Abstract
The present invention concerns a sonotrode for a device for continuously processing material webs by means of ultrasound. To provide a sonotrode and an ultrasonic processing device having a sonotrode which is simple to produce and ensures reliable transverse sealing seam production, wherein the energy consumption of the sonotrode is low and the sonotrode also has a high level of rotational truth accuracy and adequate stiffness, it is proposed according to the invention that the sonotrode comprises a substantially roller-shaped core and at least two bars, wherein the bars extend in the direction of the core axis and each have a sealing surface facing away from the roller-shaped core.
