Ultrasonic welding device and ultrasonic welding method for controlling continuous ultrasonic welding processes

Ultrasonic processing device comprising the following features:

• an ultrasonic generator, a converter and at least one sonotrode with an oppositely arranged counter tool, which are spaced from each other by a gap, wherein the sonotrode or the counter tool is arranged rotatably and comprises an even circumferential surface, a controlling/regulating module, preferably a digital controlling/regulating module, which is integrated into a signal processing of the ultrasonic generator so that a plurality of generator data with respect to the ultrasonic generator are processible in the ultrasonic generator, especially an electric voltage U, an electric current I, an actual amplitude Aist and/or an actual generator power Pist, wherein
• a. a power actual value Pist is comparable with a power reference value Psoll of the ultrasonic generator by means of a gap regulator in the controlling/regulating module to specify a position reference value POSsoll of the sonotrode relative to the counter tool for adjustment of the power reference value Psoll of the ultrasonic generator, and/or wherein
• b. a power actual value Pist is comparable with a power reference value Psoll of the ultrasonic generator by means of an amplitude regulator in the controlling/regulating module to specify an amplitude reference value Asoll to the ultrasonic generator for adjustment of the power reference value Psoll of the ultrasonic generator.
