An apparatus for needling a non-woven material is described, comprising at least one needleboard ( 1 ) which is drivable in a reciprocating manner in the needle-penetration direction ( 6 ) as well as in the direction of the passage ( 11 ) of the non-woven material, comprising an eccentric drive for the needleboard ( 1 ) which comprises two parallel eccentric shafts ( 2, 3 ) which are drivable in opposite directions and assume a different angular position (phi), and couplers ( 5 ) which connect the connecting rods ( 4 ) of the two eccentric shafts ( 2, 3 ) in an articulated manner and comprise a guide arm ( 8 ) which is rigidly connected with the same, and a lifting guide means ( 9 ) for the guide arms ( 8 ) which forms a swiveling axis ( 10 ) for the guide arms ( 8 ) which is parallel to the eccentric shafts ( 2, 3 ). In order to provide advantageous constructional conditions it is proposed that either the guide arms or the couplers carry the needleboard.
