ABSTRACT:
A beading apparatus for an electron gun assembly having a plurality of self-indexing insulating support rods with a plurality of indexing cavities formed in a surface thereof comprises at least two bead blocks. Each of the bead blocks has a beading support surface with a plurality of apertures formed therein. An indexing pin is disposed in each of the apertures. Each of the indexing pins has a reference end which extends beyond the beading support surface and projects into the indexing cavities of the insulating support rods. A vacuum is applied to the support rods to retain the support rods in contact with the indexing pins. In a second embodiment a support foot is used in conjunction with the vacuum to retain the support rods in contact with the indexing pins.
