| Zusammenfassung: | PROBLEM TO BE SOLVED: To easily adjust a tension difference in AG tension in a manufacturing method of an interdigital grating-like aperture grille being a color selecting mechanism used, for example, in a Trinitron system color cathode-ray tube. SOLUTION: This manufacturing method of the aperture grille in the cathode- ray tube stretches a color selecting mask 1 by pressing a frame after applying a friction coefficient conditioner for changing the friction coefficient between the frame and a pressing means for the frame to the surface of the frame 2 being a support frame in the aperture grille 3. |
