Patent number: 7802377Abstract: The invention relates to a drying cylinder which is used to dry a paper, cardboard, tissue or other web of fibrous material in a machine for the production and/or for the transformation thereof. The drying cylinder includes a support body and an external cover layer which is heated by a hot fluid. The thermal flow passing through the external cover layer is increased such that at least one cavity is provided between the support body and the external cover layer through which the fluid flows. The external cover layer is predominately so thin that the ratio formed by the thermal conductivity of the material and the thickness of the external cover layer is greater than a threshold value of 3.2 kW/m2K for steel, 30 kW/m2K for aluminum, 18 kW/m2K for bronze alloys, 3.4 kW/m2K for copper and 6.1 kW/m2K for magnesium.Type: GrantFiled: June 28, 2007Date of Patent: September 28, 2010Assignee: Voith Patent GmbHInventors: Rainer Kloibhofer, Christoph Haase, Thomas Gruber-Nadlinger, Herbert Boden, Erich Rollenitz, Manfred Gloser

Patent number: 7510086Abstract: This invention relates to an arrangement for sealing off a fluid-filled, stationary pressurized compartment from an endlessly circulating, impermeable belt of a machine for producing and/or refining a paper, paperboard, tissue or other fibrous web with the help of at least one seal of the pressurized compartment, whose contact pressure toward the belt is variable, wherein the belt is pressed by the pressurized compartment against a co-driven support element and the fibrous web runs alone or jointly with one or more function belts between the belt and the support element. The sealing is improved in this case, while producing as little leakage and wear as possible, in that the contact pressure of the seal is controlled as a factor of the drive power and/or the drive torque channeled into the belt and/or as a factor of the leakage of fluid through the gap between the seal and the belt and/or as a factor of the pressure of the fluid in the pressurized compartment.Type: GrantFiled: December 1, 2006Date of Patent: March 31, 2009Inventors: Joachim Henssler, Christoph Haase, Herbert Boden, Helena Johansson

Publication number: 20080276483Abstract: The invention relates to a drying roll for drying a fibrous material web, in particular a paper, cardboard or tissue web in a machine for producing and/or finishing said fibrous material web. The roll can be heated on the interior by a gaseous heat transfer medium and the internal surface of its jacket is provided with elevated sections that extend at least radially inwards, the height of said elevations being greater than the average radial thickness of the condensate layer that forms on the internal surface of the cylinder jacket during operation. The roll is equipped with elements that drain condensate from the condensate chamber that incorporates the areas lying between the elevations. The condensate chamber or at least one condensate sub-section is in hydraulic contact with at least one front-end region of the cylinder.Type: ApplicationFiled: October 31, 2007Publication date: November 13, 2008Inventors: Herbert Boden, Rainer Kloibhofer, Thomas Gruber-Nadlinger, Gunter Seitlhuber, Robert Bunzl
