An apparatus for needling a non-woven material which is drivable in a reciprocating fashion both in the needle-penetration direction (5) as well as the direction of passage (6) of the non-woven material comprises two connecting rods (10) of two oppositely drivable eccentric drives (8, 9) for the drive of a needle board support (3) in the needle-penetration direction (5), and at least one additional eccentric drive (12). The connecting rods (10) of the two oppositely drivable eccentric drives (8, 9) extend inclined in opposite directions with respect to the needle-penetration direction (5), and the additional eccentric drive (12) revolves synchronously with one of the two other eccentric drives (8, 9). The connecting rod (15) of the additional eccentric drive (12) is also linked to the support (3) and forms with the connecting rod (10) of the synchronously revolving eccentric drive (8) a parallelogram of links for guiding the support (3). The eccentric drives (8, 9) which are drivable in opposite directions, are provided with a phase shift ( d ), or are adjustable with respect to the mutual angular position. |
