The invention pertains to a device and to a process for the application of liquid to a substrate, especially for the application of an adhesive to hygienic articles, in which the liquid is discharged through a liquid outlet (36) of a nozzle unit (12) and applied to a substrate, where the substrate is in relative motion with respect to the nozzle unit (12), and in which the liquid, after emerging from the liquid outlet (36) of the nozzle unit (12), is influenced by two gas streams, the two gas streams being produced by two slot nozzles (58, 60), each of which has an elongated gas outlet (62). The invention is characterized in that the elongated gas outlets (62) of the slot nozzles (58, 60), extend essentially in the direction of relative motion (64) between the substrate and the nozzle unit (12), and in that the gas streams emerging through the gas outlets (62) are adjusted in such a way that the liquid filament or ribbon emerging from the liquid outlet (36) is caused to execute an oscillating motion transverse to the direction of relative motion (64) between the substrate and the nozzle unit (12).
