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