Abstract

<PICT:0773801/III/1> <PICT:0773801/III/2> A method of electrostatically spray coating a plurality of articles 30 comprises projecting outwardly from an atomizer 32 and electrostatically charging to a potential different to that of the articles 30 liquid coating particles in a spray of annular form, moving the articles 30 along a path 31a, 31b spaced from the atomizer 32, and maintaining in the spraying zone an electrostatic particle-repelling potential, e.g. by electrodes 33, 34 electrically connected to the atomizer 32, which directs particles towards the articles 30. The atomizer 32 and electrodes 33, 34 may be at high potential or at earth potential, the articles 30 being oppositely connected. The articles 30 may travel through 180 degrees about the atomizer 32, one electrode only being employed then. The atomizer comprises a disc 18 rotated by a motor 17 on a housing 15 to which two electrodes 20, 21 (corresponding to electrodes 33, 34) are connected. A voltage source 22 is connected to the housing 15 which is reciprocated vertically by a pneumatic device 23. Specification 741,313 is referred to.
