摘要： AN APPARATUS INCLUDING A ROTATABLE SUPPORT FOR HOLDING A CATHODE-RAY TUBE COMPONENT, FOR EXAMPLE, A FUNNEL COMPRISING A SEALING SURFACE HAVING A CLOSED CONFIGURATION IN CLUDING RADIUSED CORNERS, AN INNER BORDER, AND AN OUTER BORDER, A MEANS FOR ROTATING THE SUPPORT, A SEALING-MATERIAL CONTAINER HAVING A BOTTOM OUTLET, A MEANS FOR TRACKING THE SEALING SURFACE WITH THE CONTAINER ALONG A FIRST PATH ON THE SIDES OF THE SEALING SURFACE, AND A MEANS FOR TRACKING THE SEALING SURFACE WITH THE CONTAINER ALONG A SECOND PATH DISPLACED TOWARDS THE OUTER BORDER ON THE CORNERS OF THE SEALING SURFACE. METHOD INCLUDES POSITIONING SEALING SURFACE OF THE CATHODE-RAY TUBE; FOR EXAMPLE, A FUNNELSEALING SURFACE IN A HORIZONTAL PLANE, MOVABLY POSITIONING A CONTAINER HAVING A BOTTOM OUTLET OVER THE SEALING SURFACE, ROTATING THE SEALING SURFACE ABOUT THE CENTER OF THE CLOSED CONFIGURATION, TRACKING SAID ROTATING SEALING SURFACE WITH THE OUTLET ALONG THE FIRST PATH, APPROACHING THE BEGINNING OF THE CORNERS OF THE SEALING SURFACE GRADUALLY MOVING THE OUTLET FROM THE FIRST PATH TO THE SECOND PATH, TRACKING THE ROTATING SEALING SURFACE WITH THE OUTLET ON EACH OF THE CORNERS AT THE SECOND PATH, APPROACHING THE ENDING OF EACH OF THE SEALING SURFACE CORNERS GRADUALLY MOVING SAID OUTLET FROM THE SECOND PATH TO THE FIRST PATH, AND DURING ROTATION DISPENSING A BEAD OF SEALING MATERIAL AT A UNIFORM RATE ON THE SEALING SURFACE.

摘要： The method includes positioning a mask-frame assembly in predetermined spaced relation with the inner surface of a faceplate of a cathode-ray tube by means of at least four retractable spacing units. The spacing units are each extended a predetermined fixed distance, and the mask-frame assembly is mounted in the panel. Then the spacing units are retracted to allow the mask to be self-supporting in the panel, and the spacing between the mask and the face-plate is measured at discrete positions without removing the retracted spacing units.
摘要翻译： 该方法包括通过至少四个可缩回的间隔单元将荫罩框架组件定位成与阴极射线管的面板的内表面预定间隔的关系。 间隔单元各自延伸预定的固定距离，并且掩模框架组件安装在面板中。 然后将间隔单元缩回以允许掩模在面板中自支撑，并且在离散位置处测量掩模和面板之间的间隔而不移除缩回的间隔单元。
