In order to produce a needled nonwoven web having an improved surface quality, the needle board (1) of an apparatus for needling a nonwoven web should be provided with needles in a higher needle density. To that end the needles (2) of the needle board (1) are arranged in groups having a higher needle density and a perforated plate (5) of the stripper (4) and a perforated plate of the backing member (3) are provided in association with each group of needles with a common receiving hole (7). The needles (2) of each group are arranged in a longitudinal row generally extending in the direction of travel of the nonwoven web and are transversely offset from each other.
