Abstract

Eine Masken-Rahmen-Kombination für eine Farbbildröhre weist einen Maskenrahmen (11) aus Eigen und eine Maske (12) aus einem Material mit kleinem Ausdehnungskoeffizienten auf, und sie ist so ausgebildet, daß
  • das Maskenhemd (13) an der Außenseite des Rahmens anliegt,
  • die Schweißpunkte (15.1 - 15.12) auf jeder der langen Seiten so gesetzt sind, daß sich jeweils ein Mittenschweißpunkt (15.12 bzw. 15.6) im wesentlichen nahe der Mitte der langen Seite und jeweils ein Außenschweißpunkt (15.11 und 15.1 bzw. 15.5 und 15.7) zu den beiden Seiten des Mittenschweißpunkts beabstandet um D/14 bis D/9 von diesem befindet, mit D = Rahmendurchmesser in der Diagonalen,
  • und das Maskenhemd zwischen den Schweißpunkten mit den genannten Abständen und benachbart zu den Außenschweißpunkten Aussparungen (17) aufweist.
Dank dieser Ausgestaltung ist die Maske einerseits so flexibel, daß sie Längenänderungsdifferenzen bei thermischen Herstellschritten elastisch ausgleichen kann, andererseits aber ausreichende Stabilität gegen mechanische Kräfte aufweist.
