Abstract
In order to decrease the resistance to the pulling of a nonwoven web in an apparatus for needling nonwoven webs, a perforated plate is proposed, in which at least those through holes which are formed in the perforated plate at least adjacent to its upstream end have downstream edge portions which are disposed in recesses, which are formed in that surface of the plate which faces the nonwoven web and which gradually taper to said planar surface of the plate in the downstream direction.
