Publication number: 20090255622Abstract: The disclosure relates an apparatus and method for assembling at least two webs of tissue paper with or without marking of the webs. The apparatus and method utilize a multi-marrying roller configuration, which allows for assembling of the at least two webs of tissue paper by passing between the marrying roller and the second marrying roller. The apparatus and method make it possible to produce a conventional embossed product, or a smooth product without marking, having combined plies. In addition, the apparatus and method make it possible to easily move from one production mode to the other.Type: ApplicationFiled: April 13, 2009Publication date: October 15, 2009Applicant: GEORGIA-PACIFIC FRANCEInventors: Joel HUNGLER, Yves-Michel MALECOT

Publication number: 20090193974Abstract: A membrane cartridge is manufactured by repeatedly folding and joining two strips of membrane to form a cross-pleated cartridge with a stack of openings or fluid passageways configured in an alternating cross-flow arrangement. The cartridge can be modified for other flow configurations including co-flow and counter-flow arrangements. Methods for manufacturing such cross-pleated membrane cartridges, as well as apparatus used in the manufacturing process are described. Cross-pleated membrane cartridges comprising water-permeable membranes can be used in a variety of applications, including in heat and water vapor exchangers. In particular they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams being directed into and out of buildings.Type: ApplicationFiled: January 14, 2009Publication date: August 6, 2009Inventors: Greg Montie, James Franklin Dean, Curtis Mullen, Robert Hill

Publication number: 20090190864Abstract: Methods for manufacturing airtight storage containers (e.g., bags or pouches) made from thermoplastic web material and having heat-sealed margins along a perimeter. To ensure that the storage containers are airtight, an unheated rib is pressed along each heat seal while the web material in the region of each heat seal is still in a softened and pliable state. As a result of the pressure applied, the rib deforms the contacted portion of the heat-sealed web material, leaving an indentation upon cooling of the web material that serves as an air leakage barrier. This air leakage barrier ensures that any air leakage pathway across the heat seal region is closed.Type: ApplicationFiled: January 28, 2009Publication date: July 30, 2009Applicant: ILLINOIS TOOL WORKS INC.Inventors: Martin Calvo, Linh Pham

Patent number: 7524404Abstract: An apparatus for producing an embossed product including a first embossing member having a plurality of discrete embossing elements disposed in a first non-random pattern having at least one first single pattern unit. The total area of the distal ends of the discrete embossing elements in the first single pattern unit is less than about 5.0 cm2. The apparatus also includes a second embossing member having a plurality of linear embossing elements disposed in a second non-random pattern having at least one second single pattern unit. The total area of the second distal ends in the second single pattern unit is less than about 10 cm2. The second non-random pattern is coordinated with the first non-random pattern such that when engaged with each other the first single pattern unit and the second single pattern unit make up an embossing pattern single pattern unit.Type: GrantFiled: June 8, 2005Date of Patent: April 28, 2009Assignee: The Procter & Gamble CompanyInventors: Donn Nathan Boatman, Kevin Benson McNeil, David Mark Rasch, Wayne Robert Fisher

Patent number: 7507311Abstract: Heat-sealed articles formed from polymer film portions heated-sealed together in selected areas forming a heat seal pattern, by passing the film portions together in a partial wrap about a heated sealing roller having a cylindrical outer surface that supports the film portions in a smooth cylindrical configuration about the roll. The cylindrical outer surface of the roller comprises a first surface portion defining a configuration corresponding to the heat seal pattern and formed of a first material having a first thermal conductivity, and a second surface portion formed of a second material having a second thermal conductivity lower than the first thermal conductivity such that only areas of the film portions in contact with the first surface portion are heat sealed together, the first and second surface portions being substantially flush with each other at the outer surface.Type: GrantFiled: November 3, 2004Date of Patent: March 24, 2009Assignee: Sealed Air Corporation (US)Inventor: Robert O'Dowd

Publication number: 20090071598Abstract: In the method of producing a resin sheet of the present invention, a first resin material and a second resin material are stacked and pressed by an emboss roller and a nip roller, thereby transferring irregularities on the surface of the emboss roller to the first resin material and closely contacting the first resin material to the second resin material, and the resulting laminate is wound onto a releasing roller to be released from the emboss roller. As the two resin materials are stacked in this way, unevenness on the backside produced immediately after molding is hardly generated and the desired cross-sectional shape can be obtained even in the case of a resin sheet with a wide thickness distribution in the width direction upon molding.Type: ApplicationFiled: March 15, 2006Publication date: March 19, 2009Applicant: Fujifilm CorporationInventors: Katsuhiko Takada, Takahiro Hayashi, Takekazu Yamamoto, Yasuyuki Hara

Publication number: 20090056859Abstract: An apparatus for providing a multi-ply embossed paper product having a first pressure roll; an embossing roll with a plurality of embossing protrusions, each embossing protrusion comprises a distal end; an adhesive application roll; a marrying roll; and a second pressure roll. The first pressure roll and the embossing roll are juxtaposed in an axially parallel relationship to form a first nip therebetween. The first nip has a first nip width. The first pressure roll and the embossing roll are adapted to receive a first paper web at the first nip. The adhesive application roll and the embossing roll are juxtaposed in an axially parallel relationship to form a gap therebetween. The adhesive application roll and the embossing roll are adapted to receive the first paper web, after the first paper web has traversed the first nip, at the gap. The marrying roll is juxtaposed in an axially parallel relationship with the embossing roll to form a third nip therebetween.Type: ApplicationFiled: September 5, 2007Publication date: March 5, 2009Inventors: David George Evans, JR., George Vincent Wegele
