Method for spraying surfaces, by moving spray nozzles mechanically through determined stroke length in one direction along surface and causing spray nozzles to move in further direction along surface at end of stroke length

摘要

The method utilizes spray nozzles mechanically moved through a determined stroke length in one direction along the surface and causing the spray nozzles to move in a further direction along the surface at least at the end of the stroke length, where the two directions enclose an angle, such that a spraying pattern is formed with parallel strips running in the first direction. The spray nozzles may moved reciprocally through the stroke length in the first direction. The spray nozzles may be active only during the forward stroke or the return stroke. Independent claims are included for a spraying device.
