Abstract: The invention relates to a method and apparatus for partitioning and/or shaping a batt by gripping the batt with resilient means or, alternatively, with resilient means and non-resilient means, and by stressing or severing the batt without the formation of compaction areas on the parted edges of the batt.

Abstract: A laminated structure, such as a disposable diaper is provided which includes elastic in the margin to provide gasketing about the legs and, if desired, an improved fit about the waist. A method is provided for placing elastic only in the areas to be gathered and removing the unused elastic. In the method stretched elastic is intermittently adhered to a web substrate along a longitudinal line at the terminating portion of the gasketed area. The elastic is then severed adjacent the adhered portions and the unused elastic is removed.

Abstract: Method and apparatus for continuously attaching an elastic member to discrete portions of a moving web to impart an elasticized character to predetermined portions of the web while preserving the inelastic character of the other portions of the web.

Abstract: A laminated structure having a marginal area with gathered and ungathered portions which provide an improved fit about a portion of the human body, said laminated structure comprising an elastic member disposed between first and second substrates of flexible gatherable material, said elastic member comprising a plurality of longitudinally extending elastic elements with the elements transversely connected over a portion of their length to define apertures and an end portion of the member comprising only longitudinally extending elements and the first and second substrates of said laminated structure being secured together through at least some of said apertures.

Abstract: A delaminatable two-ply diaper facing material is provided in which an outer ply, or layer, is made of irregularly arranged, intersecting, overlapping, mechanically interengaged, loosely assembled natural wood pulp fibers and an inner ply, or layer, contains similarly disposed natural wood pulp fibers and thermoplastic synthetic wood pulp fibers having a melting point lower than that of other fibers in the layer, the latter being in contact with and heat fused with other fibers to provide structural integrity to the inner layer, with fibers in both layers being bonded to each other by a water soluble adhesive binder.The material is prepared by bringing together the aforementioned layers, applying heat in the absence of pressure to fuse the thermoplastic synthetic wood pulp fibers in the inner layer to each other and to other fibers, introducing a water soluble adhesive binder into the two layers and then drying and curing the binder.

Abstract: Nonwoven, air-laid fabrics formed predominantly of textile length, synthetic, resilient fibers of staple length, the fabric being resin-bonded and having a density less than about 0.06 gm/cc at 0.16 lb/sq. in. load and a weight less than 3 oz/sq. yd. The fabric is resin-bonded using a bonding solution providing less than 180% solution pickup and more than 15% dry solids add-on. The fabric is used as a facing or covering for disposable diapers, sanitary napkins, incontinent pads, tampons and the like.

Abstract: A disposable diaper having a gathering means adjacent at least one edge of the absorbent panel is disclosed. In a preferred embodiment, the gathering means is defined by an elastic member having a width dimension of at least 3/8" and a width-to-thickness ratio of at least 100, which provides improved body conformity without undue application of pressure upon the skin of the wearer. The inventive concept in its broadest sense relates to the distribution of the force of gathering means over larger areas to minimize skin irritation. In certain embodiments of the present invention, our improved diaper may have a pleasing ruffled effect at the diaper edge.

Abstract: Novel amphoteric and zwitterionic betaine compounds containing at least one anion having a phosphorus-oxygen-phosphorus bond and processes for their preparation are described.

Abstract: Detergent and cleansing compositions are provided containing a pyrophosphobetaine compound and preferably at least one other surfactant.

Abstract: Method for partitioning and/or shaping a fibrous batt by gripping the batt along adjacent lines with resilient means gripping one surface and non-resilient means gripping the opposite surface and displacing said lines with respect to each other to separate the batt without compacting the parted edges of the batt.

Abstract: A disposable diaper having an absorbent batt with an intermediate portion of reduced width and elastic means adjacent to each side of the batt and generally parallel therewith. The intermediate portion of the batt preferably is offset toward one end of the diaper, and may include relatively short rectilinear batt side segments. Further batt side segments extend outwardly at an angle from the ends of the rectilinear batt side segments, and still further rectilinear batt end segments extend outwardly from the ends of the inclined batt side segments.

Abstract: Apparatus for partitioning and/or shaping a fibrous batt by gripping the batt along adjacent lines with resilient means gripping one surface and non-resilient means gripping the opposite surface and displacing said lines with respect to each other to separate the batt without compacting the parted edges of the batt.

Abstract: A disposable diaper having a resealable tape tab fastener in which a first securing tape ribbon has a free end and a fixed end which is attached to the diaper. A second securing tape ribbon has a free working end, and a fixed end which is adhesively but releasably attached to the free end of the first securing tape ribbon. One face of the second securing tape ribbon is provided with an adhesive coating. The free end of the first securing tape ribbon is adapted to secure the diaper about an infant by adhesive attachment via the adhesive-coated face of the second securing tape ribbon. The free end of the first securing tape ribbon is separable from the fixed end of the second securing tape ribbon to permit the opening of an applied diaper for inspection, and to make the adhesive coating on the free end of the first securing tape ribbon available for use in refastening the diaper about the infant.

Abstract: A disposable diaper having improved fit about the legs and/or waist of the wearer and having reinforced corners for enhanced securement of the diaper about the wearer is disclosed. Improved fit and reinforcement are obtained by an elongated, inherently elastic ribbon member positioned along at least one margin of the diaper. The ribbon member is secured to the diaper so as to provide an elastic region at a central portion of the margin and a unitary, relatively inelastic reinforced region in a corner portion of the diaper.

Abstract: An improved disposable diaper containing a shaped absorbent pad. The pad has an indentation disposed along each long side nearer one end of the pad than the other. The front half of each indentation is arcuate and the back half of each indentation is triangular in shape. The sides of the pad immediately adjacent the indentations in the central portion of the pad are parallel to the center longitudinal line.

Abstract: An infant development toy comprising a plurality of rings of varying diameter connected to each other and to a central object by a flexible connecting means. Optionally, the connecting means may be extended outside the rings to form a primary handle and a bell may be contained within the central object or the primary handle. The rings and central object are of a size, and are spaced along the connecting means in such a manner that, when the toy is held aloft by and suspended from the point of connection of the largest ring and the connecting means, the rings are concentric and surround the central object.
