Twisting machine flyer bow

A machine for twisting communication conductors together including in combination means for supplying the conductors to a twisting zone, a flyer that rotates about a longitudinal axis at the twisting zone, said flyer comprising a first guide at an upstream end of the flyer and around which the wires pass to a direction at an acute angle to the axis of rotation of the flyer, a second guide at a downstream end of the flyer and around which the wires are brought back into line with the axis of rotation of the flyer, means for advancing the wire under tension, a flyer bow extending along a generally arcuate path between the guides and having orbital movement around the axis of rotation of the flyer, the bow having one face which is the part of the bow that is closest to the axis of rotation, said face having a groove therein, extending lengthwise thereof, and which is a recessed part of said face and which is open to the ambient atmosphere, and with which the wires are held in contact by centrifugal force during their travel from one end of the flyer to the other during operation of the machine, and the groove being deep enough for the wires to nest therein and be shielded from the windage caused by the orbital movement of the bow whereby the wires remain in contact with the bow and protected from displacement and looping caused by transverse windage when the flyer is rotating.
