Patent number: 4849054Abstract: A bulky, embossed, fibrous web material having a basis weight in the range of 5 to 50 lbs./ream and geometric means tensile strength (TS) (kg/3" width), apparent bulk (AB) (cal. pts./lb. ream), and oil holding capacity (OH) (ml/gm fiber) substantially satisfying, in absolute values, the relationships (0.27 BW-1) TS>(0.17 BW-1), AB>[0.7-(TS.div.20)], and OH 0.063TS.sup.2 -1.13TS+8.6. The invention includes an apparatus and a method of manufacturing the product comprising wet pressing a fibrous web to about 30% to 50% solids, conveying the web to a transfer position proximate the three-dimensional surface of an embossing fabric moving at a speed less than that of the web at the transfer position, and applying a vacuum to the web through the embossing fabric to transfer and conform the web to the three-dimensional surface of the fabric, the vacuum magnitude being in the range of 1 to 20 inches Hg.Type: GrantFiled: January 14, 1988Date of Patent: July 18, 1989Assignee: James River-Norwalk, Inc.Inventor: Bernard G. Klowak

Patent number: 4834838Abstract: A sheet of fibrous web material having opposite smooth surfaces, an apparent bulk in the range of about 0.10 to about 0.20 caliper pts/lb ream and a machine direction stretch of at least 8%, wherein surface undulations on the opposite smooth surfaces of the sheet have an amplitude variance of less than 0.0002 inch. The invention includes an apparatus and a method of manufacturing the product comprising partially dewatering a wet fibrous web to about 30% to 50% solids, conveying the web to a compression nip defined by a smooth-surfaced roll and a smooth-surfaced fabric material, moving the fabric material at a speed of about 10% to 20% less than the surface speed of the smooth-surfaced roll, compressing the web in the nip with a compression force of less than 15 lbs/linear inch, with an average pressure of less than about 50 psi in the compression nip, and drying the web. The dried web has an apparent bulk less than 0.20 caliper pts/lb ream.Type: GrantFiled: February 20, 1987Date of Patent: May 30, 1989Assignee: James River CorporationInventor: Bernard G. Klowak

Patent number: 4610743Abstract: Two or more webs (11 and 12) of highly bulked substrate are passed into a nip formed between a gravure roller (14) and an impression roller (15). The impression roller has raised areas defining an interconnected network of lines such that the webs are compressed only under the raised areas; as a result, the binding liquid applied by the gravure roller (14) to the laminate of the two webs is absorbed substantially through the webs in the compressed areas. The gravure roller (14) may have a uniform surface, such that a light coating of binding liquid is applied to the surface of the uncompressed areas in the laminate, or the gravure roller may have a pattern of etched grooves or cells which matches and registers with the pattern of raised areas on the impression roller. In the latter embodiment, binding liquid will be absorbed into the laminate only in the compressed areas.Type: GrantFiled: September 22, 1982Date of Patent: September 9, 1986Assignee: James River-Norwalk, Inc.Inventors: Nilo I. Salmeen, deceased, Bernard G. Klowak

Patent number: 4482429Abstract: Paper webs are produced in a modified conventional felted wet press process in which the fiber furnish has a chemical debonding agent added thereto in high concentrations. The web (17) is formed on a conventional Fourdrinier wire (12), transferred to a moving felt (19) which presses the web against the surface of a drying cylinder (23) to reduce its water content, and is carried by the surface of the drying cylinder (23) to a creping blade (24). Liquid adhesive is applied to the surface of the creping cylinder (23) adhead of the contact with the web to provide substantial adherence of the web to the creping surface at the point of contact with the creping blade. The levels of addition of debonding agent to the pulp furnish and the amount of adhesive applied to the creping surface are selected such that the adhesion of the web to the surface at the creping blade is greater than the internal cohesion of the web.Type: GrantFiled: September 29, 1982Date of Patent: November 13, 1984Assignee: James River-Norwalk, Inc.Inventor: Bernard G.

Patent number: 4125659Abstract: A fibrous web is uniformly adhered to the surface of a smooth creping cylinder or other creping surface without causing substantial compression of the web. A raised pattern is pressed into the web toward the creping cylinder to cause the portions of the web that are pressed to adhere more strongly to the creping surface, while the portions of the web that are not pressed remain more lightly adhered to the creping surface. The web is creped from the creping surface with a creping blade, and the resulting product has a pattern creped appearance wherein the portions of the web that are pressed are finely creped while the portions of the web that were not so pressed are coarsely creped.Type: GrantFiled: June 1, 1976Date of Patent: November 14, 1978Assignee: American Can CompanyInventors: Bernard G. Klowak, Walter L. Pauls, Frederick J. Vermillon, Jr.
