<p>A coating material dispensing apparatus comprising a bell cup (10) and a motor (11) for rotating the bell cup about an axis of rotation of the bell c up. The motor is housed in a housing (13). A conduit (17) is provided for fe eding coating material to the interior of the bell cup as the bell cup is ro tated by the motor. The coating material flows to an edge (28) of the bell c up and is atomized therefrom in accordance with known principles. The housin g includes an annular slot (26) formed around the bell cup edge. Compressed air (29) is coupled to the annular slot to generate and direct a first air s tream (20) at an exterior of the bell cup. At least one additional opening ( 42) is formed in the housing radially outwardly from the annular slot. Compr essed air is also coupled to the at least one additional opening to generate and direct a second air stream (22) to combine with the first air stream to provide an air band.</p> |
