Abstract
L'invention concerne un système d'évaluation, au moyen d'ultrasons, des propriétés élastiques d'une bande continue de papier en mouvement. Un dispositif générateur d'ondes ultrasonores (1; 20), en produisant un signal ultrasonore du type bruit, donne naissance à l'onde ultrasonore dans la bande en un point d'excitation. Un dispositif de référence, récepteur d'ultrasons (Mic1, 7; 21, 7), est orienté de manière à recevoir, sans contact, l'onde ultrasonore provenant du point d'excitation. Au moins deux dispositifs de réception des ondes ultrasonores (Mic2A, 8, Mic2B, 9) reçoivent sans contact l'onde ultrasonore produite par le dispositif générateur susmentionné et renvoyée par la bande continue de papier. Des organes de traitement (8 à 10) compilent les sorties provenant des dispositifs de réception tandis que des moyens de calcul (13), traitent les sorties du dispositif de référence et ceux des moyens de traitement, et mesurent la temporisation existant entre ces sorties.
