The end caps are formed from initially flat, scored pieces of liner board which are folded in half upon themselves whereupon each leg member or half-section of the end cap is adhesively bonded to an outer surface portion of a respective one of the outer tubular liner board ply sections.Type: GrantFiled: July 1, 1999Date of Patent: August 13, 2002Assignee: Illinois Tool Works Inc.Inventors: Walter Gene Berrier, John Leslie Harrington, John Joe Howlett, Jr.

Patent number: 6429155Abstract: Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeability. The inventive inflatable fabrics are primarily for use in automotive restraint cushions that require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessarily low permeability levels. Thus, the inventive coated inflatable airbag comprises a film laminated on at least a portion of the target fabric surface wherein the film possesses a tensile strength of at least 2,000 and an elongation at break of at least 180%.Type: GrantFiled: January 22, 2001Date of Patent: August 6, 2002Assignee: Milliken & CompanyInventors: Shulong Li, John A.

Publication number: 20020068136Abstract: A pouch or other container for forming an envelope protectively packaging a product such as a flowable or solid food substance. The pouch is fabricated from a laminate sheeting whose plies have different properties that depend on package requirements, at least one ply in the laminate being an oriented, synthetic plastic film of high tensile strength. The plies are adhesively interlaminated at ambient temperature with a water-based adhesive whereby the orientation of the film is unaffected by the laminating process, in the course of which no environmentally objectionable fumes are discharged into the atmosphere. The laminate may also be made into a water-resistant envelope or package for mailing various materials.Type: ApplicationFiled: January 2, 2002Publication date: June 6, 2002Inventors: Arnold B. Finestone, Gilbert Bloch
