Summary:Resilient supports (5) or resilient support holding plates are disposed in generally central portions of a frame (1, 2). The tension at and near the central portion of a shadow mask (3) is greater than that at the edges of the shadow mask (3). The resilient supports (5) are a combination of two or more types having substantially different spring constants. L'invention concerne des supports souples (5) ou des plaques de fixation de supports souples disposés dans des parties généralement centrales d'un cadre (1, 2). La tension au niveau et à proximité de la partie centrale d'un masque perforé (3) est supérieure à celle prévalant au niveau des bords du masque perforé (3). Les supports souples (5) sont une combinaison de deux ou plusieurs types ayant des constantes du ressort sensiblement différentes.
