ABSTRACT:
A method of making a mask arrangement including two (2) or more of masks for a mask-focusing color picture tube and the mask arrangement formed by the method. A plurality of apertured flat masks, each mask comprising an effective portion having apertures and a non-effective portion surrounding the effective portion, are prepared. The flat masks are aligned and stacked, then filling material is poured into the apertures. The filling material is solidified thereby fixing the flat masks together. The fixed masks are pressed into a predetermined curved shape. Then, the filling material is removed from the apertures and the masks are separated.
