Publication number: 20020166646Abstract: 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 creped 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 and compressive forces that act upon the base web.

Patent number: 6149768Abstract: A method of making a bonded and creped type absorbent paper web that has improved bulk to peel strength characteristics includes steps of (a) printing a low density pattern of a bonding material onto a first and a second side of a paper web; and (b) in no particular sequence with respect to step (a), printing a high density pattern of a bonding material onto the first side of the paper web. Steps (a) and (b) are performed so that the high density pattern of bonding material penetrates into the paper web by a distance that is about 166 to about 470 percent of the distance by which the low density pattern of bonding material penetrates into the web. This results in a web that has superior bulk and peel strength characteristics.

Patent number: 6132842Abstract: A cushioning product having plural layers of a sheet-like stock material folded upon themselves to form a pillow-like portion. The lateral edges of the outer layer of the stock material are overlapped and connected together to maintain the geometry of the pillow-like portion. The lateral edges of the outer layers are connected together (for example, they are mechanically interlocked) separate from the central portion of the outer layer. The overlapped edges of the outer layer may form a tab portion projecting from the pillow-like portion. Alternatively, the overlapped lateral edges of the outer layer may be generally coplanar with adjacent unoverlapped portions of the outer layer. Preferably, the stock material comprises layers of paper, more preferably biodegradable, recyclable and reusable paper, and even more preferably Kraft paper.Type: GrantFiled: March 16, 1998Date of Patent: October 17, 2000Assignee: Ranpak Corp.Inventors: James A.

Patent number: 6080466Abstract: The present invention overcomes drawbacks of prior composite sheets consisting of a spun-bonded nonwoven fabric and pulp fibers and provides an inexpensive composite sheet with excellent draping qualities, a nearly fabric-like touch and good usability. According to the present invention, a composite sheet made by entangling a web of thermoplastic filaments with pulp fibers under water stream is creped to increase the elongation in machine direction as high as in cross direction enough to obtain a usability equal to those of fabric wipers.Type: GrantFiled: November 12, 1997Date of Patent: June 27, 2000Assignee: Nippon Paper Industries, Co., Ltd.Inventors: Jiro Yoshimura, Akira Sakamoto, Hirotoshi Aikawa, Yoichi Yamazaki

Patent number: 6077390Abstract: High bulk tissue webs are processed sequentially through separate calendering and embossing units to optimize the balance between sheet caliper for winding tension and embossing element height for pattern definition, resulting in embossed, high-bulk tissue products with improved embossing pattern clarity. The multiple step converting process enables the use of male embossing elements having a height of about 0.04 inch or greater. The tissue webs have a Residual Waviness value of 12 micrometers or greater, which is attributable to average surface waviness values for the spot embossments being about 30 micrometers or greater.Type: GrantFiled: February 5, 1999Date of Patent: June 20, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Zeinab Salman, Richard Douglas Jennings

Patent number: 6077590Abstract: Rolled creped paper products, such as kitchen towels, can be provided with high roll bulk and a high degree of roll firmness by steaming the dry, creped paper sheet immediately prior to embossing the sheet between matched steel embossing rolls. The steaming preconditions the sheet such that the resulting sheet embossments maintain their shape and structural strength, thereby imparting greater bulk and firmness to the wound roll of product. In addition, the sheet experiences less cross-machine strength reduction as a consequence of the embossing.Type: GrantFiled: April 15, 1998Date of Patent: June 20, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Sammy Lee Archer, Eric John Draheim, Thomas Garrett Neal, Jr., Jerome Steven Veith, Mary Martha Zielinski

Patent number: 6077393Abstract: Certain alkylamides and alkylimides, such as hydroxy alkylamides, which ordinarily act as softening agents and substantially reduce the tensile strength of the tissue sheet in accordance with the strength/softness curve, have been found to have a significantly lesser effect on the strength of tissue sheets which have been noncompressively dewatered and dried. As a result, soft uncreped throughdried tissue sheets can be made to have a higher strength:softness ratio by incorporating these chemicals into the furnish.Type: GrantFiled: November 12, 1998Date of Patent: June 20, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Thomas Gerard Shannon, Nancy Sarsfield Clungeon, Sheng Hsin Hu

Patent number: 6030690Abstract: A process for high pressure embossing a single ply of paper and the paper produced thereby. The embossing process requires two rolls, a pattern roll 30 and an anvil roll 32. The rolls are loaded together at a pressure of at least 1000 psi at the nip. A single ply of paper is embossed in the nip. The embossments of the paper do not extend outwardly beyond the thickness of the paper to have any out-of-plane deformation. The embossments are typically glassined. The resulting paper has an aesthetically pleasing appearance, without undue loss of tensile strength from the embossing process.Type: GrantFiled: April 23, 1997Date of Patent: February 29, 2000Assignee: The Procter & Gamble CompanyInventors: Kevin Benson McNeil, Linda Rae Scherzinger, Thomas Anthony Hensler, Rebecca Ann Miller, Barbara Ann Ludwig
