METHOD FOR MEASURING THE TEMPERATURE AND MOISTURE OF A WEB

摘要

In the method, the web (W) is passed over a surface (11) which is at least partly curved in the running direction of the web, which extends across the web in the cross direction, and which is placed at a distance from the web, in which connection an air cushion is formed between the moving web and said curved surface. The temperature and moisture of the web are measured indirectly by measuring the temperature and moisture of said air cushion by means of several detectors (41) which are in communication with openings (40) formed in the curved surface in spaced relationship with one another in the cross direction of the web (W).
