  • a third lock chamber is in turn above the second lock chamber approximately at the level of the first lock chamber and adjacent to this and is also connected to the second lock chamber via a large-area opening. It also contains an inert gas atmosphere and communicates with the inert gas atmosphere within the drying tunnel. The coated objects are guided through these lock chambers in the order listed.
