Abstract:
1. A method for manufacturing a spherical cage, the method comprising: providing a wire braid; inserting a spherical ball inside the wire braid; placing the wire braid and spherical ball inside a mold, which has a pair of openings, one on each of two opposite sides of the mold so that, once the wire braid and the spherical ball are placed inside the mold, the excess wire of the braid on one side of the spherical ball protrudes from one of the openings and the excess wire of the braid on the opposite side of the spherical ball protrudes from the other of the openings; trimming excess wire braid from the mold which extends through the openings beyond the mold, creating trimmed ends of the braid; forcing the trimmed ends of the braid into the openings in the mold so the trimmed ends are forced to conform to the shape of the spherical ball; heat setting the mold with the spherical ball and wire braid; removing the spherical ball and wire braid from the mold; and removing the spherical ball from the wire braid, resulting in a spherical wire cage.
