1. A flyer bow for twisting wires, said flyer bow having:
- an elongate arcuate body having an elongate center portion and first and second end portions at opposite ends of said center portion;
said center portion having an inner surface and an outer surface, each of said inner and outer surfaces being exposed to the ambient air in which the flyer bow is to operate;
at least one of said inner and outer surfaces having a curved shape forming an airfoil in cross section;
a first wire receiving recess in said inner surface to receive therein wires to be twisted;
a second recess in said inner surface, said second recess spanning and being shallower than said wire receiving recess; and
a wear strip in said second recess and conforming to said wire receiving recess.

Abstract
A flyer bow is presented for use with twisting machines to twist wires. The flyer bow has inner and outer surfaces, and at least one surface is curved to form an airfoil in cross section. The curved surface may be the outer surface or the inner surface. Both surfaces may be curved to form a symmetric airfoil. The inner surface has a wire receiving recess and a wear strip recess spanning the wire receiving recess. Aerodynamically shaped wire guides may be attached to the inner surface opposite to the wire receiving recess.

11. A wire guide for a flyer bow, said wire guide being generally arcuate in shape and having:
-
an aerodynamic shaped low profile body, flaired front and rear portions relative to the intended direction of travel of a flyer bow, each of which front and rear portions converges to a point; and two inclined sides along its arcuate length, said sides meeting to form a center line along substantially the full arcuate length of the wire guide from said front portion to said rear portion. - View Dependent Claims (12, 13)
