ABSTRACT:
A backplane (22) supporting a plurality of pins (21) is supported in a fixture (84) which is mounted on a movable platform (51). A pair of straightening bars (82 and 83) are attached to a movable holding bar (76) above the backplane-supported pins (21) and are spaced at least a distance equal to the spacing between alternate rows of the pins. The straightening bars (82 and 83) are positioned to capture the tips of alternate rows of pins (21). The fixture (84) is then reciprocated in a first direction and then in a second direction to process the pins (21) through a single straightening cycle. Eventually, the straightening bars (82 and 83) and all of the rows of pins (21) are processed in a similar fashion whereby each of the pair of bars processes each row of pins through a single straightening cycle. In this manner, each pin (21) is processed ultimately through two straightening cycles.
