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.

Adjustable height self-lubricating pulley system for use with a flyer bow

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.

Flyer bow with integral enclosed wire guide

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.

A flanged bearing includes a layer of woven braid which is continuous throughout a sleeve and a flange portions thereof, with at least one braid strand substantially parallel to a bearing axis. The sleeve may be cylindrical in shape and the flange portion washer shaped, and the braid may include carbon fiber strands impregnated with a polyimide resin so that the bushing is lightweight and self-lubricating at high temperatures.
