ABSTRACT:
A method is disclosed for mating the tubular cap and tubular shank of the cathode assembly used in TV CRT electron guns. The shank has an end larger in diameter than the cap, and a narrow end adapted to fit into the cap. The method comprises causing the cap to fall open-end-down into a first receptacle. The first receptacle is inverted in conjunctive alignment with a second receptacle, causing the cap to fall open-end-up into the second receptacle. The shank is then caused to fall narrow-end-down into the second receptacle and into the cap; the second receptacle is adapted to reject the larger end of the shank. The second receptacle is inverted in conjunctive alignment with the first receptacle, causing the mated cap and shank to fall shank-end-down into the first receptacle where it is held cap-side-up for further processing.
