Patent number: 8418645Abstract: The present invention relates to a doctor device for metering and/or leveling a liquid to pasty medium applied to a moving surface, the surface in the case of direct application being a paper, board or other fibrous web and in the case of indirect application being the surface of a transfer element which transfers the medium to the fibrous web. The doctor device includes a cylindrical metering rod and a pressure tube, with which the metering rod can be pressed against the moving surface for the purpose of metering and/or leveling the medium applied. Additionally, the doctor device is of modular design, having a top part and a bottom part, the top part being provided with a first holder for holding the pressure tube, and the bottom part being provided with a second holder for holding a clamping tube.Type: GrantFiled: December 18, 2006Date of Patent: April 16, 2013Assignee: Voith Patent GmbHInventors: Christoph Henninger, Horst Kaipf, Eckard Wozny, Martin Schaubmaier, Michael Heitzinger, Rüdiger Keinberger

Patent number: 7669550Abstract: A device for applying a medium in the form of a liquid or a paste to a moving substrate, the substrate being a surface of a web of paper, a paper board, fibrous material and/or a transfer element including an application chamber, a first element, a second element and at least one limiting element. The first element is associated with the application chamber on an output side of the application chamber in a direction of movement of the moving substrate. The second element is associated with an input side of the application chamber. The at least one limiting element is associated with a lateral end of the application chamber. The at least one limiting element adjusting a width of application of the medium on the moving substrate. The at least one limiting element having a flexible sealing plate that substantially seals a space between the moving substrate, the first element and the second element.Type: GrantFiled: June 7, 2005Date of Patent: March 2, 2010Assignee: Voith Patent GmbHInventors: Christoph Henninger, Horst Kaipf, Martin Schaubmaier, Michael Heitzinger, Ruediger Keinberger

Patent number: 7332033Abstract: A doctor bed is provided for holding a circularly cylindrical metering rod, including a housing of a homogenous material, which is designed with a cross section at right angles to the cylinder longitudinal axis of the metering rod and has a circularly cylindrical recess which surrounds the metering rod with a form fit over at least 180°. The doctor bed is arranged on a machine processing a moving material web, there being arranged on the housing, in the region of the recess, at least one groove running parallel to the cylinder longitudinal axis of the metering rod. A wiping strip is arranged detachably between the metering rod and the doctor bed.Type: GrantFiled: June 7, 2005Date of Patent: February 19, 2008Assignee: Voith Paper Patent GmbHInventors: Christoph Henninger, Horst Kaipf, Martin Schaubmaier, Michael Heitzinger, Ruediger Keinberger

Publication number: 20060243201Abstract: A doctor bed formed as a profiled strip having a continuous groove in the axial direction in order to hold a rotatable metering rod, which can be pressed against a moving surface and which meters and/or equalizes liquid to pasty medium applied to the moving surface. The moving surface, in the case of direct application of the medium, being one side of a paper, board or other fibrous web; and in the case of indirect application, being the surface of a transfer element which transfers the application medium to the fibrous web. Also disclosed is, for the production of the doctor bed, a material or a material combination selected including in a first variant of a homogeneous mixture of 70 to 99.8% polyethylene and 0.2 to 30% by weight of a wax of animal, vegetable, mineral or synthetic origin that is solid or liquid at room temperature.Type: ApplicationFiled: April 28, 2006Publication date: November 2, 2006Inventors: Christoph Henninger, Horst Kaipf, Bernard Fuchs, Martin Schaubmaier, Michael Heitzinger, Rudiger Keinberger
