Patent number: 10577744Abstract: A fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the equipment or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.Type: GrantFiled: February 6, 2017Date of Patent: March 3, 2020Assignee: AstenJohnson, Inc.Inventors: Samuel M. Baker, Rex Barrett, Bud J. Chase, Bruce W. Janda, Ian Gerald Lang, Dietmar Wirtz, Larry Anderson

Patent number: 9562319Abstract: A papermaking fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter in the papermaking system. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device in the dryer section to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters.

Patent number: 5200035Abstract: A method of foam forming of paper includes the steps of metering a controlled feed of fiber dispersed in an aqueous liquid into a dewatering device, wherein the consistency of the fiber dispersed in the aqueous liquid input to the dewatering device is between about 0.5 and about 7% by weight. A uniform continuous strand of semi-moist pulp is obtained wherein the consistency of the semi-moist pulp leaving the dewatering device is between about 8 and 30% by weight. A stream of a foamed aqueous admixture is obtained and introduced into a dispersing mixer having shearing action extending substantially throughout a zone substantially athwart the flow path of the uniform continuous strand and the foamed aqueous stream and forming a stream of dispersed fiber bearing aqueous foam. The dispersed fiber bearing aqueous stream is conducted to the inlet of a positive displacement pump.Type: GrantFiled: January 24, 1992Date of Patent: April 6, 1993Assignee: James River Corporation of VirginiaInventors: Dinesh M.

Patent number: 5178729Abstract: A foam-formed nonlaminated stratified paper tissue and method of making the same includes a first zone of foam-formed paper tissue formed from a furnish of hardwood fiber. A second zone of foam-formed paper tissue is formed from a furnish of softwood fiber. The second zone is formed unitary and entangled with the first zone to form a nonlaminated stratified paper tissue. A high softness integument is defined adjacent to an outer surface of the first zone and a substratum is defined adjacent to a surface of the second zone spaced away from the integument. The integument on the outer surface of the first zone includes an enriched region having a substantial purity of hardwood fiber and the substratum on the surface of the second zone includes an enriched region having a substantial purity of softwood fiber. The enriched region of substantially pure hardwood fiber provides an extremely soft and smooth surface detectable by human somatic sensibility.Type: GrantFiled: January 15, 1991Date of Patent: January 12, 1993Assignee: James River Corporation of VirginiaInventor: Bruce W.
