Abstract

The system has two reservoir containers and a device for electrostatic isolation of at least one container and a spray device from the delivery system so the container and spray device can be brought to a high voltage relative to the object. The isolating device has an insulating line section between the containers and a pad movable reciprocally in the line that removes electrically conducting coating material from its inner surface. The system has two reservoir containers (8,10) in series or in parallel and an isolation device (14,16) for electrostatic isolation of at least one container and a following spray device (12) from the delivery system so that the container and spray device can be brought to a high voltage relative to the object to be sprayed. The isolating device consists of an electrically insulating line section (18) between the containers that also forms the paint feed into the second container and a pad (22) movable reciprocally in the line that removes electrically conducting coating material from the inner surface of the line section as it passes through it.
