Abstract: A method for efficient utilization of hot air flows in a dryer system for goods to be dried is provided, in particular for a vehicle painting plant. Waste air from the dryer is heated in a thermal post-combustion plant and, as clean gas is conducted through circulating air recuperators, the circulating air extracted from the dryer is heated up and returned into the dryer. A device for efficient utilization of the hot air flows in a dryer system for goods to be dried is also provided, in particular for a vehicle painting system. The device includes a dryer, the waste air of which is heated in a thermal post-combustion plant. Clean gas is fed to circulating air recuperators and at least one fresh air recuperator. At least one additional heat source for the clean gas is also provided.

Abstract: In order to create a simple car body surface treatment device, a car body is introduced into and removed again from the treatment bath (11) simply by being rotated by a rotating device (2), at the same time as another car body is pushed onto and secured to said rotating device or conveyed past said device. The car body is fixed to a loading carriage (5) and is pushed by means of some driven rotary rollers (3a) onto the rotating device (2). By means of fastening devices (4a, 4b) the loading carriage (5) is detachably secured to the car body on the rotating device (2). By rotating through 180.degree. around an axis of rotation (7), the rotating device (2) dips together with the car body over its tail or front side into the treatment bath (11). While one car body is submerged, another loading carriage (5) together with the car body fastened thereon may be conveyed by the driven rotary rollers (3b) past the rotating device (2) for subsequent treatment, over the top surface of the rotating device (2).
