2195-24a ABSTRACT A mechanism which applies ink to selected portions of a running paper web has an imprinting roller and a counterroller. The web travels through the nip of these rollers, and the protuberances at the periphery of the imprinting roller receive ink from a trough by way of a withdrawing roller which dips into the supply of ink in the trough and a transfer roller which delivers a film of ink from the periphery of the withdrawing roller to the protuberances of the imprinting roller. At least the imprinting roller is hollow and confines a dynamic damping system whose natural oscillation frequency is attuned to that of the imprinting roller so that the system damps the oscillations of the imprinting roller when the mechanism is in use whereby the protuberances invariably transfer ink to selected portions of the running web. Additional damping system or systems can be installed in the counterroller, withdrawing roller and/or transfer roller. - 1 -
