Method for adjusting the sprinkling pattern of a sprinkling apparatus and sprinkling apparatus

A sprinkling apparatus constructed as a square sprinkler has a nozzle arrangement with a straight row of nozzles, whereof each has a nozzle inlet connected by a nozzle duct to a nozzle outlet. At least in a portion between the nozzle inlet and nozzle outlet, the nozzles are constructed as rubber-like water guidance ducts, which are disconnectable by a force action transversely to the water flow direction. For the disconnection of individual nozzles clamping sliders are provided and are displaceable transversely to the water flow direction against the rubber-like nozzles and in the case of a displacement in each case disconnect or release again a nozzle. This permits a very variable adjustment of the sprinkling pattern.
