New Method for On-Line Measurements of Elastic Properties of a Running Paper Web-Background and Mill Experiences, 1997 Process & Product Quality Conference Proceedings

On-line measurements of strength and elastic properties of paper is of very high importance for enabling optimization of the papermaking process. A new method for measuring paper’s elastic properties on-line the paper machine by using ultrasound has been developed. The unique feature of the method is a “semi-contacting” sensor which generates the ultrasonic signal with a minimum of impact on the paper’s surface, and picks up the signal without any contact with the paper. On-line ultrasonic sensors are installed at two different paper machines since more than a year. These trials have generated a lot of valuable information about the application of the method. This paper describes the background of the method, as well as some experiences and applications from the two mill installations.
