Abstract

Nozzles (23) producing liquid jets are distributed over several separate zones which are distanced from one another in the transport direction (24) of the workpiece (11). Alternatively, the nozzles are distributed over a single zone, and the workpiece is movable past them several times, with only a part of the nozzles being activated during each pass.
