| Zusammenfassung: | 1 nA method and a device for tracking the position of the edge of a moving web, such as a fabric or a web of a paper machine, in which method a pressure-sensitive sensor element is disposed in/onto the surface of the roll guiding the web, which sensor element reacts to the pressure applied to it by the moving web by producing an electric signal, on the basis of which it is possible to determine the exact position of the edge of the web on the roll. The band-like sensor element comprises one single sensor strip or several sensor strips disposed successively in the band. |
