Abstract
A shadow mask support frame for a cathode-ray color display tube of generally rectangular shape in top plan view. The shadow mask support frame includes two end upstands, which are located opposite each other and which are intended to support a shadow mask, and two lateral upstands, which are intended to keep the end upstands apart or separated from each other. The end upstands and the lateral upstands are of generally tubular shape and constitute an almost continuous closed hollow body containing at least one plane closed line located entirely inside the hollow body and passing inside each of the end and lateral upstands. It may be produced by folding a single metal strip or by fitting two drawn shells together.
