Abstract

A long section of a glass tube 1 (Fig. 1) to be used, for example, as a filler tube for a gas display panel is held horizontally and rotated while seal paste 2 is dispensed from nozzle 3. The RPM of the tube 1 is adjusted so that paste 2 forms a bell-shaped deposit 4, which is immediately dried to remove the solvent vehicle from the paste.

Producing Presintered Seal Preforms on Tubes

A long section of a glass tube 1 (Fig. 1) to be used, for example, as a filler tube for a gas display panel is held horizontally and rotated while seal paste 2 is dispensed from nozzle 3. The RPM of the tube 1 is adjusted so that paste 2 forms a bell-shaped deposit 4, which is immediately dried to remove the solvent vehicle from the paste.

The deposits are then fired (Fig. 2) to remove the organic binder and sintered to a solid body. Sections 5 are cut in preform deposits 4 by a diamond wheel 6 (Fig. 3). Tube 1 is moved axially and cut in the middle of each section 5 and between each deposit 4 by diamond wheel 7 to produce individual tubes 8 (Fig.
4).
