Abstract
An ultrasonic processing method and an ultrasonic processing device may include 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. At this, a power actual value Pist is compared with a power reference value Psoll of the ultrasonic generator via a gap regulator in the controlling/regulating module to specify a position reference value POSsoll of the sonotrode relative to the roll for adjustment of the power reference value Psoll of the ultrasonic generator, and/or a power actual value Pist is compared with a power reference value Psoll of the ultrasonic generator via 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.
