Abstract
The present invention relates to a method for intermittent ultrasonic processing of a length of material, wherein a length of material is moved through between a sonotrode and a counter-tool and the length of material is processed intermittently. In order to specify a method for intermittent ultrasonic processing of a length of material by which the disadvantages of the prior art can be avoided or at least reduced, according to the invention it is suggested that in a processing interval the sonotrode is stimulated by an ultrasonic oscillation with an oscillation amplitude A and in a movement interval the sonotrode is stimulated with an oscillation amplitude B, wherein B<A and during the processing interval and during the movement interval the length of material touches both the sonotrode and also the counter-tool.
