A nonwoven laying apparatus (3) and a nonwoven laying method are based on a laying device (7) that folds a delivered fiber web (4) and forms a multilayer nonwoven fabric (14) on the discharge path (15) of a discharging conveyor (13) that runs transversely or at an angle to the feeding direction (26). The travel profile of the discharge path (15) is set in such a way as to vary in the discharge direction in the vertically projected zone below the web outlet (12) of the laying device.
