Abstract
In an apparatus for needling a web, which apparatus comprises a brushlike web support consisting of individual brush plates, it is desired to substantially eliminate an influence of the joints between the brush plates on the surface pattern of the needled nonwoven web. To that end the bristle tufts of those rows of tufts which extend adjacent to and along the joints between the brush plates are carried individually or in groups in alternation by the two brush plates which are disposed on opposite sides of the joint.
