Patent number: 7691224Abstract: A thermal polymer-bonding method includes initially placing into contact certain polymer-based first and second solid media at a first junction. A first superficial portion of the first solid medium is liquefying through the application of thermal energy to the first junction.

Molten nonelastomeric thermoplastic material of the discrete polymeric region is forced against the substrate by a transfer roll. If the substrate is porous, fibrous, etc., a portion of the nonelastomeric thermoplastic composition may infiltrate the substrate and/or encapsulate fibers of the substrate.Type: GrantFiled: November 5, 2001Date of Patent: September 13, 2005Assignee: 3M Innovative Properties CompanyInventors: Randall L. Alberg, Bradley W. Eaton, Leigh E. Wood

Patent number: 6936125Abstract: A method of securing an elastic strand to a flat substrate or sheet of material moving the elastic strand and the sheet in a converging manner from a first position in which the elastic strand is spaced from the sheet to a second position in which the elastic strand contacts one surface of the sheet. A filament of adhesive is dispensed onto the strand in a pattern configured with adhesive masses coupled by thinner filament sections. The adhesive masses are contacted with the strand when the strand is in the first position. The strand is bonded to the substrate with at least the adhesive masses.Type: GrantFiled: October 29, 2002Date of Patent: August 30, 2005Assignee: Nordson CorporationInventor: Michael Harris

Patent number: 6899775Abstract: This invention relates to the printing of a substrate having a pre-printed “print pattern” with a “design layer” of ink where there is differential adhesion within and without the print pattern. The print pattern is receptive to an ink, and the design layer ink forms a durable image material with good bond to the print pattern, but the ink does not form a durable image material on the portions of the substrate outside the print pattern. The design layer ink is a UV-curable ink, and the print pattern may have a higher surface energy than the portions of the substrate outside the print pattern.Type: GrantFiled: January 23, 2003Date of Patent: May 31, 2005Assignee: Contra Vision Ltd.Inventors: George Roland Hill, Chris David Parry

Patent number: 6881471Abstract: A high speed embossing and adhesive printing process using a first and second embossing rolls having complementary embossing pattern disposed thereon. A web of sheet material is placed in contact with an adhesive applied to the first embossing roll. The adhesive forms an adhesive pattern on the web of sheet material in register with the first embossing pattern of the first embossing roll. The web of sheet material is then passed between the first and second embossing rolls which emboss the web with the complementary embossing pattern.Type: GrantFiled: October 25, 2001Date of Patent: April 19, 2005Assignee: The Procter & Gamble CompanyInventors: John William Toussant, Kenneth Stephen McGuire, Stephan Gary Bush, Donald A. Salsman, Jeffrey Moss Vaughn, Kevin Benson McNeil

Patent number: 6872792Abstract: An adhesive or coating composition prepared by mixing together at least one metathesizable highly-reactive cycloolefin (e.g., a norbornadiene) and a metathesis catalyst. The use of highly-reactive cycloolefins can provide exceptional adherence to a low-surface-tension substrate. Another embodiment is a two-part adhesive or coating system wherein the first part includes at least one first metathesizable material, and the second part includes at least one liquid metathesis oligomer or polymer and a metathesis catalyst.Type: GrantFiled: June 25, 2001Date of Patent: March 29, 2005Assignee: Lord CorporationInventors: Jonathan L. Kendall, Kenneth C. Caster

Patent number: 6866928Abstract: The present invention provides a multi-layer tape, comprising: a first adhesive layer comprising a pressure sensitive adhesive; a core layer having an outer surface, the first adhesive layer adhered to at least a portion of the outer surface; and fibrous reinforcing material dispersed within the core layer, the fibrous reinforcing material imparting stretch release properties to the tape. The tape may comprise a second adhesive layer wherein the outer surface comprises a first major surface and a second major surface, the first adhesive layer being adhered to the first major surface, and the second adhesive layer being adhered to the second major surface. A fire retardant may be disposed in any of the first adhesive layer, the second adhesive layer, and the core layer. The tape may be cleanly removable.Type: GrantFiled: April 8, 2002Date of Patent: March 15, 2005Assignee: 3M Innovative Properties CompanyInventors: Timothy N. Narum, James J. Kobe, Rodger J.

Patent number: 6818248Abstract: A flame retardant adhesive tissue paper for fabricating moldable structures, particularly suitable for forming laminates for the interior of automobiles is provided. The flame retardant adhesive tissue is prepared by screen printing an aqueous paste dispersion including a flame retardant and thermoplastic adhesive dispersed therein in discontinuous pattern onto one surface of the paper. After removal of water, the drying temperatures is increased to activate the thermoplastic adhesive to adhere to the surface of the tissue with the flame retardants solids dispersed within the interior of the tissue paper. The adhesive coated tissue paper has good acoustic properties and imparts flame retardancy to a laminate including it.Type: GrantFiled: August 20, 2001Date of Patent: November 16, 2004Assignee: Harodite Industries, Inc.Inventor: Frank C.
