Abstract
The invention relates to a sonotrode for an ultrasonic welding device having an ultrasound generator that supplies high-frequency electrical energy to a converter that converts this energy into mechanical vibrations and conveys the latter, optionally via a booster, to a sonotrode (2), the said sonotrode (2) being formed with a contact surface (3). In order to avoid troublesome sink marks it is proposed that pegs (1) be arranged on the contact surface (3).
