Method of manufacturing a magnetically split internal magnetic shield for a display tube |
摘要 |
A method of manufacturing a magnetically split internal magnetic shield (19) which comprises two complementary parts (15) and (16). Two plate-shaped parts (15') and (16') of a ferromagnetic material are arranged next to each other at a distance d and welded together by means of a strip of a non-magnetic metal. Subsequently, an internal magnetic shield is formed from the twin plate by means of drawing, cutting and/or bending.
