摘要
The invention relates to the method and apparatus of maintaining spacing between tension mask strands (44) in a tension mask assembly (30) for a cathode ray tube (10). The tension mask assembly includes a mask frame (300) having a first pair of frame members (312A, 312B) disposed at opposite ends of the mask frame. The plurality of mask strands are disposed between the pair of frame members and affixed to the pair of frame members in a manner to produce tension in the mask strands. The tension mask assembly also includes barrier ridges (313A, 313B) which are between the frame members and are in contact with the plurality of mask strands in intermediate regions (402A, 402B).
