ABSTRACT:
Apparatus for sealing a mount including a wafer into a neck of a cathode-ray tube oriented along an axis comprises two tiers of burner tips. The first tier is disposed completely around the axis at a first distance therefrom and similarly aimed nonradially along directions tangent to a first circle. The second tier of burner tips is disposed completely around the axis below the first tier at a second distance from the axis and similarly aimed nonradially along directions tangent to a second circle. The first distance and the diameter of the first circle are greater, respectively, than the second distance and the diameter of the second circle.
