ABSTRACT:
In an apparatus for applying a viscous material, for example, a frit slurry, to a horizontally disposed seal edge surface of the funnel portion of a cathode ray tube through nozzles moved in a closed pattern above such surface, the frit slurry is supplied under pressure from a valved outlet of a container or other source through flexible hoses and then bellows to the nozzles, and the bellows are contracted and expanded in correspondence with the opening and closing, respectively, of the valved outlet.
