Abstract
Lead making apparatus has normally aligned transfer heads with conductor cutting and stripping blades therebetween. Each head is mounted on a rotatable transfer head shaft and has a slide with a clamp thereon through which wire is fed and clamped. The slides carry followers in respective first arcuate track segments which pivot to pull the slides away from each other for insulation stripping. The transfer head shafts rotate in opposite directions through ninety degrees to align stripped ends with terminating stations as the followers ride through first arcuate track segments into second arcuate track segments, each pair of track segments forming a continuous ninety degree arc of circular track. The second track segments pivot an adjustable amount to push the slides forward for inserting conductor into terminals to an adjustable degree. Transfer head shafts carry pinion gears fixed thereto against rotation and driven by a rack which reciprocates intermittently. Shafts have cylindrical tracking cams on the lower ends opposite the transfer heads, each having two circumferential tracks which contain two pairs of diametrically opposed followers on linkage which causes vertical movement …
