Abstract
An apparatus is described for needling a non-woven material with at least one needleboard ( ) which is drivable in a reciprocating manner by at least one eccentric drive in the needle-penetration direction, which needleboard is linked to the eccentric drive via push rods ( ) each displaceably held in a guide sleeve ( ), which eccentric drive consists of two parallel eccentric shafts ( ) which are drivable in opposite directions and are provided with connecting rods ( ), with the guide sleeves ( ) being swivelably held about an axle ( ) extending parallel to the eccentric shafts ( ). In order to provide simple constructional conditions it is proposed that the two eccentric shafts ( ) are provided with a different angular position (&phgr;) and that the connecting rods ( ) of the two eccentric shafts ( ) extend in an inclined manner with respect to each other.
