Patent number: 7897015Abstract: Tissue products are described that have been topically treated with a chemical additive, such as a softener. The softener may be, for instance, a polysiloxane. The polysiloxane is topically applied to a tissue sheet, such as a single ply sheet, so as to form a Z-directional gradient in the sheet. Particular, most of the polysiloxane remains on the surface of the tissue product as opposed to migrating to the center of the sheet. In this manner, tissue sheets are formed with improved softness at lower levels of polysiloxane and without the need for applying any surfactants to the sheet. A system for applying chemical additives to tissue sheets is also described. The system includes a chemical additive applicator, such as a meltblown die that emits the chemical additive through a plurality of orifices. In one embodiment, the system includes a device for periodically cleaning the orifices during application of the chemical additive.Type: GrantFiled: June 30, 2008Date of Patent: March 1, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Kou-Chang Liu, Tom G. Shannon, Peter J. Allen, Geof Carlow, Mike Goulet, Paul Burden, Greg Aykens, Joe Capizzi, Thomas Hunt, Diane Linskens, Roger Wendler, John Wnek

Patent number: 6863205Abstract: An ultrasonic welder for splicing a plurality of workpieces has four anvils, each formed with a meeting surface and displaceable to form a workpiece nest, which has a rectangular shape of a predetermined width. The width of the workpiece nest is sufficient to receive only at least one vertical column of workpieces to be welded, so as to produce a vertical splice. The ultrasonic welder further has a controller controlling a starting position of tooling, which forms the predetermined width of the workpiece nest, and displacing at least one of tools, which form side faces of the nest in reciprocal and time controlled manner. The displaceable tool is brought back to its starting position corresponding to the predetermined width of the workpiece nest before a new bundle of workpieces is loaded therein.Type: GrantFiled: May 31, 2001Date of Patent: March 8, 2005Assignee: American Technology, Inc.Inventors: John Wnek, James A.
