Abstract

Process for determining disturbances of a moisture cross profile of a fibrous material web in a paper making machine, a paper making machine, and a measuring arrangement for measuring the disturbances, the process including guiding the fibrous material web by way of at least one water-permeable belt and collecting and draining off water released from the belt. The water is collected by several sections separated from one another. The process further includes measuring per time unit, the amount of water in each section, wherein the sections extend at right angles to a web running direction over only a partial section of the fibrous material web. The paper making machine includes at least one water-permeable belt, the belt being wrapped around a roll. The measuring arrangement includes a water collection device having the form of one of a trough or channel.
