  • Patent number: 7754041
    Abstract: A pleated filter is made from a monocomponent monolayer nonwoven web containing a bimodal mass fraction/fiber size mixture of intermingled larger size and smaller size continuous monocomponent polymeric fibers of the same polymeric composition. Rows of pleats are formed in the nonwoven web, and the pleated web is cut to a desired size and shape to provide a filter element containing a self-supporting porous monocomponent monolayer matrix of fibers bonded to one another at at least some points of fiber intersection and having an average initial submicron efficiency of at least 15% at a 1.52 meters/sec face velocity. The filter element is deformation resistant without requiring stiffening layers, bicomponent fibers or other reinforcing measures in the filter media layer.

  • Patent number: 7608318
    Abstract: The invention can be defined in its most general form as a building unit, namely the sandwich panel with light core from corrugated sheet material in the form of zigzag crimp, and can be used in aircraft construction, as well as in shipbuilding and construction. Making use of the claimed invention will improve the weight efficiency, the strength and the manufacturability of the panel. The beneficial effect is attained due to the fact that the plane slanting ridges are connected along the protrusion and recess zigzag lines by means of curvilinear parts, whose radius is not less than the core material thickness, whereby along said parts is a line perforation enabling the adhesive material to get into the holes of the perforation in the course of core-skins assembling.

Using these series patterns, the material can be cut, folded and the parts created in a manner such that the individual parts forming a single filler are releasably attached to one another, thus resulting in effective and efficient organization of these parts. The filler panels can then be arranged into a folding stack of offset edges. Two shapes are preferably used with subtle differences between each at the fold area. Different patterns can be used to have the first two panels in the series positioned at 0 degrees, followed by two panels positioned at 45 degrees, and then alternating the angle positions throughout the pattern. The pattern preferably incorporates triangular portions or tabs between each set of panels in the series to help in establishing a fold line.

  • Patent number: 7361241
    Abstract: In order to produce a nonwoven fabric having elastomeric properties spun filaments (1), consisting preferably (but not essentially) of cellulose material such as cellulose acetate or solvent spun rayon, not in yarn formats, are corrugated or crimped in an overfeed process, as in stuffer box (6), into stabilized three dimensional batts. A proportion of filaments (3) of a thermal memory material, such as modified polyester, in a stretched format are included. The resulting batt is then subjected to controlled hydroentangling and a controlled heat treatment to yield three dimensional nonwoven fabrics with elastomeric properties due to contraction of the stretched filaments. Elastomeric memory material activated to shrink by ultrasonic treatment may be used in place of thermal memory material. The elastomeric properties can be adjusted to suit end-use requirements and applications are envisaged in the medical and hygiene areas.

  • Patent number: 7132031
    Abstract: In a process for making disposable diapers, a first web is continuously fed in its longitudinal direction. Tape fastener members extending in the longitudinal direction are fed to the first web so as to straddle respective lines corresponding to the side edges of the respective backsheets. Each of the tape fastener members has its longitudinally opposite end portions folded in a Z-shape or an inverted Z-shape. Top sections of these Z-shape and inverted Z-shape are coated on their undersides with a first self adhesive and bottom sections of these Z-shape and inverted Z-shape are coated on their undersides with a second self-adhesive. The tape fastener member is bonded to the first web by means of the second self-adhesive. The first web and the tape fastener members are simultaneously cut along the lines.

  • Patent number: 7087130
    Abstract: A method for manufacturing a bag for use in vacuum packaging comprises forming a first panel having a receiving feature and a second panel having an insertion feature, such that the insertion feature can be removably connected with the receiving feature, thereby forming a zipper. Each panel comprises a gas-impermeable base layer and a heat-sealable inner layer molded from melt-extruded resin. The first panel is overlapped with the second panel, and three of four edges of the panels are heated such that the inner layers bond at the heated edges and the unbonded edge can be opened or closed via the zipper. Optionally, the bag can include a valve structure for evacuating the bag. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

  • Patent number: 7077925
    Abstract: Method of fitting products with stretchable sleeves. A stretchable sheath is placed on a reel by forming a tubular sheath made from a stretchable plastic material of the dimension required to fit the product, flattening the sheath whilst forming a gusset in each side of the contour to reduce the width of the flattened sheath, and winding the sheath onto a reel. The stretchable sleeves are placed on the products by unreeling the sheath with its gussets, aligning the sheath with the production line, feeding the flat sheath into the cutter in order to cut a sleeve, and picking up the cut sleeve in order to place it on the product.

  • Patent number: 7077924
    Abstract: A method for producing tapes in pairs for the manufacture of closing tapes for baby diapers. The tapes are formed mirror-symmetrically and secured on the baby diapers in pairs. The method comprises the following steps: a web of material is separated in four strips, whereby two strips are processed as plane support tapes. The two other strips are guided via reversing stations over the support tapes and folded to form release tapes that each comprise a short leg and a long leg. Closing tapes that comprise male or female closing elements for a mechanical self-closure, are laminated to the support tapes in the direction of transport of these support tapes. The release tapes are applied to the support tapes in the direction of transport, whereby the short leg is glued to the support tape, and the long leg at least partly covers the closing tape that has been applied to the support tape. There is also a device for producing the tapes using the method described above.

  • Patent number: 7070668
    Abstract: The present invention provides a method and apparatus for producing individual folded labels from a ribbon of labels designed to satisfy the aforementioned needs. The label is formed by first providing a ribbon of labels with at least one folded over portion and then subjecting the folded ribbon to heat and pressure to set the fold. The folded pressed ribbon is then subdividing into individual labels. In an alternative embodiment, the folded and pressed ribbon can be rerolled and shipped to an end user for use in an auto-sewing device. The present invention further includes an apparatus for carrying out this method and a finished label.

  • Patent number: 6979380
    Abstract: A method of manufacturing a disposable undergarment includes moving a web of body panel material in a longitudinal machine direction and cutting the web of body panel material along the longitudinal machine direction to thereby form a rear body panel web and a front body panel web each having a maximum rise and a minimum rise respectively. The maximum rise of each of the rear and front body panel webs is greater than the minimum rise of a corresponding one of the rear and front body panel webs. The method further includes shifting at least one of the rear and front body panel webs in the longitudinal machine direction and thereby aligning the maximum rises of the rear and front body panel webs. The method further includes separating the rear and front body panels in a lateral cross direction, such that the maximum rises of each of the rear and front body panel webs are spaced apart in the lateral cross direction and form a gap therebetween in a non-overlapping relationship.
