Apparatus for treating a textile web with ultrasound

Abstract

A device for treating a continuously advancing material web with ultrasound includes an ultrasound generator and a sonotrode, rigidly connected with the former in a manner so as to transmit ultrasound. The sonotrode has a face which lies opposite a counter-tool. The material web is passed through the gap. The module composed of the ultrasound generator and the sonotrode is connected with the machine frame via a piezoelectric actuator, by means of which small displacements of the face of the sonotrode relative to the circumference surface of the counter-roller can be balanced out.
