<p>The ultrasonic sealing device (1) has an ultrasonic generator (2), which is controlled in operating frequency or in output current and has two output terminals (3). A sonotrode (10) is provided that works with increasingly large oscillation amplitude to nominal oscillation amplitude. The rate of rise and fraction are selected in such a manner that the work surface of the sonotrode, remains in the oscillation condition with pressed work piece (16), comes in oscillation condition with pressed work piece respectively without overloading of ultrasonic generator.</p> |
