Abstract
A device for processing a continuously running material web includes a machine frame with an ultrasonic generator unit with a sonotrode. A counter tool lies opposite the sonotrode, affixed on the machine frame. The material web is passed through the gap between the sonotrode and the counter tool; as a drive activated by a fluid pressure medium, to press the sonotrode that is movably mounted on the machine frame against the counter tool. A damper for damping vibrations of the sonotrode in the contact pressure direction is provided. This damper is connected at one end with the sonotrode, and at its other end to the machine frame so that vibrations excited by the web or by the counter tool are damped to such an extent that they are no longer noticeable in the processing effect.
