Apparatus and method for coating a moving paper web, in which method the web (2) to be coated is first guided to a coating station (7) correctly aligned and a first side of the web (2) is coated with a coat layer. Next, the web (2) is guided upwards from the coating station (7) and the first coat layer is dried using non-contact dryers (8, 9). From the dryers the web (2) is guided to the next coating station (14) correctly aligned and the second side of the web (2) is coated with a coat layer, the web (2) is guided upwards from the coating station (14) and the coat layer on the second side of the web (2) is dried using non-contact dryers (8, 9). When the web is directed from the coating station (7) via the dryers (8, 9), it (2) is guided non-contactingly by means of air jets such that the web (2) is first non-contactingly turned in the machine direction during drying and next, similarly during drying, towards the level of the coating stations (7, 14). |

| 222 | METHOD AND SYSTEM IN A PAPER MACHINE AND SOFTWARE PRODUCT | EP05808084.7 | 2005-11-11 | EP1836347A2 | 2007-09-26 | SUNDQVIST, Hans; NORRI, Petri |
| The invention comprises a method and a system in a paper machine, and also a software product, allowing one or more tools to be generated for indicating the state of the paper production process in terms of energy consumption to the operating staff of the paper machine. This allows continual monitoring of the state of the paper production process and/or its energy efficiency combined with efforts to develop the manners of running the paper machine and its dryer section in a more favourable direction. In one embodiment of the invention, the dry solids content DSC of the press section can be calculated by means of the evaporation amount of the dryer section, the production of finished paper and the final paper moisture as follows: DSC = m pap,d/( m pap,d + m H2O), in which m pap,d is the dry mass flow of the paper web to the dryer section and m H2O is the water mass flow to the dryer section. m H2O is obtained by summing up the mass flow of the water discharged from the dryer section and the evaporated water mass flow. | ||||||

| 227 | IMPROVED METHOD AND SYSTEM FOR COLLECTING AND HANDLING DUST IN A PAPERMACHINE ENVIRONMENT | EP00921886 | 2000-04-06 | EP1169110A4 | 2005-11-23 | COURTNEY KEVIN; KLYMENKO JERRY; WICKLUND PETER KEVIN; PONKA PHILIP |
| An improved process and system (22) for collecting and handling dust in a papermaking machine environment (20) wherein dust-laden air is drawn into and moves along an elongated collector (38 or 40) by way of a vacuum-generating source (42) connected to the collector involves the introduction of water into the collector so that the introduced water becomes entrained by the dust-laden air moving through the collector and wet-scrubs the dust-laden air upon entering the collector. With the dust being wet-scrubbed upon exiting the collector, the likelihood of ductwork fouling is substantially eliminated, and the risk of fire in the ductwork downstream of the collector is appreciably reduced. | ||||||

| A property of a paper web is measured using one or more reflectance measurement sensors emitting measuring beams onto the web and receiving the beams reflected from the web, from which the web property is deduced. The web is supported on a web support during the measurement, such as on a passive or active airfoil or fabric. One or more measurement sensor(s) can be integrated within an active airfoil, and can comprise a plurality of optical fibers having sensing ends arranged in the airfoil such that the sensing ends of the fibers face the moving paper web through one or more apertures in a web-supporting panel of the airfoil. Alternatively, a traversing sensor can be mounted within the airfoil. Other embodiments include a reflectance sensor mounted adjacent an airfoil or other web support such as a through-air drying fabric or a support belt for the web. | ||||||

| The invention concerns a method in a paper machine or equivalent, in which method water is removed out of the paper web (W) or equivalent by pressing, in which pressing stage the paper web or equivalent is pressed in at least one press nip (P). In the method, after pressing, the paper web (W) or equivalent is dried in at least one dryer group (Rp) based on impingement drying or equivalent. The paper web (W) is guided along a substantially linear path or by using a large curve radius. In the drying stage, after the impingement drying, the paper web or equivalent is dried in at least one dryer group (R1) in which a normal single-wire draw is applied. In the method, the paper web (W) is passed from the pressing stage to the drying stage as a closed draw. The paper web (W) is passed from the pressing stage (P) to the area (R1) with single-wire draw in the drying stage so that the paper web (W) is constantly supported against at least one support face (112, 313). Further, the invention concerns a device in a paper machine or equivalent, which paper machine comprises at least one press nip (P) and at least two dryer groups (Rp, R1). In the device, the paper web (W) or equivalent has a closed draw from the last press nip (P) to the first dryer group (Rp). The paper web (W) or equivalent has a substantially linear draw or a draw with a large curve radius through the first dryer group. The last press nip (P) in the press section and the first dryer group (Rp) in the dryer section are placed in the paper machine so that, on its run from the press section to the first goup (R1) that applies a normal single-wire draw in the dryer section, the paper web (W) or equivalent is constantly supported by at least one support face (112, 313). | ||||||

| The invention concerns a method of disinfecting paper or cardboard. During paper or cardboard manufacture, it is becoming increasingly important to destroy the microbiological-type germs remaining in particular in the lower layers of the fibrous material web of paper or cardboard to the greatest possible extent. To that end, according to the invention, during the manufacture of paper or cardboard on a papermaking machine, an electrical current of a value which is or can be predetermined is conducted through the paper or cardboard in a manner known per se from the drying of a paper or cardboard web, over a distance whose length is or can be predetermined and which is several times greater than the thickness of the paper or cardboard and extends at least substantially parallel to the longitudinal direction of the paper or cardboard web. | ||||||

| In the method for manufacturing surface-treated printing paper, a paper web is first dried down to a target moisture of the surface treatment, and it is wetted again to the target moisture before the surface treatment. The re-wetting to the target moisture is conducted on the web running to the surface treatment before a device effecting the surface treatment of the web, as seen in the travel direction of the web. Before re-wetting, the moisture profile of the web is adjusted in the drying section by wetting the web at a point which is located before the area of the heavy shrinkage (cd shrinkage area) in the travel direction of the web. | ||||||
