Abstract: An adjustable height self-lubricating pulley system for use on the flyer bow of a twisting machine that twists strands. The height of the pulley can be adjusted to control the distance of the cable from the flyer bow during the cable's path along the flyer bow by selectively mounting the pulley spindle in one of a plurality of apertures in a pair of side plates of the pulley. The pulley is self-lubricating by virtue of the pulley spindle being coated with a self-lubricating liner system including polytetrafluoroethylene and other fillers in a resin system.

Abstract: An exemplary embodiment of the present invention is a flyer bow having a first surface and a second surface in opposition to the first surface. The first and second surfaces are joined to form an airfoil shape. A channel passes through the flyer bow between the first and second surface and a wire guide is disposed within the channel. There is at least one orifice through one of the first and second surface thereby establishing fluid communication between the channel and the ambient atmosphere.

Abstract: A flexible coupling comprised of one or more flex frames connected in series between end fittings has the legs of its flex frames so dimensioned as to provide the coupling with a uniform bending stiffness with respect to bending moments in planes at all angles to the rotational axis. This is achieved by having each flex frame itself be of uniform bending stiffness with the other coupling components designed so as to have substantially no influence on the coupling's bending characteristics, or by using in the coupling at least one "compensator" flex frame specifically dimensioned to have a non-uniform bending stiffness compensating the non-uniform bending stiffnesses of the other coupling components.

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.

Abstract: A light-weight push, pull and/or torsion rod includes a light-weight core, fittings on either end, pins protruding from the outer surface of each fitting, and a tubular strength member surrounding the core and overlapping much of the end fitting. The strength member includes a fibrous braided layer which overlaps and closely captures the protruding tips of the pins to anchor the strength member to the end fitting. In one embodiment, the end fittings are conically tapered from the side adjacent the core and flare out from the narrow end of the cone, and the braid is woven tightly around the conical portion and flared portion of each end fitting so that the strength member abuts or bears against the end fitting when the rod is exposed to tension or compression forces.
