Patent number: 7326301Abstract: A device for direct or indirect application of liquid or viscous coating medium by way of an application system onto a material web, especially a paper or cardboard web, including a weakening device for weakening the boundary layer of air that is carried along by the application surface. The weakening device is located prior to the applicator device viewed in direction of travel of the application surface. The weakening device includes a blowing device and a suction device. The blowing device is located prior to the applicator device when viewed in direction of travel of the application surface and produces an air flow in opposite direction to the direction of travel. The suction device is located prior to the blowing device when viewed in direction of travel of the application surface and sucks off at least a portion of the air flow that is produced by the blowing device, as well as at least a portion of the boundary layer of air that is carried along by the application surface.Type: GrantFiled: November 17, 2005Date of Patent: February 5, 2008Assignee: Voith Paper Patent GmbHInventors: Richard Bernert, Benjamin Méndez-Gallon, Manfred Ueberschär

Patent number: RE40857Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes. The base sheet of the coated paper is preferably formed square on a paper machine wet end and has on the order of 40-50% less filler than conventional sheet paper made for electrophotographic processes. After being formed and dried, the base sheet is provided with a top coat weight that is approximately 60% less than the typical coat weight used for conventional paper. The coating is formulated to have sufficient viscosity to stay more on the surface of the base sheet. The coated sheet is calendered to a medium gloss on the order of a 75° TAPPI gloss of about 45, both to preserve a degree of surface roughness to enhance runnability of the paper through an electrophotographic copier and to provide a pleasant and easily readable surface.Type: GrantFiled: March 22, 2004Date of Patent: July 21, 2009Assignee: NewPage Wisconsin System Inc.Inventors: Charles A.
