Patent ID: 7299662

Claim:
An arrangement for ultrasound cleaning of several strandlike articles traveling next to each other, such as, e.g., wires, profiles and pipes, by means of a liquid excited by ultrasound in a borehole, which is only slightly larger, i.e., around 5-50% larger than the diameter of the article being cleaned, wherein the cleaning liquid is taken to the boreholes in such a way that it fills them completely, is hereby characterized in that, in an ultrasound sonotrode oscillating in air along its lengthwise axis (x axis) with a thickness of more than λ/4, boreholes are arranged transversely (y axis) to the main direction of oscillation (x axis) of the sonotrode to accommodate the article being cleaned, which are situated at the outer edge of the sonotrode and approximately in a row and at any desired interval from each other, so that the cleaning liquid in the boreholes is excited both by the oscillations along the main direction of oscillation (x axis) and by the thickness oscillations of the sonotrode material transversely (z axis) to the main direction of oscillation.
