The invention involves an injector which propels a curtain of water through perforations in a rotating cylinder. The curtain of water hits a non-woven fiber sheet at an angle, and the splashback is collected in a suction chamber. The width of the curtain of water is adjustable, and self-cleaning of the injector can take place while the machine is in operation. The invention is used for the production of perforations or embossed designs on non-woven fabric whether the fiber sheet is produced by the dry method or the wet method.
