Abstract:
A method of joining substrate portions includes positioning the substrate portions such that the substrate portions overlap at an overlap area. The substrate portions each have a melting temperature and an outer surface. A fluid is heated to a temperature sufficient to at least partially melt the substrate portions. A jet of the heated fluid is directed from a fluid orifice onto the substrate portions at the overlap area. The heated fluid penetrates at least one of the outer surfaces of the substrate portions. The substrate portions are at least partially melted using the heated fluid. The substrate portions are compressed using a pressure applying surface adjacent the fluid orifice to join the substrate portions together at the overlap area.
Abstract:
A method and apparatus for forming a batt of particulate material which may be used in an absorbent article. The apparatus may include a vacuum zone, an air impermeable fence zone adjacent to the vacuum zone, and an air permeable fence zone adjacent to the vacuum zone. The air permeable fence zone may comprise an ambient air entry conduit in communication with an ambient air exit port. The method may include providing a laydown drum and a first web of material, positioning the first web of material substantially adjacent to the laydown drum, generating a vacuum through the laydown drum, depositing particulate matter onto the first web of material, and rotating the laydown drum.
Abstract:
An absorbent product is provided. The absorbent product includes a package having an interior space and an exterior surface; and a plurality of disposable absorbent articles disposed within the interior space of the package. Each of the disposable absorbent articles has a topsheet; a backsheet; a substantially cellulose free absorbent core located between the topsheet and the backsheet; a first waist region; a second waist region; a crotch region extending longitudinally between the first and second waist regions; and a fastening member extending laterally outward from the second waist region and adapted to releasably connect with a landing zone located in the first waist region. The absorbent product exhibits an In-Bag Stack Height of less about 80 mm as measured according to an In-Bag Stack Height Test.

Abstract:
A disposable absorbent core comprises first and second absorbent layers each comprising an absorbent particulate polymer material such that the absorbent particulate polymer material is substantially continuously distributed across an absorbent particulate polymer material area. A disposable absorbent article and method for making the absorbent core are also disclosed.
Abstract:
A method and apparatus for forming a wad of particulate material which may be used in an absorbent article. The apparatus may include a laydown drum having a plurality of vacuum zones, a plurality of fence zones, and a plurality of blow-off zones. The plurality of vacuum zones may be substantially permeable to permit vacuum air to pass through and into the laydown drum. The plurality of fence zones may be substantially impermeable to inhibit air to pass through. The plurality of blow-off zones may be substantially permeable to permit blown air to pass out of and through said laydown drum. The apparatus may also include a deposition chute for depositing particulate material on a web of material in close proximity to the laydown drum. A shield may also be attached to the deposition chute.
Abstract:
A disposable absorbent article includes a chassis and an absorbent core which is substantially cellulose free. The chassis may contain a topsheet and a backsheet. The absorbent core may be located between the topsheet and the backsheet and may include (i) a storage layer which comprises an absorbent particulate polymer material and has a wearer facing side and an opposed garment facing side, (ii) a first core wrap sheet covering the wearer facing side of the storage layer, and (iii) 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 traverse sealing zone.
Abstract:
A substantially cellulose free absorbent core comprising absorbent polymer material having a saline flow conductivity greater than about 100×10−7 cm3·sec/g and a centrifuge retention capacity of greater than about 20 g/g. A disposable absorbent article is also disclosed.

Abstract:
The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.
