Patent number: 8158047Abstract: A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas.Type: GrantFiled: August 10, 2010Date of Patent: April 17, 2012Assignee: Georgia-Pacific Consumer Products LPInventors: Galyn A. Schulz, Gary L. Worry, Kang Chang Yeh, Thomas N. Kershaw

Patent number: 7754049Abstract: The present invention is a method for maximizing water removal from an absorbent web in a press nip. The present invention uses a pressing unit having a blanket with a void volume and with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web. The improved pressure profile according to the present invention results in increased water removal and/or improved line speed. The void volume further increases water removal and/or improves line speed.Type: GrantFiled: October 18, 2007Date of Patent: July 13, 2010Assignee: Georgia-Pacific Consumer Products LPInventors: Steven L. Edwards, Robert J. Marinack, Jeffrey Charles McDowell, Gary L. Worry

Patent number: 7691228Abstract: 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: October 10, 2006Date of Patent: April 6, 2010Assignee: Georgia-Pacific Consumer Products LPInventors: 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
