<p>An electrostatic spray charging head includes means (20) to support a spray-charging electrode (30) forward of a hydraulic spray nozzle (50) arranged to spray in a horizontal direction, in which the support means (20) includes upright surface features (22, 23) to trap incident spray liquid for dispersal with gravity assisted flow while the electrode (30) is of uprightly elongated form. Conveniently the electrode is embedded in an upright housing basally formed as a knife edge (34). The electrode and any housing may be open at the base.</p> |
