A web is passed over a surface ( ) 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 the curved surface. The temperature and moisture of the web are measured indirectly by measuring the temperature and moisture of the air cushion by several detectors ( ) which are in communication with openings ( ) formed in the curved surface in spaced relationship with one another in the cross direction of the web.
