Abstract

The method is for treatment of a spray pipe (3) to handle paint of a second colour/type after spraying a first type. A considerable volume of the first paint still in the pipe flows back into its storage container (5). The flow is generated by pref. a scavenging medium or compressed air. During the return flow, a signal-transmitting divider element (29) is positioned in the pipe between paint and medium. Residual paint in the pipe after the return flow of most of it, is pressed into a recycling pipe (11) and a recycling container (12). The pipe, and all components including the atomizer (2), are rinsed with a pulsating solvent and compressed air, and then with compressed air only.
