Patent number: 6823571Abstract: Apparatus for manufacturing multi-layer metal feedstock material for stamping shaped parts eliminates the need for rolls of metal at the stamping site. Multilayer metal feedstock material is assembled from multiple rolls of metal stock, then folded in a zig zag fashion, or “Z-fold” configuration, whereby the multilayer metal assembly is stacked vertically, usually on conventional pallets, for ease of moving with a forklift or otherwise. The multilayer metal z-fold stack of material is then transported to a parts stamping operation where the material is used as it unfolds as a continuous feed to machines to produce shaped multilayer metal parts. This invention is most useful in making multilayer metal foil z-fold feedstock material and using the z-fold material as continuous feed to processes for making shaped multilayer metal foil parts. The layers may have non-metal layers of material, such as fiber, between the metal layers or on the outside of the metal layers.Type: GrantFiled: January 24, 2000Date of Patent: November 30, 2004Assignee: ATD CorporationInventors: G.

The die-cut sheet is preferably in the form of a sheet of double-faced or double-wall corrugated board including 30 to 55 flutes/30 cm at a height of 2.3 to 5 mm and a takeup ratio of 1.30 to 1.65, with the liner and the medium having basis weights of 150 to 350 g/m2 and 120 to 200 g/m2, respectively. The box can be used as a paper container for photo-sensitive materials.Type: GrantFiled: August 6, 1997Date of Patent: February 20, 2001Assignee: Fuji Photo Film Co., Ltd.Inventors: Mutsuo Akao, Takashi Yoneyama

Patent number: 6083580Abstract: A container having walls made of a paper/plastic laminate having a cardboard core sandwiched between inner and outer face liners, wherein at least one of the face liners is comprised of a face liner laminate. The face liner laminate is composed of an exterior ply of oriented synthetic plastic film whose opposing surfaces are rendered wettable by corona-discharge treatment, and a base paper ply is cold-laminated to the film ply and adhered to the core of the board. The cardboard core may be a fluted medium of corrugated paper board, or it may be a planar stiff paper core. The invention is also directed to a structural member for use in making inexpensive furniture comprising a supporting member and a cardboard core laminated to a face liner laminate. The film ply of the laminate enhances the strength of the container or structural member and imparts water resistance thereto. Because the exposed surface of the film ply is printable, it may have decorative graphics or other printed matter applied thereto.Type: GrantFiled: April 20, 1998Date of Patent: July 4, 2000Inventors: Arnold B. Finestone, Gilbert Bloch

Patent number: 6015601Abstract: The present invention relates to a self-sealing flexible plastic valve for a non-latex balloon, to a balloon incorporating such a valve, to a method of manufacturing such a valve, and to a method of manufacturing a balloon incorporating such a valve. The valve is made from two flexible plastic strips, bonded together along the side edges to define a valve passageway or tube, and having an open inlet end and an open outlet end. The inlet end of one or both valve strips flares or otherwise curls outwardly to facilitate opening of the valve to insert a gas supply mechanism to inflate the balloon.Type: GrantFiled: August 7, 1998Date of Patent: January 18, 2000Assignee: Convertidora Industrial S.A. de C.V.Inventor: Arturo Verduzco Garcia

Patent number: 5907917Abstract: A display and panels include corrugated or fluted sheet material having display and support surfaces in which a plurality of cut-outs or slits are made in one or both surfaces so as to make the material rollable. The plurality of slits are in the same axis as the corrugations or flutes, and may be formed by means of a cutting tool adapted to slit or cut the corrugated or fluted sheet material. A guide can control the one or more blades of the cutting tool into contact with the one or more respective corrugations or flutes.Type: GrantFiled: October 23, 1997Date of Patent: June 1, 1999Inventor: Robert Laurence Bicker

Patent number: 5763041Abstract: A laminate suitable for use as the hook component of a hook-and-loop fastener. The laminate comprises a first extensible substantially non-elastic layer and a second layer comprising a nonwoven material. The nonwoven material is prebonded by a number of first spaced-apart bond sites to form first bonded and first unbonded areas. The second layer is attached to the first layer by a plurality of second spaced-apart bond sites to form a bulked laminate having a plurality of second bonded and second unbonded areas. The second bonded and second unbonded areas together define a surface area of said bulked laminate with said second bonded areas covering from about 5 to about 20 percent of the surface area. At least 50 percent of the second bonded areas have an area of less than about 4 square millimeters and have a density of greater than about 2 bonds per square centimeter.Type: GrantFiled: December 21, 1995Date of Patent: June 9, 1998Assignee: Kimberly-Clark Worldwide, Inc.Inventors: A. Todd Leak, Mark Michael Mleziva, Duane Girard Uitenbroek, Monica Signoret Diaz, Lance James Garrett, Jr.

Patent number: 5750235Abstract: A base board for a layered corrugated fiberboard structure comprises a corrugated fiberboard material including a corrugating medium having flutes, first folds along which the corrugated fiberboard material is folded in the shape of the inverted letter V, and second folds along which the corrugated fiberboard material is folded in the shape of the letter V, and the first folds and the second folds are formed in the corrugated fiberboard material in parallel to each other and in an alternate arrangement so as to extend perpendicularly or at an angle other than a right angle to the flutes. The second folds are lines of perforations, and portions of the corrugated fiberboard material that forms an outer surface when folded are incised along the lines of perforations.Type: GrantFiled: November 12, 1996Date of Patent: May 12, 1998Assignees: Yokoyama Sankoh Co., Ltd., Hitachi Zosen CorporationInventor: Yokoyama Yoshimasa

Patent number: 5747140Abstract: A completely vented upholstered body of grid plates with a wave profile includes solid portions of the grid which pass through the wave extrema of its wave contour. Many of the solid portions of the grid preferably are disposed transversely to at least one wave propagation direction and, in each case, continuously over a large portion of a wavelength, at a distance from one another. There is only a limited, specified bending deformation, during which the solid portions of the grid can be deformed largely independently of one another as if they were individual spiral springs. As a result, the upholstered body has a high point elasticity despite the plate construction. By adroit dimensioning of the course of the wave thickness, an advantageous diffusion of stresses can be achieved without stress peaks. Moreover, the work of deformation is absorbed uniformly in the upholstered material. This results in a long service life of the upholstered body.Type: GrantFiled: March 22, 1996Date of Patent: May 5, 1998Inventor: Siegfried Heerklotz

Patent number: 5681641Abstract: A structural member formed from a billet, each member comprising a plurality of corrugated paperboard sheets bonded together with an adhesive and disposed between a core fiber layer, each core fiber layer comprising at least one ply of a fiberboard sheet, a pair of caps of a solid fiberboard sheet bonded to respective side faces of the paperboard sheet and to the respective edges of the core fiber layers. A method of manufacture is disclosed in which the billet is built up of corrugated paperboard sheets. The billet is then ripped into planks for use as a plank, board, or cleat, particularly as components for corrugated paperboard containers. A pallet made of planks and a pallet made of planar sheets cut from the billet are disclosed.Type: GrantFiled: June 21, 1996Date of Patent: October 28, 1997Assignee: North American Container CorporationInventors: John M. Grigsby, Jeffrey C. Banks, John M. Grigsby, Jr.
