Abstract: A machine for attaching wire leads to cans for housing electrical components. The machine includes a plurality of split dies mounted on the spokes of a rotatable spindle for receiving and holding wire leads, and an index drive for rotatably indexing the spindle and split dies to a plurality of work stations, including a wire feed station, a wire upsetting station, a can staking station and a discharge station. At the wire feed station, a plurality of reciprocating plungers feed wire leads of predetermined length to the split dies so that one end of the wires project from the face of the split dies. At the wire upsetting station, a plurality of reciprocating punches upset and head the wire leads at a location spaced from their ends while at the can staking station a plurality of reciprocating punches feed cans having bottom holes over the headed ends of the wire leads as far as the heads and stake the ends of the wire leads to attach the leads to the cans.
