Patent number: 7462257Abstract: A process for producing tissue webs is disclosed. The process may include the step of partially dewatering a tissue web, subjecting the web to at least one deflection against a fabric, such as a coarse fabric, and then creping the web.

Patent number: 7419570Abstract: The present invention discloses a process and a method providing a high bulk tissue which is both strong and soft. Specifically, it has been discovered that certain low pressure printing technologies may be used to deliver a bonding material to the surface of a high bulk paper web such as an uncreped, through-dried web. The bonding material may be applied to the web either before, during or after the web is softened with a mechanical straining process which will decrease the web bulk by no more than 20% of the initial bulk in order to increase the web softness. The web may be softened by any of a variety of mechanical straining processes such as, for instance, microcreping, microstraining, rush transfer, or other low-compressive softening methods. The cured bonding material on the web may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency and the wet strength of the web.Type: GrantFiled: November 27, 2002Date of Patent: September 2, 2008Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Fung-Jou Chen, Jeffrey D.

The fabrics moves over vacuum boxes, and the web is heated with steam and passed between an upper pressure box and a lower vacuum box forming an air press which dewaters the web. A sheet transfer pickup vacuum box holds the sheet to the upper fabric as the lower fabric diverges from the upper fabric. A pressure roller transfers the web onto a Yankee dryer. The fabrics are cleaned on vertical runs before returning to the breast roll. A final forming fabric is arranged to operated at a lower speed than the penultimate forming fabric so that a rush transfer and creping like action takes place.Type: GrantFiled: March 7, 2005Date of Patent: July 10, 2007Assignees: Metso Paper, Inc., Mitsubishi Heavy Industries, Ltd.Inventors: Roger A.

Patent number: 7235156Abstract: A multi-layered paper product that has bridging regions for inhibiting nesting is provided. For example, the paper product can contain a first and second layer that define ridges and valleys. Bridging regions are formed into at least one of the outer surfaces of the layers. In particular, the bridging regions are positioned at an angle of between about 0° to about 180° relative to the ridges and also have a length sufficient to extend between the peaks of at least two of the ridges. The bridging regions can be formed in a variety of ways, such as with an embossing roll that contains embossing elements. Moreover, the bridging regions can also have a variety of shapes, sizes, orientations, and/or patterns.Type: GrantFiled: November 27, 2001Date of Patent: June 26, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventor: James L.

Patent number: 7182837Abstract: A process and method which ‘locks in’ three-dimensional texturing added to a paper web by virtue of an adhesive material which is printed onto the surface of the web is generally disclosed. The adhesive may be applied to the web either before, during, or after the web is molded to increase the surface texture. The adhesive may be applied at relatively low pressure so as to preserve surface texture without significant deformation of the web. The cured adhesive material inhibits the web from reassuming a two-dimensional state or may contribute additional texture by rising above the surface of the web. This process may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency, the wet strength, and the tactile properties of the web.Type: GrantFiled: November 27, 2002Date of Patent: February 27, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Fung-Jou Chen, Jeffrey D. Lindsay, Thomas F. Hunt, Maurizio Tirimacco, John J. Urlaub

Patent number: 7169458Abstract: Embossing regularly textured sheets with an appropriate regular, discrete embossing pattern to improve softness can result in a combined texture that creates an interference pattern that camouflages the original texture pattern and the embossing pattern. The resulting pattern is more appealing to the eye and is more random in appearance than the initial textured sheet or the embossing pattern individually. This result is particularly advantageous for paper towels.Type: GrantFiled: May 15, 2006Date of Patent: January 30, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Richard Louis Underhill, Paul Douglas Beuther, Robert Irving Gusky, Kevin Joseph Vogt

Patent number: 7160418Abstract: An improved process for making sheet from a fibrous furnish includes: depositing the furnish on a foraminous support; compactively dewatering the furnish to form a nascent web; drying the web on a heated cylinder; creping the web therefrom and throughdrying the web to a finished product. The microstructure of the web is controlled so as to facilitate throughdrying. The product exhibits a characteristic throughdrying coefficient of from 4 to 10 when the airflow through the sheet is characterized by a Reynolds Number of less than about 1. The novel products of the invention are characterized by wet springback ratio, hydraulic diameter and an internal bond strength parameter.Type: GrantFiled: March 23, 2004Date of Patent: January 9, 2007Assignee: Georgia-Pacific CorporationInventors: Steven L. Edwards, Greg A. Wendt, Robert J. Marinack, Michael J. Vander Wielen, Stephen J. McCullough, Jeffrey C. McDowell, Guy H. Super, Gary L. Worry

Patent number: 7156954Abstract: Soft throughdried tissues, which are sufficiently soft to serve as premium bathroom tissues, can be made without the use of a Yankee dryer. The typical Yankee functions of building machine direction and cross-machine direction stretch are replaced by a wet end rush transfer and the throughdrying fabric design, respectively. It is particularly advantageous to form the tissue with chemimechanically treated fibers in at least one layer. The resulting tissues have high bulk (about 6 cubic centimeters per gram or greater) and low stiffness.Type: GrantFiled: May 7, 2004Date of Patent: January 2, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Theodore Edwin Farrington, Jr., Julia Smith Bahlman, Mark Alan Burazin, Fung-jou Chen, Kristin Ann Goerg, Michael Alan Hermans, Robert John Makolin, Michael John Rekoske

Patent number: 7153389Abstract: A soft crepe paper machine comprises a wet section with a press section having a press defined by first and second press elements forming a press nip through which a press felt runs with a paper web. A suction roll is arranged in the loop of the press felt before the press nip at a distance from the second press element, and the felt with the web thereon runs around the suction roll with a large wrap angle. A drying cylinder forms the second press element. The first press element is either a solid press roll, a suction press roll, or a variable crown press roll.Type: GrantFiled: February 15, 2005Date of Patent: December 26, 2006Assignee: Metso Paper Karlstad AktiebolagInventor: Magnus Hultcrantz

Patent number: 7144478Abstract: The invention provides a method of preventing contamination of a dryer of a paper machine so that predetermined effects of contamination prevention over the long term can always be ensured while maintaining satisfactory drying efficiency. With the method of preventing contamination of the surface of the drum dryer used in a paper machine, a predetermined amount of a surface treatment agent P is continuously supplied to the surface of the drum dryer C1 in rotation, facing a paper strip W, while the paper strip is being fed by the paper machine in operation.Type: GrantFiled: September 14, 1999Date of Patent: December 5, 2006Assignee: Maintech Co., Ltd.Inventor: Kunio Sekiya
