The appts. for needle bonding a nonwoven fabric is structured so that, at least for part of the needles (3), and the gap (a) between the needle points (13) and the barbed hooks (12a) next to them is at least equal to the smallest gap between the stripper (7) and the underlay (6). The barbed hooks (12a) next to the needle points (13) move into the nonwoven (8) only when the needle points (13) have already penetrated the passage holes (10) in the underlay (6), to prevent undue bending forces on the needles (3). |
