    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.

    摘要: A nozzle (1) for use in coating a web-like material by means of high-pressure spraying techniques is manufactured by forming a piece having a tapered duct ending in a closed tip, with a transverse V-shaped groove (3) subsequently machined in the tip. The angle of the V-shaped groove (3) is in the range from 25 to 50°, such as 35 to 45°.

    摘要: A method for manufacturing a web of paper and paperboard, in which method a spray-coating technique is used for applying a web treatment substance to at least one surface of a moving web. The qualities of the web treatment substance are selected such that at least the droplet size and viscosity of the web treatment substance are controlled such as to make the thickness of the applied web treatment substance essentially equal in at least two randomly selected sample areas. According to the invention, the applied coating conforms with the surface contour of the base sheet. A paper manufactured using the method.

    摘要: An apparatus and method for preventing plugging of a narrow, slot-orifice-type jet nozzle 6 used in a paper and board coater in which the jet nozzle extends over the entire cross-machine width of the web being coated. The coater has an application chamber 11, a coating mix infeed channel 5 connected thereto and a clot orifice 6 as well as at least one inlet port 13 for feeding the coating mix into the application chamber 11. An easily cleanable strainer element 12 is placed close to the applicator apparatus to separate aggregates of the coating mix that otherwise could plug the slot orifice 6.
