  • Patent number: 5300168
    Abstract: Apparatus for folding a sheet-form material in a zigzag fashion. Lower and upper guide members are provided in opposed relation in a frame. Sheet-form material is placed under tension between the upper and lower guide members. Plural lower up-and-down movable members are arranged at regular intervals on the lower guide member. Plural upper up-and-down movable members are arranged on the upper guide member at regular intervals and at positions alternate with the lower up-and-down movable members. Fold imparting members are arranged respectively at upper ends of lower up-and-down movable members and at lower ends of upper up-and-down movable members. Upper and lower up-and-down movable members are driven to move toward each other, sequentially from one end side of the upper and lower guide members and toward the other end side, to give folds to the sheet-form material.

  • Patent number: 5187857
    Abstract: 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.
