摘要: A method and apparatus for determining the profile of a coating layer of a paper or board web (2). The method comprises application of a coating slip to at least one surface of the web (2) at the coating head (1) of a coating machine, the measurement of the transverse temperature profile of the web (2) surface in at least a measurement point (7, 8) fitted after the coating head (1), and the determination of the profile of the web's (2) coating layer on the basis of the temperature profile measured in at least the measuring point (7, 8) fitted after the coating head (1), whereupon a change in the temperature of the web's (2) coating layer or in the difference of the temperature between the coating layer and the base web (2) is at least almost proportional to the change in the coat weight.
