An apparatus is described which serves to needle a nonwoven web and comprises a slider crank mechanism, which is pivoted to a rocker and serves to actuate at least one needle board, which is secured to the rocker. The apparatus also comprises a web guide consisting of a web support, which is opposite to the needle board, and a stripper, which extends between the web support and the needle board. To permit an influence to be exerted on the result of the needling operation it is proposed that the mean inclination of the paths on which the needles of the needle board penetrate the nonwoven web relative to the direction of travel of the nonwoven web is adjustable. |
