Patent number: 6949166Abstract: “Products made from a process for increasing the tactile properties of a base web without adversely affecting the strength of the web is disclosed. In general, the process includes the steps of placing a base web in between a first moving conveyor and a second moving conveyor. The conveyors are then wrapped around a shear inducing roll which creates shear forces that act upon the base web. The shear forces disrupt the web increasing the softness and decreasing the stiffness of the web. The shear inducing roll typically has a relatively small diameter. In some applications, more than one shear inducing roll may be incorporated into the system.Type: GrantFiled: January 30, 2003Date of Patent: September 27, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Andrew P.

Patent number: 6939440Abstract: Paper products, such as wiping products, are disclosed that have a fabric-imprinted pattern in combination with a crepe pattern. In producing paper products according to the invention, a base web containing pulp fibers is formed. Once the base web is substantially dry, the web is creped to form a first pattern. The creped web is then placed between two moving conveyors and guided around one or more compression inducing elements. As the web is guided around the compression inducing element in between the two conveyors, shear forces and compressive forces are imparted to the web that form a fabric-imprinted pattern superimposed on the crepe pattern. In one embodiment, the fabric-imprinted pattern comprises high density troughs.Type: GrantFiled: December 18, 2002Date of Patent: September 6, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Robert A.

A chemical additive, such as softener or a humectant, is then chosen that includes a second moiety. When the chemical additive is applied to the article, the second moiety on the chemical additive forms a chemical linkage with the first moiety on the cellulose material. In this manner, the chemical additive becomes bonded to the cellulose material alleviating problems associated with retention. In one embodiment, the present invention is directed to the formation of tissue products, such as facial tissue, bath tissue and paper towels.Type: GrantFiled: December 23, 2002Date of Patent: July 12, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Thomas G.

Patent number: 6913673Abstract: The present invention is generally directed to a process for hot embossing a base sheet and/or to a process for perforating and bonding multiple plies of a paper product together. The process can be used in order to apply a decorative pattern to a paper product and/or to bond multiple ply products together. In one embodiment, the process of the present invention includes feeding a previously formed single ply or multi-ply base sheet through a heated embossing nip. As the base sheet passes through the heated embossing nip, sufficient heat and pressure is imparted to cause the fibers within the sheet to begin to melt or glassinate. Upon cooling, inter-fiber bonding occurs resulting in a well-defined embossment as well as bonding between plies of a multi-ply product.Type: GrantFiled: December 19, 2001Date of Patent: July 5, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James L.

The humectant can be selected from the group consisting of calcium chloride; lactic acid and its salts, high fructose corn syrup, glycerol, triacetin, sorbitol, maltitol, mannitol, propylene glycol, and any combination thereof. The plasticizer can be selected from the group consisting of urea, alkyloxylated glycols, dextrose, sucrose, ethylene carbonate, propylene carbonate, and any combination thereof.Type: GrantFiled: November 22, 2002Date of Patent: November 16, 2004Assignee: The Procter & Gamble CompanyInventors: Kenneth Douglas Vinson, Paul Joseph Coffaro

Patent number: 6808790Abstract: Paper sheets useful for tissues, paper towels, napkins, disposable absorbent products and the like can be made to exhibit a high degree of wet resiliency. This property is achieved by using a combination of high yield pulp fibers (such as bleached chemithermomechanical pulp fibers) and a wet strength agent in an uncreped throughdrying process. The resulting product, when wetted, can spring back after being crumpled in one's hand.Type: GrantFiled: May 23, 2002Date of Patent: October 26, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Fung-jou Chen, Mark Alan Burazin, Michael Alan Hermans, David Henry Hollenberg, Richard Joseph Kamps, Bernhardt Edward Kressner, Jeffrey Dean Lindsay

Publication number: 20040108243Abstract: A packaging material for cushioning an object packed in a container is disclosed herein. The packaging elements making up the packaging material may be made from sheets of paper, and be cup-shaped with a floor and thickened walls having irregular folds created by crushing the walls. Also disclosed herein is a method for manufacturing the packaging material that includes the steps of unrolling a paper roll, cutting the paper into paper sheets, pressing the cut paper sheets to form a cup, and crushing the walls of the cup towards the floor of the cup. A machine for implementing this method is also disclosed, and includes a mandrel for pressing the cut paper sheets, a sleeve for crushing the walls of the cup, and a stop block for holding the paper sheets.Type: ApplicationFiled: January 9, 2003Publication date: June 10, 2004Inventor: Philippe Jeannin

Patent number: 6743333Abstract: The invention relates to a paper machine clothing in the form of a fabric with a web pattern which recurs regularly over the surface and has indentations (20) that are formed by the thread overlays (21), the latter having been surface ground. Said thread overlays cover three consecutive warp or weft threads crosswise thereto. A paper machine clothing of this type can be used especially in “through air drying” techniques to produce an especially voluminous tissue paper.Type: GrantFiled: August 25, 2003Date of Patent: June 1, 2004Assignee: SCA Hygiene Products GbmHInventor: Hans-Jürgen Lamb

Publication number: 20040076798Abstract: An embossed paper (10), wherein the paper is a highly extensible Kraft paper (10′) and wherein discrete bosses (14) and/or depressions (12) consist of portions of said paper stretched at a dry content of 50-95% is disclosed. A two, three or multi-layer paperboard comprising at least one layer of the embossed and/or depressed paper (10) is also disclosed. Thus, the embossed paper may be used as such or instead of fluted paper in a corrugated board. The disclosed paperboard is easily creased and folded in both major directions, and in other direction as well. Method of producing the embossed paper (10) and a method or producing a two, three or multi-layer paperboard comprising at least one layer of the embossed and/or depressed paper (10) are also described.Type: ApplicationFiled: August 11, 2003Publication date: April 22, 2004Inventors: Nils-Ake Larsson, Tord Johansson
