Apparatus and method of manufacturing an elastic composite structure for an absorbent sanitary product

An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes a bonding unit configured to bond a first web layer to a second web layer via a bond pattern that includes at least one bond line having at least one pair of adjacent bonds. The bonding unit secures an elastic thread within a passage defined by the at least one pair of adjacent bonds. The passage has a cross-sectional area smaller than a cross-sectional area of the elastic thread in a non-tensioned state.

An incontinence underwear including a crotch area hosting a stitching, a first layer, a second layer, a third layer, a fourth layer, a fifth layer, a sixth layer, and a seventh layer, wherein the first layer is innermost, wherein the seventh layer is outermost, wherein the second layer extends between the first layer and the third layer, wherein the fourth layer extends between the third layer and the fifth layer, wherein the sixth layer extends between the fifth layer and the seventh layer, wherein the stitching extends through the first layer, the second layer, the sixth layer, and the seventh layer, wherein the stitching avoids extending through the third layer, the fourth layer, and the fifth layer, wherein the second layer is bonded or adhered to the third layer.

ABSORBENT ARTICLE

An absorbent article includes a topsheet comprising a composite sheet. In the composite sheet, projections that protrude toward the skin of the wearer are formed by a first sheet protruding in a direction away from a second sheet at portions other than bonding portions. A plurality of first oblique bonding portion rows and a plurality of second oblique bonding portion rows are formed, and a long bonding portion elongated in a longitudinal direction is formed at each intersection of the first oblique bonding portion rows and the second oblique bonding portion rows. Laterally long projections elongated in a width direction are formed in a dispersed manner in the longitudinal direction and the width direction. Each laterally long projection is surrounded by two first oblique bonding portion rows and two second oblique bonding portion rows, and the long bonding portion is formed between adjacent laterally long projections in the width direction.

FLEXIBLE DEMOLDING DEVICE, CORE MOLDING DEVICE, AND CORE FORMING METHOD
20240225912 · 2024-07-11 ·

A flexible demolding device, comprising a flexible substrate and a driving device. A plurality of forming holes are provided on the flexible substrate and penetrate through the thickness direction of the flexible substrate. The driving device drives the flexible substrate to move continuously in a defined direction. The driving device comprises a driving wheel, a supporting wheel and a conveying belt which is sleeved between the driving wheel and the supporting wheel. The flexible substrate is fixed on the conveying belt. On one hand, the demolding assembly no longer has a rigid structure. On the other hand, since the flexible substrate can be fixed on the conveying belt by means of the connecting body, the flexible substrate can be easily replaced.

Bonding Apparatus and Method
20180318143 · 2018-11-08 ·

The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll having three or more pattern elements protruding radially outward, wherein each pattern element includes a pattern surface. The pattern surfaces are also separated from each other by gaps having minimum widths. The pattern roll may be adjacent an anvil roll to define a nip between the pattern surfaces and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surfaces and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surfaces to form a discrete bond region between the substrates. During the bonding process, some of yielded substrate material also flows from under the pattern surfaces and into the gaps to form gap grommet regions.

ABSORBENT ARTICLES COMPRISING A LAYERED FLUID ACQUISITION/DISTRIBUTION SYSTEM AND METHODS FOR MAKING SAME

Absorbent articles, for example baby diapers and/or training pants, feminine hygiene products, such as pads, and adult incontinence pads and/or pants, and more particularly absorbent articles that include an improved fluid acquisition/distribution system and methods for making same are provided.
