Summary:An atomising bell or cup for use in a rotary atomising apparatus includes a general frusto-conical-shaped wall 56 having an outer surface and an inner flow surface 66 which terminates at an annular atomising lip 68. A plurality of radially outwardly extending fins or ribs 74 are formed on the inner flow surface 66 of the cup 16 upstream from the atomising lip 68 which are circumferentially spaced from one another to provide flow paths 85 therebetween for coating material flowing along the interior surface 66 of the cup such that the coating material is divided into a number of individual streams 84 before reaching the atomising lip 68. These streams 84 are emitted from between adjacent ribs 74 a short distance 79 upstream from the atomising lip 68 which allows centrifugal force to at least partially flatten the streams 84 forming ribbon-shaped streams 88, which, when flung outwardly from the atomising lip 68, for completely atomised coating particles which are substantially free of air bubbles.
