Abstract
PURPOSE: To avoid the distortion for the circumferenc of the shadow mask and the side wall of the mask frame, without giving dispersion to the curvature of the shadow mask, by shifting the sectors toward the shadow mask through the sectioning of the lower depression tool.
CONSTITUTION: First, the lower side depression tool 11 is not extended toward the opposing direction, but held at the condition shown in the solid lines. With this condition, the mask frame 4 is placed at the spring pin holder 3. After that, the lower depression tool 11 is extended to the diagonal direction so that the side wall inside of the mask frame 4 and the side wall external part of the lower side depression tool 11 are contacted via the elastic substance 15. Then, the shadow mask 1 is placed at the lower depression tool 11, and the shadow mask 1 and the mask frame 4 are fixed by welding with the soldering rod through the upper depression tool 13 fixed with depression.
