ABSTRACT:
This invention relates to a bead supporter for supporting a cathode assembly of an electron gun for a cathode-ray tube and fixing the assembly to a bead glass. This invention also relates to an apparatus for sorting and transporting the bead supporters in a properly oriented posture to an assembly line. The bead supporter includes a plurality of positioning projections formed on the lower side of its central portion, and cut-out portions formed in its upper edge portion opposite to the projections to permit the center of gravity of the supporter to vary depending upon its normal and reverse positions. The apparatus includes a feeding surface and a horizontal sorting surface for transferring the bead supporters. The width of the horizontal sorting surface is less than the width of the feeding surface such that each supporter having cut-out portions formed therein falls from the sorting surface when reversely positioned. The apparatus also includes a vertical sorting wall formed perpendicularly to the feeding and horizontal sorting surfaces for guiding the supporters.
