Patent number: 6482886Abstract: Fibrous product is externally sized by applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carboxylic acid comonomer. The preferred dispersions which have lower initial viscosities provide dispersion/starch dilute solutions with higher viscosities and improved external sizing effectiveness. Resulting fibrous products are adequately sized and exhibit excellent printability and strength properties.Type: GrantFiled: September 3, 1998Date of Patent: November 19, 2002Assignee: The Dow Chemical CompanyInventors: Malcolm F. Finlayson, Kenneth E. Springs, John J. Gathers, James L. Cooper, Walter L. Vaughn, Brian H. Schumann, Stephen M. Oliver

Patent number: 6436485Abstract: The invention relates to a method of applying a powder coating to a substrate (5), in particular a temperature-sensitive substrate such as wood, wood-fiber material, plastic, rubber, cloth, paper or cardboard, wherein a thermoreactive powder is applied as a base layer (6) to the uncoated surface of the substrate (5), and wherein by means of infrared radiation with at least some components in the near and/or short-wave infrared region the powder is warmed throughout to the cross-linking temperature and cured, or is warmed throughout to the gelling temperature and in a subsequent processing step cross-linking is completed and the coating is cured. To generate the infrared radiation in particular halogen bulbs (7) are used in combination with a reflector (8) to reflect the emitted radiation towards the substrate. The halogen bulbs (7) are operated in such a way that the emitted radiation has a flux-density maximum in the near infrared.Type: GrantFiled: September 15, 2000Date of Patent: August 20, 2002Assignee: Advanced PhotonicsInventor: Martin Sedlmeyr

Patent number: 6413591Abstract: A method for coating paper, wherein a coating composition containing coating particles is applied to the surface of a paper web containing lignocellulosic fibers to produce a coated paper web having coating particles bound to the paper web, and the coated web is dried. According to the method the surface area of the interface between the paper web and the coating particles is increased in order to enhance hydrogen bonding between the coating particles and the fibers of the web. The surface area can be increased by using a coating composition comprising fine fibrous material or by abrading the surface of the paper or paperboard web or both. The invention will improve the smoothness of the surface without addition of foreign polymer binding agents to the web.Type: GrantFiled: November 8, 1999Date of Patent: July 2, 2002Assignee: ISI-HEAD OyInventors: Bernhard Dettling, Heikki Ahonen

Publication number: 20020058105Abstract: A system for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-substrate contact area. An electrical force is created on the fluid from an electrical field (originating from electrical charges which are on the second side of the substrate) that is substantially at and downstream of the fluid wetting line. The electrical field can be generated by charges that have been transferred to the second side of the substrate from a remote charge generator.Type: ApplicationFiled: April 6, 2000Publication date: May 16, 2002Inventors: John W Louks, Nancy J W Hiebert, Luther E Erickson, Peter T Benson

Patent number: 6309704Abstract: A device for direct or indirect application of a liquid or viscous coating medium onto a moving material web, specifically a paper or cardboard web, includes an applicator unit which, in the direct application method, applies the coating medium in the form of a coating layer directly onto the material web at a point of application. In the indirect application method, the coating medium is first applied onto an applicator element, for example an applicator roll, which then transfers, at the point of application, the coating medium to the material web in the form of a coating layer. In addition, a drying device for drying of the coating layer is provided downstream from the point of application, viewed in the direction of flow of the material web. In the applicator unit, a device for moistening and/or warming the material web, coating medium or the coating layer is additionally provided before the drying device, viewed in the flow direction of the material web.Type: GrantFiled: January 12, 1999Date of Patent: October 30, 2001Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Harald Hess, Rüdiger Kurtz, Benjamin Mendéz-Gallon
