Abstract
Abstract A semiautomatic machine which cuts flat metal strip or wire transversely into blanks, bends the blanks into C-shaped connectors, and clinches the connectors about wires inserted in a die for conductively connecting the wires. Wires as small as 0.001 inch can be spliced effectively. The operator''s intervention is limited to insertion of the wires into the die, and the closing of a switch for each splice to be made.
