Abstract
A sonotrode or ultrasonic welding apparatus for ultrasonically processing a material, including a sealing surface adapted to contact the material to be processed, a rear surface opposite to the sealing surface, and a circumferential lateral surface connecting the sealing surface to the rear surface, the lateral surface having two side surfaces arranged substantially parallel to each other and two end surfaces arranged substantially parallel to each other. In order to provide a sonotrode or ultrasonic welding apparatus for processing a material, which at least reduces damage to the material and at the same time does not impair the production speed, it is proposed that the sealing surface has a convexly curved inlet section which adjoins the lateral surface, and wherein the sealing surface has a coating at least in a section.
