METHOD AND APPARATUS FOR COATING A LOOP WITH VISCOUS MATERIAL ABSTRACT OF THE DISCLOSURE A method and apparatus for coating a seal edge of a funnel portion of a television cathode ray tube with frit slurry, which method includes the steps of arranging at least one pair of nozzle bodies containing frit slurry adjacent to the seal edge, predetermining initial points and terminal points on the seal edge corresponding to the number of pairs of nozzle bodies, moving the paired nozzle bodies from one of the initial points, in opposite direc- tions, along the seal edge while discharging the viscous material on the seal edge and having two of the nozzle bodies meeting each other at one of the terminal points. The whole seal edge is in this manner coated with a con- tinuous uniform layer of frit slurry.
