Patent abstract

A braider for braiding wires to a tube comprising an iris assembly having stacked iris plates. Each of the iris plates includes a center aperture, a wire orifice disposed radially outward from the center aperture, and an arcuate channel. The iris plates are rotatable relative to each other to adjust a circumferential orientation of the wire orifices relative to each other. The arcuate channel(s) of each respective iris plate is coincident with the wire orifice(s) of the remaining iris(es). The braider comprises a feeder assembly configured for advancing the tube through the center apertures, and advancing the wires through the respective wire orifices. The braider further comprises a braiding assembly configured for braiding a plurality of filaments around the tube and the plurality of wires as they are fed through the iris assembly, thereby creating a braided tube assembly.
