57). The convex portions diverge away from the longitudinal axis in a direction away from the vertex (57) and form a lead-in for guiding and initially cutting the insulation of the wire.
