Abstract
Electrostatic painting apparatus comprises a support moveable at high speed along a slide. On this support is a pneumatically controlled paint sprayer producing an electrostatically charged jet of paint. A paint feed assembly comprising a pressure regulator and a discharge valve is juxatposed with the sprayer. Sprayer control devices are disposed on a chassis connected to the feed assembly by a harness. These control means comprise three gas pressure regulators supplying the sprayer and controlling the paint pressure regulator and a high DC voltage generator. The position of the chassis relative to the slide is determined such that the harness is as short as possible, so as to reduce to a minimum the command transmission time. This arrangement makes it possible to reduce the weight carried by the support. The units carried by the chassis are remotely controlled by a microprocessor-based unit over a remote control line.
