Patent number: 5187857Abstract: The invention provides a novel apparatus for manufacturing electronic parts each incorporating a plurality of lead wires fully wrapped with conductive foil like noise filters for example. A turn table is intermittently shifted from the first work station to the seventh work station in the state in which an individual-unit lead-wire member is retained by a holding unit on the turn table. A predetermined lead wire is folded by respective work stations, whereas the remaining lead wires are adhered with conductive foil tapes via spot-welding process, and then these lead wires are fully wrapped with conductive foil tapes. Next, the predetermined lead wire is restored to the initial posture, and then all the lead wires are fully wrapped with insulation tapes. In this way, all the lead wires are properly processed so that they can be integrated in perfect alignment with constant pitches.Type: GrantFiled: March 27, 1992Date of Patent: February 23, 1993Assignees: Hitachi Zosen Corporation, Takeshi IkedaInventors: Akira Nakao, Toyofusa Endo, Takeshi Ikeda
