Travelling carrier for heating elements in a paint spray booth

The present invention concerns a method and an apparatus for accelerating the drying and/or curing of filler material, primer and top-coatings in connection with touch-up work on car bodies. According to the apparatus of the invention, grinding, filling and spraying are accomplished in one and the same booth, whereupon a carrier containing infra-red heat radiators and/or heating-elements and/or nozzles is traversed over the car, whereby controlled heat-energy is supplied to the surface accelerating drying and/or curing process of the surface treatment material. For supplying sufficient heat-energy to the front and rear parts of the car, special reflectors are located in front of and behind the car for reflecting heat-radiation from the carrier. The carrier is divided into sections with controlled, separate energy-supply and ventilation-air both when heat-transfer is accomplished and when the carrier is located in a parking recess, from which ventilation-air passes via specially designed slots out into the booth. The ventilation-air is conducted along the infra-red-radiators and/or heating-elements/air nozzles in a laminar air flow towards the car. The ventilation air is ventilated out from the sides and the floor of the booth. The travel of the carrier over the car body and the energization of the heating is programmed with respect to a given body configuration and with respect to the touch-up work being done in order to minimize wasteful use of energy to otherwise heat parts which do not require to be heated.
