ABSTRACT:
A system is provided for the productive utilization of paint in a paint supply line, changing paint colors and cleaning paint lines by inserting and propelling a termination piston or slug having an outer diameter which forms a sliding fit within the supply line to wipe paint off the interior walls of the supply line. Preferably, the supply line is elastic and the termination piston squeegees the paint off the interior walls. A manifold is fitted with various valves to selectively supply pressurized air, solvent and two or more paint colors to the supply line. A process controller controls the timing of the valves of the manifold. The system can also be used to retrofit existing color changers in an economical yet environmentally sound fashion
