  • Patent number: 7704351
    Abstract: A processing device and method applying the same for processing a coated or uncoated fibrous web is provided. The device comprises a belt configured to extend around a guiding element, at least one counter-element being disposed outside said belt to provide a contact area with the belt, such that the belt and the counter-element establish therebetween a web processing zone for passing a web to be processed therethrough. The processing zone length is defined by the disposition of the belt's guiding element and/or by the configuration of the counter-elements.

  • Publication number: 20050139157
    Abstract: A nozzle array for use in the coating of a mobile web-like material has a plurality of high-pressure nozzles (2.1, 2.2) in the transverse direction of the web. The nozzles (2.1, 2.2) have been classified by a variable acting on the flow so that the deviation of the variable within the array is smaller than a pre-set value. The yield of each nozzle being the same with optimal precision, an optimally even coating is achieved on the web.

  • Publication number: 20050123678
    Abstract: The surface of a continuous web, the fibrous portion of which consists of papermaking fibres, is coated with a coating powder. The web is allowed to move between electrodes, which are in different potentials. A coating powder of inorganic material and polymeric binder material is applied on the surface of the web by utilizing the difference in the electric potential. The coated surface of the web is then finished. The coating powder comprises 10.1-99.5 wt.-% of inorganic material. A dry surface treated sheet material is thus formed.
