Abstract
An apparatus which serves to needle a nonwoven web and comprises at least one needle beam for carrying at least one needle board, a rocker, which carries the needle beam and comprises at least two parallel arms, which are pivoted to a frame, and a slider-crank mechanism, which is coupled to the rocker or the needle beam. To permit an adjustment of the lift of the needle beam it is proposed that the slider-crank mechanism is adapted to be pivoted to the needle beam or the rocker at different distances from the pivotal axis of the rocker.
