Abstract
A device for needling a web (9), comprising at least one needle board (2) reciprocatingly movable in stitching direction, a stitch base (6) opposite the needle board (2) and a stripper (10) disposed between the stitch base (6) and the needle board (2), which stripper has through holes (11) for the needles (3) of the needle board (2). To create advantageous constructional conditions it is proposed that the stripper (10) should define a compressed-air space (13), which is disposed subsequent to the stripper (10) on the side opposite the stitch base (6) and can be connected with a compressed-air source (16).
