Abstract

See full text

The present invention concerns a method of detecting the making or breaking of contact of a sonotrode (4) which is caused to vibrate with a frequency f and a vibration amplitude A0 with a counterpart element (5). To provide a method with which contact-making or breaking of a sonotrode with a counterpart element can be particularly quickly and inexpensively detected it is proposed according to the invention that the method has the following steps: a) recording a time configuration of the vibration amplitude A0 (1) during a first measurement time interval ΔT, and b) determining from the time configuration of the vibration amplitude A0 (1) whether making or breaking of contact occurred within the measurement time interval ΔT.
