Abstract: An installation for spraying a coating product on objects, such as motor vehicle bodies, that are moved by a conveyor (4) parallel to a conveying axis (X4) and having base (102) and mobile (104-108) portions. A multi-axis spraying robot (50) is dedicated to spraying a coating product. A multi-axis handling robot (60) is dedicated to maneuvering the mobile portion (104-106-108) of an object (100) to be coated relative to the base portion (102). Each robot is movable parallel to the conveying axis. Ventilation means provide a flow of ventilation air (F1) inside a booth (3), perpendicular to the conveying axis (X4). The spraying and handling robots (50, 60) are both slidably mounted along a same rail (8) parallel to the conveying axis (X4), and can pass each other. The rail is disposed upstream from the objects to be coated (100), in the direction of flow of the ventilation air (F1).
