ABSTRACT:
This disclosure depicts a novel method for dispensing a cement onto the seal land of a color CRT funnel. In particular, this method is intended for dispensing cement onto a funnel seal land which defines a convex curved plane, at least a curved segment of the seal land lying on a predetermined radius. The method comprises holding the funnel in a neck-down position, providing a substantially stationary cement dispensing nozzle and, in order to dispense cement on at least the segment of the curved seal land, swinging the funnel about the origin of the radius of the seal land segment such that the seal land segment passes under the cement dispensing nozzle at a substantially constant predetermined distance beneath the nozzle and in a substantially horizontal attitude. Apparatus is disclosed for implementing the described method.
