<p>The vessel or vessels (7, 7', 7") in contact with the solvent used for cleaning the conveyor (T) are designed and arranged in such a way that they are enclosed, and the portion of conveyor belt which is wetted with solvent is also isolated by suitable means from contact with the external environment containing the ventilation air of the painting chamber. In a preferred solution, where rotating scraping cylinders (1, 5) are used, the solvent vessel (7, 7', 7") is placed in such a way that it is enclosed by the two successive cleaning cylinders, by the portion of conveyor belt which runs between these cylinders, and by its lateral walls which are as close as possible to the said cylinders and to the said portion of the conveyor belt. At the end of each painting cycle, clean solvent is made to flow into the solvent vessel and the cleaning cylinders and the conveyor belt of the painting machine are temporarily kept active so that they clean themselves. <IMAGE></p> |
