Abstract: The invention relates to a method for manufacturing a fibrous web, such as web of paper, board, tissue or the like. The method comprises forming an aqueous fibre suspension comprising cellulosic fibres from one or more raw material flows, and applying at least one chemical and/or physical control measure to the aqueous fibre suspension or at least one of its raw material flows for control of microbial activity in the aqueous fibre suspension or the raw material flow before an inlet of an intermediate residence entity, such as storage tower or broke tower, which has a delay time of at least one hour, preferably at least two hours. In this manner a starting ORP value for the aqueous fibre suspension is obtained. The aqueous fibre suspension in the intermediate residence entity at least the minimum delay time, and a final ORP value is measured for the aqueous fibre suspension after an outlet of the said intermediate residence entity but before the formation of the fibrous web. An ORP difference value between the starting ORP and final ORP values is calculated, and if the ORP difference value exceeds a pre-determined threshold value, then adjusting the applied chemical and/or physical control measure(s) until the ORP difference value falls below the pre-determined threshold value. Finally, the aqueous fibre suspension is formed into a fibrous web and dried.

Abstract: The invention relates to a method for determining the amount of coating agent in coating agent layers (44) applied on a fibrous web (W) in respect of individual coating agent layers in multilayer curtain coating, in which method the fibrous web (W) is coated by curtain coating with two or more coating agent layers (44) by using a slide-fed curtain coater comprising a nozzle beam (40) with at least two feed chambers (12) and the nozzle slots (30) relating to them for feeding at least two coating agent layers on the runoff slide (35) formed by the nozzle beam (40). In the method, the amount of coating agent flow in each coating agent layer is measured from the feed line (22) of each coating agent layer before feeding the coating agent into the feeding chamber (12) of the coating agent layer. The amount of coating agent in each coating agent layer on the web is determined on the basis of the amount of flow measured by simultaneously taking into account at least the speed (V) of the fibrous web (W) and the width of the coating curtain applied. The invention also relates to an arrangement for implementing the method.

Abstract: The invention relates to a method by means of which the machine-direction moisture of a web being calendered or coated and calendered can be controlled in an optimal manner that takes into account moisture content changes along the entire path of the coating and drying process. Advantageously, all the dryers and the calender of the coater section are controlled in an integrated manner in order to obtain a controlled processed product which is optimized in regard to energy consumption and product quality. Each process section and unit contributing to the drying of the web is identified by means of a mathematical submodel describing the specific evaporation rate in the respective process section/unit and, by chaining these submodels, a composite model is compiled for the entire process, whereby the composite model makes it possible to manage the drying operation in the process so that the individual units are controlled as a portion of the overall process. In its simplest form, the composite model of the overall process comprises a submodel describing the behavior of the calender and at least one partial submodel describing the web processing unit preceding the calender.

Abstract: A sensor signal is generated from a plurality of sensors located on a sensing roll, wherein each signal is generated when each sensor enters a first nip between the sensing roll and a rotating component during each rotation of the sensing roll. A rotating applicator rod forms forming a second nip with the sensing roll such that each sensor enters the second nip during each rotation of the sensing roil. A periodically occurring starting reference is generated associated with each rotation of the applicator rod and the signal generated by each sensor is received so that a particular one of the sensors which generated the signal is determined and one of a plurality of tracking segments is identified. The signal is stored to associate the sensor signal with the identified one tracking segment.

Abstract: Das Verfahren dient zur Bildung von Calciumcarbonat in einer Faserstoffsuspension (1). Dabei wird Calciumhydroxid mit dem Faserstoff so in Verbindung gebracht, dass es verstärkt in das Faserinnere (Lumen) eindringt. Danach wird in einem Reaktor (5) gasförmiges Kohlendioxid (CO 2 ) zugegeben, wodurch Calciumcarbonat durch eine chemische Reaktion gebildet wird. Fasern, deren Lumen mit Füllstoff angereichert sind, lassen sich besser verarbeiten und bewirken besonders gute Eigenschaften bei daraus hergestelltem Papier.
