Patent number: 8082875Abstract: The present invention provides a doctor device for metering and/or equalizing a liquid-to-pasty medium applied to a running surface, wherein in the case of direct application the surface is a running paper web, paperboard web or other fibrous web and in the case of indirect application a transfer element which transfers the application medium to the fibrous web. The doctor device has a holder arranged on a support beam for accommodating a doctor element used for the metering and/or equalizing. The holder has a first fixed support face bar and a second moving support face bar, wherein to open and close the holder the second support face bar is displaceable respectively away from the first support face bar or toward it such that in the closed state of the holder the doctor element is fixed from the outside and in the open state of the holder it is released.Type: GrantFiled: February 20, 2007Date of Patent: December 27, 2011Assignee: Voith Patent GmbHInventors: Christoph Henninger, Benjamin Mèndez-Gallon, Ingo Gottwald, Franz Fischer

Patent number: 6589340Abstract: A coating machine serves to directly or indirectly apply a liquid or viscous coating medium onto a moving surface. A coater imbedded in a coater bed, defines in part the metering slot. A limiting surface at the moving surface inlet of the coater bed forms, together with the moving surface, an accumulator chamber, with the opening facing in the opposite direction with respect to the feed direction. The accumulator chamber gradually reduces its volume, and the coating medium, delivered to the accumulator chamber by the moving surface, accumulates in the area ahead of the metering slot. It further includes pneumatic pressure device to alter the relative position of the limiting surface with respect to the moving surface and thus alter the geometry of the accumulator chamber.Type: GrantFiled: November 24, 1999Date of Patent: July 8, 2003Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Richard Bernert, Benjamin Méndez-Gallon

Patent number: 6579368Abstract: An application apparatus is for applying a liquid or pasty medium to a moving base. The moving base is a surface of a material web in a case of direct application and a surface of a transfer element for transferring the medium to the material web in a case of indirect application, the material web being one of paper and cardboard. The application apparatus has an inlet side and an outlet side with respect to a direction of movement of the moving base. The application apparatus includes a carrying beam; an essentially rigid supporting unit provided on the carrying beam; a sealing doctor device positioned at the inlet side of the application apparatus, the sealing doctor device being fixedly attached to the supporting unit; and a metering doctor device positioned at the outlet side of the application apparatus, the metering doctor device being fixedly attached to the supporting unit. The sealing doctor device and the metering doctor device define an application chamber therebetween.Type: GrantFiled: July 21, 2000Date of Patent: June 17, 2003Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Bernhard Kohl, Stefan Reich, Benjamin Méndez-Gallon, Martin Kustermann, Manfred Ueberschär, Christioph Henninger, Rüdiger Kurtz, Martin Tietz
