Abstract:
The present invention relates to absorbent articles, such as diapers and sanitary napkins, and cores useful for such articles. More specifically, the invention relates to an absorbent article having a longitudinal centerline and a transverse centerline, the absorbent article comprising an absorbent core, the core comprising a storage layer and a wearer facing side oriented towards a wearer when the article is being worn and an opposed garment facing side, the absorbent article further comprising a liquid pervious topsheet on the wearer facing side of the core and a liquid pervious backsheet on the garment facing side of the core, the core further comprising a first core wrap sheet covering the wearer facing side of the storage layer and a second core wrap sheet covering the garment facing side of the storage layer the first core wrap sheet being joined to the second core wrap sheet along at least one transverse stripe of juncture, wherein the stripe of juncture covers a total area and the stripe of juncture provides a bond strength of at least 1 N/cm between the first core wrap sheet and a second core wrap sheet as measured as tensile strength in the longitudinal direction and wherein the stripe of juncture comprises an open area of at least 20% of the total area.
Abstract:
A method of producing an absorbent article, including: metering particles at a predetermined flow rate to form a metered particle stream; carrying the metered particle stream in a carrier flow to form a carried particle stream; pulsing the carried particle stream to form a pulsed particle stream; and transferring a pulse from the pulsed particle stream onto a forming surface of the absorbent article.
Abstract:
A method of producing absorbent articles, comprising: suspending particles in a gas carrier to form suspended particles; creating a series of pulses from the suspended particles, wherein each pulse in the series of pulses is created by: accumulating at least some of the suspended particles in a pulsing chamber to form accumulated particles on a rotary separator, and releasing at least some of the accumulated particles by rotating the rotary separator to create each pulse; and suctioning each pulse from the series of pulses onto a forming surface for the absorbent articles.
Abstract:
A method for making a disposable absorbent core comprises depositing absorbent particulate polymer material from a plurality of reservoirs in a printing roll onto a substrate disposed on a grid of a support which includes a plurality of cross bars extending substantially parallel to and spaced from one another so as to form channels extending between the plurality of cross bars. The plurality of reservoirs in the first peripheral surface are arranged in an array comprising rows extending substantially parallel to and spaced from one another. A disposable absorbent article and apparatus for making an absorbent article are also disclosed.

The support and printing roll are arranged such that the plurality of cross bars are substantially parallel to the rows of the plurality of reservoirs and the absorbent particulate polymer material is deposited on the substrate in a pattern such that the absorbent particulate polymer material collects in rows on the first substrate formed between the first plurality of cross bars. A thermoplastic adhesive material is deposited on the absorbent particulate polymer material and the substrate to cover the absorbent particulate polymer material on the substrate and form an absorbent layer. A disposable absorbent article and apparatus for making an absorbent article are also disclosed.
