A spray module 40 for manufacturing a cathode-ray tube (CRT) 10 comprises an enclosure 42 having sidewalls 44, a base 46 attached to the sidewalls 44, for closing one end thereof, and a panel support 48 having an opening, 50 therethrough. The panel support 48 is attached to an opposite end of the sidewalls 44. The spray module 40 has at least one electrostatic spray gun 36 therein for spraying charged screen structure material through the opening 50 in the panel support 48 and onto an interior surface of a faceplate panel 12 of the CRT 10. The spray module 40 includes a primary shield assembly 55 disposed within the enclosure 42 and extending through the opening 50 in the panel support 48. A secondary shield assembly 56 also is disposed within the enclosure 42 The primary and secondary shield assemblies 55 and 56, respectively, direct the charged screen structure material toward the interior surface of the panel 12, thereby increasing the transfer efficiency of the spray gun 36. A collecting tray 54 also is utilized to catch the spent spray which falls to the bottom of the spray module 40. The tray 54 is inclined toward a drain 100 that directs the spent material out of the spray module 40.
