Abstract
A device for needling a prebonded web (1), comprises at least one needle board (3) reciprocatingly movable in a needling direction, and a web support (2) disposed opposite the needle board (3) between a feed roller (7) and a discharge roller (8). To avoid a stripper it is proposed that the needle board (3) be disposed directly opposite the web support (2), that the web support be provided with a continuous convex curvature in direction of web movement (6), and that the discharge rate of the discharge roller (8) exceed the feed rate of the feed roller (7).
