Patent number: 7862690Abstract: An apparatus and method for manufacturing a multi-layer web product. A long fiber stream is directed around a rotating carding cylinder. Two combing cylinders are disposed adjacent the carding cylinder to comb a first web of long fiber and a second web of long fiber, respectively, from the carding cylinder. A first conveyor receives the first web from the first combing cylinder and transports the first web toward a layering point. Similarly, a second conveyor receives the second web from the second combing cylinder and transports the second web toward the layering point. A short fiber deposition unit is disposed adjacent the second conveyor and deposits short fibers onto the second web. At the layering point, the first conveyor deposits the first web onto the second web, with the short fibers sandwiched therebetween, to form a layered web product.Type: GrantFiled: July 21, 2009Date of Patent: January 4, 2011Assignee: Georgia-Pacific Consumer Products LPInventors: Bradley G. Schmidt, Edward J. Yock

Publication number: 20080254081Abstract: A moist wipe having a web of fibers stabilized as with a suitable binder, and the stabilized, dry web having an anionic surface charge not greater than about 1.2 meq/Kg. A cationic functional agent in an aqueous imbuement is added to the web which is partially adsorbed by the web and a portion of the agent remaining free. Because the anionic surface charge on the substrate is relatively low, there remains in the free aqueous medium a sufficient quantity of the functional agent deliverable to the surface to achieve the desired efficacy. The resulting web will adsorb a limited amount of the cationic functional agent in the aqueous imbuement, and thereby an adequate amount of the agent remains in the solution free of the web for deliverance to the surface, thereby obviating high loadings of the imbuement and the active functional agent.Type: ApplicationFiled: June 16, 2008Publication date: October 16, 2008Applicant: GEORGIA-PACIFIC CONSUMER PRODUCTS LPInventors: Gary L. Schroeder, T. Philips Oriaran, Edward J. Yock, Bradley G. Schmidt, Michael E. Huss, Henry S. Ostrowski

Patent number: 7195810Abstract: An absorbent sheet made from an air-laid fiber web includes a functional emboss pattern of a continuous (wave-like) shape extending in the machine direction of the sheet. The emboss pattern defines a plurality of compressed regions operative to preferentially convey sorbed liquid away from the point of insult to prevent product failure. The sheet is particularly useful as absorbent core material within a multi-layer absorbent pad. In a further aspect of the invention, there is provided a method of making absorbent sheet utilizing an emboss roll provided with radially projecting circumferential sinuate bosses.Type: GrantFiled: April 21, 2000Date of Patent: March 27, 2007Assignee: Fort James CorporationInventors: Bradley G.
