ABSTRACT:
A method and apparatus are provided to clean a paint feed-line (1) of a painting system, line running from at least one paint tank (2, 9) to a paint deposition device (3) and feeding paint in this direction during the operational stages. During cleaning stages between operational stages, a cleaning substance is forced through the feed line (1). An inert gas, for instance nitrogen, is used as the gas for this purpose, and at the end of the cleaning stages the feed line (1) is filled with the inert gas. The gas remains in the feed line (1) until the next operational stage begins.
