ABSTRACT:
A flatpack lead forming, cutting, and straightening machine. The flatpack is unloaded from the carrier and aligned for later processing by its leads, rather than the body portion. The first processing step forms the lead by bending them downwardly against an anvil, and then bending them outwardly to form the foot. The leads are cut by an upwardly-moving cutter to prevent downward flagging of the leads. The flatpack is then placed between two vertically mounted plates such that one set of plates contacts a pair of leads disposed on opposite sides of the flatpack body. The plates are moved upwardly and downwardly to flex the leads and remove the set therein. Adjacent lead pairs are flexed 180 degrees out of phase in this process. The formed, cut, and straightened flatpack is then loaded into a handling tube for storage or transport to the assembly area. A transport mechanism transports the flatpack from each stage of the process to the next stage.
