Abstract
Two needling assemblies have needle boards and alternating motion mechanisms. A motor is provided for each needling assembly. The needling assemblies are mechanically independent of each other. The motors are connected by an angular position servo-mechanism. The needling machine is used to eliminate the mechanical resonance between needling assemblies and to diversify and facilitate the adjusting possibilities.
