passes through the wire twisting machine will at times break and the broken wire 50 can impact the body 80 which is rotating at a high speed in the machine the braided fiber 85 construction is more resilient to wire 50 strikes and the braided fiber 85 construction works to arrest any cracks that may be initiated due to a wire 50 strike resulting in a longer body 80 life referring again to fig5 the body 80 of the bow may also have hollow sections 86 to decrease the weight while increasing the stiffness and give it an i beam geometric shape the reduction of weight of the body 80 reduces the centrifugal pull on the airfoil body 80 attachment ends the hollow sections 86 can also be filled with foam 87 to further increase stiffness of the body 80 without adding significantly to the weight of the body 80 the thicker section that is provided by the use of an airfoil section to contain the wire guide inserts 90 and the wire 50 internally also produces a stiffer airfoil cross section this stiffer cross section enables the body to keep its as manufactured curved shape 120 even under the high centrifugal loads that are imposed on the body when it is spinning in the wire twisting machine as is depicted in fig1 a conventional designs with thinner cross sections tend to produce an irregular shape 130 and tend to flatten at the apex of the bow while rotating as shown in fig1 b the result of the irregular shape 130 is that the wire makes greater contact with the wire guides and degrades the quality of the wire due to the abrasion by the greater contact area and force while preferred embodiments have been shown and.
