Patent number: 6238504Abstract: The present invention relates to a method of applying adhesive to corrugating media to produce corrugated materials by foaming the adhesive with air prior to application to the flute tips of the corrugating media. The foamed adhesive requires less precise control of the applicator rollers, and remains in place on the flute tips, rather than migrating into the flute valleys. As a result, the same volume of adhesive can be used with decreased solids content, decreasing overall adhesive cost and increasing corrugator productivity. In addition, because of the more precise placement of the adhesive on the tips of the flutes, a stronger, higher quality board can be produced. The adhesive can be starch-based, and can be foamed by a variety of methods, such as in existing pin-rotor stator containing foaming machine used for foaming latices.Type: GrantFiled: July 22, 1998Date of Patent: May 29, 2001Inventors: Raymond C.

Patent number: 6062723Abstract: The invention provides a process for the preparation of a starch based glue for making corrugated board. The process is carried out in a system which includes a first and relatively large mixing vessel containing a stirrer. A second and smaller mixing vessel is connected to the first vessel via a recirculation path. The second and smaller mixing vessel contains means for exerting a shearing force which is greater than the shearing force exerted in the first and larger mixing vessel. The process is carried out in two steps. A first step is to make a carrier by combining water, starch and a limited amount of lye in the large vessel. A second step adds further amounts of starch, water, borax, and a second shot of lye to the carrier while in the small vessel. Adding lye in two steps is a principal aspect of the invention. If all lye is added in one step, it must be limited to an amount which does not prematurely gelatinize the starch to a level which defeats the glue making.Type: GrantFiled: June 16, 1999Date of Patent: May 16, 2000Assignee: Serco HollandInventors: Anton de Valk, William van der Zanden

Patent number: 5609711Abstract: A method whereby a significantly pregelatinized starch bearing adhesive composition may be used for bonding two laminae such as corrugated board or other panel products. A feed stream of essentially ungelatinized starch is sent to an application device. There it is significantly gelatinized within the application device and applied to the substrate laminae. The adhesive at the time of application is no longer a liquid, but is a partial gel, a gel, or a thermally melted composition. The adhesive is extruded onto the substrate as a multiplicity of parallel beads or as a full width ribbon. Temperature of the melted starch composition may be reduced prior to extrusion to limit puffing or expansion of the extrudate. The resulting laminae may be pressed tightly face to face or they may remain somewhat spaced apart by the beads of adhesive. The method allows the use of both refined and unrefined starch bearing materials to be used in the adhesive composition.Type: GrantFiled: December 18, 1995Date of Patent: March 11, 1997Inventor: Ray R.

Patent number: 5114509Abstract: A method and apparatus for starch adhesive bonding of paper, paperboard, and natural cellulosic-fiber materials, especially liner and fluted corrugating medium, into manufactured items, particularly corrugated board. The method includes applying an adhesive coating, comprising starch and water, to a first substrate (e.g. tips of flutes of a corrugated medium), contacting the applied coating with another substrate (e.g. liner) and while so positioned contacting an exterior surface of at least one of the substrates with an ultrasonic energy generating means so as to transmit the ultrasonic energy to the adhesive coating to increase coating adhesion to the substrates.Type: GrantFiled: April 15, 1991Date of Patent: May 19, 1992Assignee: Battelle Memorial InstituteInventors: Herbert N. Johnston, Donald F. Hiscock, Ralph E. Beard

Patent number: 5080936Abstract: A method for the formation of a proteolipid membrane based on interphase peptides according to which an interphase peptide which has formed at the boundary of an aqueous phase and a nonpolar phase of organic solvent is brought into contact with an assembly of amphiphilic compounds such that the nonpolar surfaces of the interphase peptide and of the assembly of amphiphilic compounds face each other. In addition to peptide, the membrane also contains lipid.Type: GrantFiled: August 9, 1988Date of Patent: January 14, 1992Inventor: Erik A. Cerwen

Patent number: 5035941Abstract: A multilayer laminate comprising: (a) a substrate layer of fibrous material; (b) an intermediate layer of polymeric material which is free of anti-static material and is extrusion laminated to the substrate layer; and (c) an outer layer of polyethylene containing anti-static material and including low density polyethylene and linear low density polyethylene, which is coextruded with and extrusion laminated to the intermediate layer. Also disclosed is an appertaining process for making a multilayer laminate. The laminate of the invention has particular utility in the fabrication of protective garment articles, for use in applications involving exposure to flammable or explosive environmental constituents which are susceptible to ignition by static discharge.Type: GrantFiled: August 22, 1989Date of Patent: July 30, 1991Assignee: Abandaco, Inc.Inventor: William A. Blackburn

Patent number: 5015677Abstract: An adhesive or coating formulation useful in biomedical application and particularly well suited for use in aqueous environments is provided comprising:(1) a bioadhesive polyphenolic protein component having from about 5 to about 99 weight percent of a proteinaceous substance comprising from about 10 to about 400 of the following repeating decapeptide unit: ##STR1## in which each X is hydrogen or hydroxyl and each R is hydrogen or methyl; (2) from about 1.0 to about 40 weight percent of a cross-linking agent which promotes cross-linking of the decapeptide;(3) one or more additives which promote the desired properties of the formulation, said additives comprising at least one surfactant and being present in an amount of from 0% to about 90% by weight, and(4) a filler compatible with the intended use of the formulation, said filler being present in an amount of from 0% to about 50% by weight.Type: GrantFiled: June 27, 1988Date of Patent: May 14, 1991Assignee: Bio-Polymers, Inc.Inventors: Christine V. Benedict, Paul T. Picciano

Patent number: 4978411Abstract: This invention presents starch-based alkaline corrugating adhesives having improved green bond strength due to the use of undried starch as the raw starch component in the adhesive. Such adhesives can be used in corrugation processes at much higher corrugator running speeds than the conventionally employed adhesives.Type: GrantFiled: January 16, 1990Date of Patent: December 18, 1990Assignee: National Starch and Chemical Investment Holding CorporationInventors: Craig Leake, Michael Foran, Jeffrey G. Atkinson

Patent number: 4972018Abstract: An adhesive of starch, an ammonium-based latex and ammonium zirconium carbonate improves the hot, green bond properties of the adhesive formulation for paperboard and corrugated board. The latexes are typical styrene-butadiene and carboxylated styrene-butadiene latexes but untypically are polymerized in the presence of a volatile base such as ammonium hydroxide.Type: GrantFiled: December 19, 1988Date of Patent: November 20, 1990Assignee: The Dow Chemical CompanyInventor: Arthur N. Leadbetter
