Abstract (en)
[origin: EP1384804A1] The needling machine, for needle bonding a nonwoven, has a needle board (7) with an array of parallel needles, moved up and down by a drive. The needles are aligned with openings in an upper plate (2), to pass through the plate and the layer of fibers (3) to be bonded and through a lower plate (1). Compressed air is blown through jets (16,17) as a stream (F) which is passed laterally over the surface of at least one of the plates, while not in contact with the fiber material, during at least part of the time while the needles are bonding the fibers.
