Abstract
The invention relates to a method for supplying a paint application device with paint, whereby a determined amount of paint is transported between two scrapers through a scraper line, from a first scraper station which can be connected to a paint supply source, to a second scraper station which can be connected to the paint application device. Said scraper line is cleaned on the return path from the second scraper station to the first scraper station, by a cleaning product which is also transported between the two scrapers. In this way, the scraper line can be cleaned in a reliable manner, with a simple embodiment of the scraper, thus rendering the inventive method especially useful when a color change is carried out.
