Abstract

PURPOSE: To prevent the remaining of a slurry film on the most fringe locus of a skirt portion of a glass panel, by applying phosphor slurry on an inner surface of the glass panel after beforehand moistening the skirt portion once by slurry.
CONSTITUTION: When a glass panel 23 of a color picture tube is held by means of a carrier 24 and turned, and phosphor slurry 25 is injected to the central portion and applied, an injection head 71 functioning by means of air cylinders 72, 74 is mounted, a cam 76 is contacted with a rotating skirt portion 27 by the working and the slurry 25 is injected for a short time from a nozzle 77 and the slurry 25 is injected from the central portion of the panel and applied. Thus, the quality and reliability of the picture tube is improved while factory expenses can be decreased because a slurry film remaining on the most fringe locus of the skirt portion 27 becomes extremely thick, is not removed in a trimming process and is not left as it is.
