PURPOSE:To realize high speed passing of wire by disposing a co-under flow device for feeding a conductor or an induction wire at the entrance port thereof. CONSTITUTION:A co-under flow feeder 11, i.e., a co-under spiral flow generator, is disposed at the entrance suction port 6 of a co-under spiral unit 3 wherein compressed air is introduced through a co-under slit 12 made through the co- under flow feeder 11 thus feeding a conductor 7 through a feeder 13 to the unit 3. In such wire passing unit, conduit connection port 8 or one unit is coupled with the suction entrance port of another unit thus constituting a multi- stage unit. The co-under flow feeder 11 is provided with an entrance port 14 having diameter slightly smaller than the diameter of the entrance suction port 6 of the co-under spiral flow unit 3 but slightly larger than the diameter of the conductor 7. |
