<p>Two needling assemblies (8, 9) comprise each a needle board (12) and an alternating motion mechanism (14). A motor (18, 19) is provided for each needling assembly (8, 9). The needling assemblies (8, 9) are mechanically independent of each other. The motors (18, 19) are connected by an angular position servo-mechanism (21). The needling machine may be used to eliminate the mechanical resonances between needling assemblies and to diversify and facilitate the adjusting possibilities.</p> |
