present invention the flyer bow was operated at a speed of 1400 r p m at the same power draw required to operate the prior art flyer bow at 1000 r p m thus a speed increase of 40 was achieved with commensurate increase in productivity with the flyer bow of the present invention without increased power draw and without an increase in operating costs conversely it would be possible to operate the flyer bow of this invention at the speed of the prior art flyer bow i e 1000 r p m but at a lower power draw and a lower operating cost a flyer bow rotating at high speeds is subjected to significant load and stress therefore it must have sufficient thickness i e height from the inner surface 20 to the outer surface 22 to impart the desired rigidity to the flyer bow in accordance with the present invention it is also desired to optimize the airfoil shape to reduce drag on the flyer bow but without compromising the thickness of the flyer bow above the wire recess 26 while providing sufficient depth of recess 26 to house the wires accordingly as a general rule the ratio of the width w to the maximum height h of the flyer bow see fig2 should be in the range of 5 1 to 7 1 and the ratio of the overall height h to the maximum height h of recess 26 should be in the range of 3 1 to 5 1 it is to be noted that.
