  • 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. The contact pressure applied to a web in the processing zone is within the range of between about 0.01 MPa and about 200 MPa.

  • Patent number: 7429311
    Abstract: A method and assembly is disclosed for moistening a web of paper or paperboard, the assembly comprising a steam blow cavity open toward a moving web (1). The steam blow cavity houses spray nozzles (5, 6, 7) at least for injecting steam into the cavity so as to form a steam atmosphere therein. Additionally, the steam blow cavity houses spray nozzles (5, 6, 7) for spraying a mist of a heated liquid onto the web (1) within the thus formed steam atmosphere.

  • Publication number: 20060118256
    Abstract: A method of forming a coated printing paper product is provided. A printing paper product is first coated in a non-contact coating process. The printing paper product is then final calendered with a surface conditioning device. The coated printing paper product is formed for offset printing with a bulk of between about 1.15 m3/kg and about 1.3 m3/kg, and with the top side of the coated printing paper product having a PPS-s10 roughness of between about 0.7 ?m and about 1.5 ?m and a Hunter gloss of between about 30% and about 80%.
