International Classification:

B65H 19/14

US Classification:

242552, 2261182

Abstract:

A method of accumulating a web includes pivoting subsets of rolls to a generally vertical alignment; moving one set of rolls past the other; passing the web between the sets of rolls; moving one set of rolls past the other to engage the web; pivoting the subsets to a generally horizontal alignment; moving the web alternatively between the subsets; and moving the sets apart to accumulate the web and together to discharge the web. A web accumulator includes at least two sets of rolls. Each set of rolls has subsets of rolls. The subsets have two consecutive staggered rolls. The accumulator has a web path defined by alternating between subsets of the first set and subsets of the second set.

Abstract:

Disclosed herein are elastic laminate materials having an elastic member and at least one fibrous nonwoven web. The elastic laminate materials have highly desirably properties of extensibility and elastic recovery, and cloth-like aesthetic properties of softness and drapability. In embodiments, the elastic laminate materials may include a second fibrous nonwoven web bonded to the opposite side of the elastic member. Also disclosed herein is a process for forming the elastic laminate materials. Such elastic laminate materials are highly useful for components in or on personal care products, protective wear garments, medical care products, bandages and the like.

Abstract:

A method and apparatus for bonding and aperturing one or more fibrous webs including bonding at least one fibrous web in a bonding nip created by a rotatable bonding roll and a rotatable anvil roll and aperturing the at least one fibrous web in an aperturing nip created by a rotatable aperture roll and an anvil roll. The bonding roll has a plurality of protuberances extending from the peripheral bonding surface that define a bonding pattern and result in highly bonded regions within the fibrous web. The aperture roll has a plurality of projections extending from the peripheral aperture surface that define an aperturing pattern. The aperturing pattern substantially aligns with the bonding pattern thereby creating apertures within the highly bonded regions.

International Classification:

A61F 13/49

US Classification:

60438525

Abstract:

A method of manufacturing a leg and flap elastics composite for use in an absorbent article includes joining a leg elastic member to a web moving in a machine direction. A flap elastic member is joined to the web and spaced from the leg elastic member. The web is fed to a chopper assembly wherein portions of the leg and flap elastic members are rendered less elastic at spaced-apart intervals to define deadened portions of the leg and flap elastic members.

International Classification:

A61F 13/15
A61F 13/49
A61F 13/475

Abstract:

An absorbent article having a front waist region, a back waist region, and a crotch region extending between and interconnecting the front and back waist regions. The article comprises an outer cover, a body-side liner, an absorbent assembly between the outer cover and the body-side liner, and leg and flap elastic composites including a containment flap portion and a gasket portion. Each of the composites are attached to the liner such that one of the composites is disposed adjacent one side edge of the liner and the other composite is disposed adjacent the other side edge of the liner, each of the composites extend longitudinally from the front waist region to the back waist region, and each of the composites have a deadened portion in the front waist region or the back waist region. The article further includes a waist elastic member extending longitudinally between the deadened portions.

Abstract:

A method of manufacturing a liner/composite web for use in an absorbent article includes joining a leg elastic member to a web moving in a machine direction and joining a flap elastic member to the web. The flap elastic member is spaced from the leg elastic member. The web is folded to form a leg and flap elastics composite including an outer side edge. The web is joined to a substrate to form the liner/composite web. The liner/composite web is joined to a web of material such that the outer side edge of the leg and flap elastics composite is coterminous with one of a pair of laterally opposing side edges of the web of material.
