A base sheet having one main surface applied with an adhesive is supplied to a conveyance device and the base sheet is conveyed while the other main surface of the base sheet is suctioned. A first laminate is formed by overlapping the one main surface of the base sheet with the other main sheet of a fiber sheet having one main surface nap-raised; then, a granular absorbent material is scattered on the one main surface of the fiber sheet; the scattered absorbent material is infiltrated into the fiber sheet when the other main surface of the base sheet is suctioned; then, a second laminate is formed by overlapping the one main surface of the fiber sheet with the one main surface of a cover sheet applied with an adhesive; and then the resultant sheet is compressed in the thickness direction by means of a compression means and the applied adhesive.

HYDRO-ENLARGED, APERTURED NON-WOVEN WEB AND METHOD OF MAKING SAME

A hydro-enlarged apertured non-woven web includes a plurality of fibers with a plurality of bond points, a first surface defining a planar top, and a second surface defining a planar bottom. The second surface is separated from the first surface by a first distance defining a loft. A plurality of apertures extending through the non-woven web. The plurality of apertures is formed by spraying a fluid against an unapertured precursor web, causing a plurality of pins disposed on a pinned roller to punch through the unapertured precursor web. The unapertured precursor web has a third surface defining a planar top and a fourth surface defining a planar bottom, where the third surface is separated from the fourth surface by a second distance defining a precursor loft. The loft is greater than the precursor loft by a loft increase within a range of 50-110%.

Apparatuses and methods for transferring and bonding substrates

A method and apparatus for mechanically deforming a substrate assembly. The substrate assembly may be advanced in a machine direction at a first velocity toward a bonder apparatus. The bonder apparatus may rotate about an axis of rotation and include a support surface between each of a first and a second member. The first member and the second member may be separated by a repitch angle. The second member may be repositioned such that the first member and the second member are separated by a product angle. The first member may receive a leading portion and second member may receive a trailing portion of the substrate assembly and each member may rotate at the first velocity. The leading portion and the trailing portion are separated by a product arc length, which may be equal to a process product pitch. The substrate assembly may then undergo one or more processes such as bonding, cutting, and/or scoring.

20170296396 · 2017-10-19 ·

A method for method for fabricating an absorbent article is disclosed. The absorbent article comprises at least a topsheet and a liquid impermeable backsheet. The method provides for the steps of: a) supplying the topsheet; b) supplying the liquid impermeable backsheet; c) affixing a measuring device to one of the topsheet and liquid impermeable backsheet; and, d) contactingly engaging the topsheet and liquid impermeable backsheet so that the measuring device is disposed therebetween when the topsheet and liquid impermeable backsheet are disposed in contacting engagement.

Apparatuses and methods for transferring and bonding substrates

A method for mechanically deforming, such as by bonding, a substrate assembly. The substrate assembly may be advanced at first velocity toward a bonder apparatus. The bonder apparatus may rotate at a second velocity, which is less than or equal to the first velocity. The bonder apparatus may include a support surface and a process assembly. The substrate assembly may be contracted prior to advancing onto the bonder apparatus. A first process assembly may receive a leading portion of the substrate assembly and a subsequent process assembly may receive a trailing portion. The leading portion and the trailing portion define a product arc length, which is less than or equal to a process product pitch. One or more processes may be performed on the substrate assembly. The substrate assembly may then be removed from the apparatus and advanced through a metering assembly such that the substrate assembly exits at the first velocity and may be expanded such that the leading portion and the trailing portion are separated by the process product pitch.

Apparatuses and methods for transferring and bonding substrates

A method for mechanically deforming a substrate assembly. The substrate assembly may advance at a first velocity toward a bonder apparatus. The bonder apparatus may rotate about an axis of rotation and include a support surface between a first member and a second member. The first and second members may rotate at the first velocity and may be separated by an initial angle. The first member may receive a leading portion and the second member may receive a trailing portion of the substrate assembly. The first member may decelerate to a second velocity, and, subsequently, the second member may decelerate to the second velocity. The first member and the second member may be separated by a process angle, which may be different than the initial angle. A central portion of the substrate assembly may be relaxed while the leading and trailing portion may be held at a process tension. The substrate assembly may then undergo one or more processes.
