It is desired to provide an apparatus for needling a nonwoven web with a brushlike pierceable support and to provide surface patterns independently of a control of the depth of penetration of the needles. To that end the bristles of the covering of bristles of the pierceable support vary in accordance with a predetermined pattern as regards the bristle spacing and/or the extent to which the bristles protrude toward the nonwoven web.
