Method and device for applying carbon to a cathode ray tube funnel

摘要

In applying an internal finishing carbon layer by flow-coating to an inner surface of a funnel of a cathode ray tube, when the internal finishing carbon poured onto the funnel's inner surface passes or after it has passed a region of the funnel at which a getter receptacle is provided, air is blown spotwise onto the internal finishing carbon. Thus, the amount of adhering internal finishing carbon in the region onto which air is blown can be reduced compared to the region onto which no air is blown.
