摘要： A method and arrangement for computing and regulating distribution of linear load in a multi-nip calender. A material web is passed through the nips in a set of rolls including a variable-crown upper roll, a variable-crown lower roll and intermediate rolls positioned between the upper and lower rolls. The rolls in the set of rolls are supported so that, when the nips are closed, the bending lines of the rolls are curved downwards. When computing and regulating the linear loads, one or more of the physical properties affecting the bending of each intermediate roll under load, such as bending rigidity, mass, shape, and material properties, are taken into account. The ratio of the linear loads applied to the intermediate rolls, the weight of the rolls per se, and/or the support forces applied to the rolls are regulated so that the set of rolls is in a state of equilibrium and a predetermined state of deflection.

By the way of these vibration detectors the calendar roll(s) (11 . . . 16) is/are identified from which the vibration derives. In the method , it is possible to observe the rotation of all of the rolls to be monitored and to measure vibration from any suitable point whatsoever, for example from the frame (100) of the machine, by employing at least one vibration detector (40), the time (Tr) of the cycle of the vibration signal obtained from said detector(s) being compared with the numbers of revolutions of the rolls to be monitored. In this way, the source of the disturbance is determined, and action is taken in order to eliminate the disturbance.

摘要： In a measurement method in the manufacture of paper or paperboard, different forces prevailing in a nip between a roll and a counter roll of an apparatus conveying a paper or paperboard web are measured. In the method there are several measurement points implemented with one or more film sensors (3) placed in the roll (1) in the transverse direction of the paper or paperboard web. The measurement information obtained from the measurement points by means of the sensor or sensors (3) is utilized to determine the pressure distribution of the nip. The film sensor (3) is a piezo- and pyroluminescent sensor from which the measurement information can be received optically at least in the initial stage, or a sensor comprising an electromechanical film (EMFi). The sensors (3) placed in the calender roll (1) can be utilized to measure the pressure distribution of the calender nip (N).

摘要： The invention relates to a method by means of which the machine-direction moisture of a web being coated 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 the coater section are controlled in an integrated manner in order to obtain a controlledly 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.
