ABSTRACT:
Lacquer coatings are stripped from a large surface, e.g. aircraft and vehicle body surfaces, and the surface is simultaneously cleaned by a spraying device that carries at least three spraying units, each with at least one, preferably two, spray heads arranged in a row. Two outer spraying units flank one central spraying unit. The spraying device is secured to a free end of an outrigger arm on a mobile carriage, by a wrist mechanism, by a rod linkage, and by a mounting member (20a) tiltable by the rod linkage. The central spraying unit is directly secured to the tiltable mounting member while the two outer spraying units are secured by lazy tongues operable to track the contour of the large surface. Distance measuring sensors are arranged to measure the distance between the spray heads and the surface contour to provide respective distance signals to a central processing and control unit which controls the position of the spray heads in response to the distance signals and in response to optimal spacing values stored in a memory of the CPU to assure a desired spacing between the wall and all spray heads.
