Strengthening means for a CRT multi-opening mask framing member

摘要

The invention is a structural improvement in the framing member of a rectangular color CRT mask-frame assembly. The improvement, which promotes rigidity in the framing member, is in the form of a continuous perimetrical channel-like indentation extending along the major and minor related elements of the framing member. The beneficial corner mergings of the respective channel-like indentations are effected by discretely shaped "S"-like arcuate channel-like formations which are oriented substantially relative to the flow of the formed material thereat.
