摘要： The flat display screen for an image-forming tube consists of a front pane portion (2,2′) and a circumferential flange portion (3,3′). The flange portion has an outer surface with a circumferential solder edge (7,7′) on an end of the circumferential flange portion (3,3′) on an opposite side from the front pane portion (2,2′). The outer surface has a circumferential ring-shaped region (5,5′), designated a KC surface, which extends substantially parallel to a central axis (8,8′), which is perpendicular to a surface of the front pane portion (2,2′) passing through a center point on the front pane portion (2,2′). So that the flange portion height can be reduced without increasing the danger of implosion, the wall thickness of the circumferential flange portion (3,3′) of the outer surface between the solder edge (7,7) and the circumferential ring-shaped region (5,5′) is greater than a wall thickness of the circumferential flange portion in the circumferential ring-shaped region (5,5′). In a preferred embodiment the solder edge (7,7′) has a width that is less than the wall thickness of the flange portion (3,3′) between said solder edge (7,7′) and the circumferential ring-shaped region (5,5′). A pressing tool (10,10′) for making the display screen is also described.
摘要翻译：用于图像形成管的平面显示屏由前窗格部分（2,2'）和周向凸缘部分（3,3'）组成。凸缘部分具有在与前玻璃板部分（2,2'）相对的一侧的周向凸缘部分（3,3'）的端部上具有周向焊接边缘（7,7'）的外表面。外表面具有圆周环形区域（5,5'），其指定为基本上平行于中心轴线（8,8'）延伸的KC表面，该中心轴线垂直于前玻璃板部分（2）的表面，2'）穿过前玻璃板部分（2,2'）上的中心点。因此，能够减小凸缘部高度而不增加内爆的危险，焊接边缘（7,7）与外周面环状区域（7,7）之间的外周面的周向凸缘部（3,3'）的壁厚（5,5'）大于周向环形区域（5,5'）中的圆周凸缘部分的壁厚。在优选实施例中，焊料边缘（7,7'）的宽度小于所述焊接边缘（7,7'）和周向环形区域（7,7'）之间的凸缘部分（3,3'）的壁厚，（5,5'）。还描述了用于制造显示屏的按压工具（10,10'）。
