Abstract (en)
[origin: EP1032016A1] The support frame for a planar mask pertaining to a cathodic colour display tube, which is generally rectangular in shape, comprises two vertical end members (41,41') that are placed opposite each other and can receive a planar mask, in addition to two side members (40,40') that keep the vertical end members separate from each other. The vertical end members and the side members are generally tubular in shape and are assembled in such a way as to constitute a practically continuous hollow body, whereby it is possible to define a closed planar line that is located fully inside the hollow body and passes inside each vertical end and side member. The inventive support frame can be made by folding a single metal strip or by interlocking two pressed casting moulds. The production method involves folding.
