ABSTRACT:
The described apparatus for needling a nonwoven web comprises a slider-crank mechanism, which is connected to a rocker and serves to actuate at least one needle board, which is secured to the rocker, and web-guiding means comprising a web support, which is opposite to the needle board, and a stripper, which extends between the web support and the needle board. To provide a high needle density it is proposed that the needle board is arranged to extend at right angles to the direction of the mean inclination of the penetration paths of the needles of the needle board when the slider-crank mechanism is in a midstroke position in the middle of its stroke.
