A method and apparatus for affixing a functional film on a panel surface having a curvature in three dimensional directions with at least one pushing roller. A pressing roller which is elastic has a shaft inside the roller. The shaft has a varied diameter of concave curvature with the largest portions at the ends of the shaft. The inner portion of the elastic roller is separated from the shaft by a clearance which is greater in the middle of the shaft. When the roller is pressed upon a three dimensional panel, the elastic roller is deformed into the clearance area and against the shaft. This permits even pressure to be applied across the panel. In a second embodiment, a main pushing roller unit may travel along the direction while pushing the functional film against the panel surface, followed by the two follow-up displacement pushing roller units which are displayed in response to the travel of the main pushing roller unit while pushing the functional film against the panel surface.

Device for manufacturing panel with functional film

A color selection electrode device mounts: a color selection electrode composed of filaments for regulating the position which an electron beam of the cathode ray tube reaches on a pair of U-shaped frame bodies between which the color selection electrode is stretched. Support pieces are provided for connecting both end portions of the pair of frame bodies and holding the frame bodies at a predetermined space. The color selection electrode is a metal electrode which is composed of, for example, a multiplicity of filaments. The support pieces are composed of an elastic material and are bent due to the load which is applied to the frame bodies, thereby shortening the distance between the frame bodies. In this state, the color selection electrode is stretched between the frame bodies and both ends thereof are welded to the frame bodies. Thereafter, when the load is removed, a predetermined tension is uniformly applied to the color selection electrode by the elastic restoring force. The pair of frame bodes may have either a large rigidity or an appropriate elasticity.
