<p>A rotary knife holder which is used in a transverse cutter for running paper webs or the like has a tubular carrier with an axial bore for a dynamic damping system serving to damp the natural frequency oscillations of the carrier. The damping system has a cylindrical mass whose end portions are surrounded by elastic annuli installed in a sleeve which is fixedly installed in the axial bore of the carrier. The natural frequency of the damping system is attuned to the natural frequency of the carrier. If the carrier is journalled at both ends, the damping system is installed midway between the ends of the carrier.</p> |
