What is described is an apparatus for needling a nonwoven, with at least one needle bar 1 for receiving a needle board 2, with a rocker 10 carrying the needle bar 1 and composed of at least two parallel arms 9 and with a slider-crank mechanism 6 engaging on the rocker 10 or on the needle bar 1. So that the stroke of the needle bar 1 can be adjusted, it is proposed that the slider-crank mechanism 6 be capable of being articulated on the needle bar 1 or on the rocker 10 at different distances from the axis of rotation 11 of the rocker 10. <IMAGE> |
