On-line sensing of paper machine wet-end properties: dry-line detector

Abstract

This paper is concerned with the task of sensing in web-forming process control loops. Conventional and newly proposed measurement techniques are discussed and a new type of measurement is suggested. The new measurement method adresses the problem of paper machine “wet-end” sensing and is based on a CCD camera system which can detect the dry-line. Both the… (More)
