Abstract: A method and apparatus for controlling the sequential coating of motor-vehicle bodies using a preprogrammed painter-robot is provided. As a result of wear, the signal/response delay times of valves and other control elements deviate from the information stored in the program. According to the subject invention, the actual signal/response delay time is measured and compared with the stored information stored in the program. In the event of unacceptable deviations in the actual verses stored signal/response delay times, the actuating times controlled by the program are changed in response thereto, and signals warning of excessive actual delay time are given.

Abstract: A device is provided for spraying an anti-corrosion agent into the hollow spaces of a vehicle body wherein one spraying nozzle, selected from a set of spraying nozzles which are each specific to a portion of the vehicle body, can be selectively coupled fluidically and mechanically by means of a quick change slip-on coupling to a spraying nozzle holder apparatus. To facilitate quick spraying nozzle changes by one hand operation and to make it possible to employ robots for the purpose of changing nozzles, all spraying nozzles are retained next to one another in a defined manner by retainers on a support so as to be fixed but detachable from said retainers. This arrangement permits the coupling component part of each nozzle to be easily accessible to the spraying nozzle holder apparatus.
