US Patent:

51850524, Feb 9, 1993

Filed:

Jun 6, 1990

Appl. No.:

7/534055

Inventors:

Charles W. Chappell - West Chester OH
John J. Angstadt - Cincinnati OH

Assignee:

The Procter & Gamble Company - Cincinnati OH

International Classification:

B31F 122

US Classification:

156462

Abstract:

Disclosed is an apparatus for longitudinally pleating a moving lamina. The apparatus features a curved axis roll having a stationary axis circumscribed by a rotating sleeve with a plurality of circumferentially oriented grooves in the rotating sleeve. The pleats are produced by the intermeshing of the lamina with the grooves of the rotating sleeve. Preferably a complementary curved axis roll having lands which interdigitate with the grooves of the first roll is used in conjunction with the first curved axis roll. The apparatus preferably further comprises a third curved axis roll disposed upstream of the first curved axis roll to substantially equalize the paths of travel of any points on the moving lamina by compensating for differences in the paths of travel between the edges and centerline of the lamina. The apparatus may further comprise two straight axis rolls disposed outboard of the curved axis rolls and spatially arranged so that the paths of travel of either edge of the lamina and the centerline of the lamina through the apparatus and from the first straight axis roll to the second straight axis roll are substantially equal.

International Classification:

B32B 104

US Classification:

428 76

Abstract:

A package including a web material that exhibits an elastic-like behavior along at least one axis when subjected to an applied and subsequently released elongation. The web material includes a strainable network having at least two visually distinct regions of the same material composition. The first region undergoes a molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the web material is subjected to an applied elongation in a direction substantially parallel to the axis of elongation.

International Classification:

A61F 1315

US Classification:

604387

Abstract:

The present invention relates to absorbent articles such as sanitary napkins worn by women. More particularly, the present invention relates to absorbent articles, such as thin sanitary napkins, that are stretchable, especially in the longitudinal direction.

International Classification:

A61F 1315
A61F 1320

US Classification:

604367

Abstract:

The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels.

International Classification:

A61F 1315
A61F 1354

US Classification:

604383

Abstract:

The present invention provides absorbent articles, especially sanitary napkins, containing a flow regulator positioned between the topsheet and the absorbent core. In-use, fluid deposited on the topsheet is internally moved in the longitudinal direction by the flow regulator before being released to the absorbent core. By moving substantial amounts of fluid in the longitudinal direction the flow regulator provides a more effective use of the absorbent core.

International Classification:

B29C 5904
B29C 6902

US Classification:

264557

Abstract:

A method for hydraulically deforming a web of polymeric film while the film is supported on a moving forming structure to produce a novel microbubbled substantially fluid-impervious web exhibiting substantially the same consumer preferred soft and silky tactile impression and reduced noise generation levels heretofore only achievable in microapertured, and hence substantially fluid pervious polymeric webs. In a particularly preferred embodiment, the microbubbled polymeric web exhibits a fine-scale pattern of discrete mushroom shaped surface aberrations, each of said surface aberrations having its amplitude oriented substantially perpendicular to the surface in which the surface aberration originates. The method may also be utilized to produce fluid pervious microapertured webs which are known in the art. Apparatus for producing microbubbled and/or microapertured webs either in "planar" or "macroscopically expanded" form are also disclosed.
