Abstract
The needle loom for needling a nonwoven web comprises a needle beam arrangement, which comprises at least one needle beam, and a drive device for moving the needle beam arrangement back and forth in a punching direction. The drive device comprises a drive and two main shafts, on each of which a main conrod is eccentrically supported. The main conrods connect the main shafts to the needle beam arrangement in articulated fashion. The main shafts are driven rotationally in opposite directions. The drive device comprises an endless traveling transmission element, which couples the main shafts to each other. The transmission element also passes around first and second adjusting rollers. An adjusting device is provided for a translational adjustment of the position of the first and second adjusting rollers. This translational adjustment brings about a rotational adjustment of the phasing of the main shafts with respect to each other.
