Patent number: 6540879Abstract: A creping blade for creping a cellulosic web from a rotatable cylinder in a creping process includes first and second side faces. The first side face is at least substantially opposite to the second side file. The blade also includes an upper surface adjacent to the first and second side faces. A plurality of notches is provided along the upper surface. Each of the notches has a bottom portion and an open end defined by at least a portion of the upper surface. The notches are configured to increase the caliper of the cellulosic web when the creping blade crepes the cellulosic web from an outer surface of the rotatable cylinder. Creped paper and improved methods of manufacturing paper are also provided.Type: GrantFiled: March 19, 2002Date of Patent: April 1, 2003Assignee: Fort James CorporationInventors: Robert J. Marinack, Anthony O. Awofeso, Frank D. Harper

Patent number: 6534151Abstract: The present invention is generally directed to wiping products having great softness and strength. The wiping products are made from a web of material containing binder fibers alone or in combination with pulp fibers. Once the web is formed, the web is adhered to a creping surface and creped. According to the present invention, the web may be creped once or creped multiple times. Of particular advantage, the web can be adhered to a creping surface through the use of the binder fibers without the use of an adhesive.Type: GrantFiled: April 9, 2001Date of Patent: March 18, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventor: Joseph F. Merker

Patent number: 6517673Abstract: The present invention relates to a soft, thick, single-ply, printed, absorbent paper product having a Yankee side and an air side wherein the absorbent paper is printed on before or after embossing on the Yankee side, air side, or both sides, said absorbent paper exhibiting a serpentine configuration. This inventions also relates to a process for the manufacture of such absorbent paper product having a basis weight of at least about 12.5 lbs. per 3000 square foot ream and having low sidedness, said tissue exhibiting: a specific total tensile strength of between 40 and 200 grams per 3 inches per pound per 3000 square foot ream, a cross direction specific wet tensile strength of between 2.75 and 20.0 grams per 3 inches per pound per 3000 square foot ream, the ratio of MD tensile to CD tensile of between 1.25 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 3.2 grams per inch per percent strain per pound per 3000 square foot ream, a friction deviation of less than 0.Type: GrantFiled: May 10, 2000Date of Patent: February 11, 2003Assignee: Fort James CorporationInventors: Michael S.

Publication number: 20030000664Abstract: A process for increasing the tactile properties of a base web without adversely effecting the strength of the web is disclosed. In one embodiment, the process includes the steps of placing a base web 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. Base webs made according to the present invention have been found to have improved void-volume and fuzz-on-edge properties.Type: ApplicationFiled: June 28, 2002Publication date: January 2, 2003Inventors: Robert A. Drew, Patricia Riedl, Peter J. Allen, Brian Klaubert, Paul Arnold, Susan E. Smith, Michael A. Hermans, Phil S. Lin

Patent number: 6470945Abstract: A device for embossing and laminating a multiple-web web material, comprising: a first and second embossing cylinder (1, 3), provided with tips and arranged with parallel and adjacent axes so as to farm a nip (G) between them; a pair of pressure rollers, (5, 7), each of which cooperates with one of the embossing cylinders; an adhesive applicator (17) associated with the first embossing cylinder; and a laminating roll (13) arranged downstream of the nip (G) between the embossing cylinders (1, 3) and cooperating with the first embossing cylinder (1). Planes (P3, P5) contain axis (1A, 3A) of each embossing cylinder (1, 3) and the axis (5A, 7A) of the corresponding pressure roll (5, 7) are both inclined with respect to the plane. (P2) containing the axes (1A, 3A) of the embossing cylinders at an angle different from 0 and 90 degrees.Type: GrantFiled: August 8, 2000Date of Patent: October 29, 2002Assignee: Fabio Perini S.p.A.Inventor: Guglielmo Biagiotti
