Abstract: The invention discloses a spray pretreatment system and a method for pre-treating workpieces by spraying in a spraying tunnel, wherein the workpieces are fed into a treating station through an entry station. The inlet opening of the entry station is located below the level of the treating installations of the treating station. In this way, partial condensation of the vapors escaping from the treating station occurs in the entry station so that one can do without an extraction system in the area of the roof surface of the spraying tunnel. If desired, an extraction system with relatively low capacity may be provided in the region of the inlet opening.

Abstract: Devices and methods for coating wheel rims for the production of both standard rims and special rims, are provided. An example of a device for coating wheel rims includes a pre-treating station that is followed by a powder priming station followed by a basecoat application station and a final coating station, in particular an acrylate powder station, with the final coating station being coupled to both the power priming station and the pre-treating station by at least one conveyor, respectively. The device permits a proportion of special rims to be introduced in addition to standard rims without any impairment of the spindle-synchronous operation of the device.

Abstract: A cooling apparatus for cooling objects from a painting device is disclosed. The cooling apparatus comprises a housing enclosing a cooling zone, a transport device for transporting workpieces through the cooling apparatus along a transport direction from an entry region through the cooling zone and through an exit region. A heat exchanger is configured for cooling air from the cooling zone and to redirect cooled air into the cooling zone.
