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.

Abstract: A press for processing a web and a method of controlling a press. The press includes at least one nip having a first press roll and a second press roll. A first belt runs through the at least one nip. A second belt runs through the at least one nip. A sandwich stretch is formed by the first and second belts and is arranged after the at least one nip. A first mechanism is provided for driving the first belt. A second mechanism is provided for driving the second belt. The method includes driving the first belt at a first speed, and driving the second belt at a second speed, wherein the first speed is substantially the same as the second speed at least in a region of the sandwich stretch.

Abstract: Device for conditioning, cleaning, and/or keeping clean at least one of a rotating roll and a circulating belt of a paper machine. The device includes at least two doctors arranged behind one another in a roll and/or belt travel direction and spaced at a distance from one another. The at least two doctors are assigned to the at least one of the rotating roll and the circulating belt.
