Zusammenfassung:	Cathode-ray tube comprising a color-selection frame/mask assembly, the mask being held under tension by being welded onto the ends of the long sides of the frame, the frame/mask assembly (19, 8) being suspended within the tube with the aid of support means (10) capable of serving to augment the mechanical rigidity of the sides (7) onto which these supports are welded and to cause the long sides (9) of the frame to approach closer to each other during the phases of manufacture at high temperature.
