Abstract
A device for processing a continuously running strip of material includes an ultrasonic generator unit with a sonotrode that is fixed opposite a counter roller. The material strip is processed in the gap. To adjust the gap height, the force in the gap is measured using a force measuring member, and used for regulation.
Claims5
An apparatus for processing a continuously running strip of material, comprising:
- a machine frame;
- an ultrasonic generator unit supported in the machine frame, the ultrasonic generator comprising a sonotrode;
- a counter tool that lies opposite the sonotrode and defining a gap therebetween, the counter tool being supported in the machine frame;
- means for passing a strip of material through the gap between the sonotrode and the counter tool;
- a drive for pressing the sonotrode against the counter tool, with rigid and positive-lock support on the machine frame;
- and
- a force measuring member located between the drive and the sonotrode that provides a signal, wherein the counter tool has a uniform embossing density and the signal serves to regulate the drive so as to provide a constant sonotrode force.
