The normally all-manual process for assembling wire matrix printheads may be facilitated and improved by the apparatus and associated wire insertion technique described here. Referring to the various views in Figs. 1-3, an operator manually inserts a printhead carrier 1 into part holder 2 and pushes the holder back against a positive stop (not shown) which positions it for wire insertion. Cylinder 3 is then activated to move slide 4 into the pickup position of a wire magazine (not shown) holding a supply of carbide wire missiles. Each wire missle consists of a carbide wire .012" in diameter joined by an impact head 0.110" in diameter by 0.270" in length. The overall wire length is 4.62". The wire missle is picked up by the impact head with its narrow end facing the printhead carrier and securely held by chuck 5.
