Absorbent articles with curved elasticized laminates

Absorbent articles having curved elasticized laminates and apparatuses and methods for forming such articles are disclosed. In one embodiment a method of forming an article may comprise moving absorbent assemblies and elasticized laminates in the machine direction. The method may further comprise oscillating the elasticized laminates in the cross-machine direction to impart a curvature, bonding the elasticized laminates to the absorbent assemblies while maintaining the imparted curvature such that at least a portion of the elasticized laminates are disposed outboard of longitudinal side edges of the absorbent assemblies, and finally separating the absorbent assemblies into individual absorbent articles, where the elasticized laminates extend in a curving manner throughout the absorbent articles.

Apparatus and method for applying parallel flared elastics to disposable products and disposable products containing parallel flared elastics

An apparatus for applying elastics to a running web including a crank and arm, the arm arranged to reciprocate from side to side during use and having a laydown carriage carried on the arm, the laydown carriage including at least one eyelet arranged to support an elastic strand, the assembly further including a shoe guide.

Methods and apparatuses for making elastomeric laminates with elastic strands provided with a spin finish

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.

Methods and apparatuses for making elastomeric laminates with elastic strands

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.

CHASSIS DESIGN FOR ABSORBENT ARTICLE

A disposable absorbent article may include a first waist region, a second waist region, a crotch region disposed between the first and the second waist regions, and a chassis having a topsheet, backsheet, absorbent core, and chassis periphery. The chassis periphery has a varying width, WV.

ABSORBENT ARTICLES WITH CURVED ELASTICIZED LAMINATES

Absorbent articles having curved elasticized laminates and apparatuses and methods for forming such articles are disclosed. In one embodiment a method of forming an article may comprise moving absorbent assemblies and elasticized laminates in the machine direction. The method may further comprise oscillating the elasticized laminates in the cross-machine direction to impart a curvature, bonding the elasticized laminates to the absorbent assemblies while maintaining the imparted curvature such that at least a portion of the elasticized laminates are disposed outboard of longitudinal side edges of the absorbent assemblies, and finally separating the absorbent assemblies into individual absorbent articles, where the elasticized laminates extend in a curving manner throughout the absorbent articles.

Elastomeric absorbent articles

The present invention includes disposable absorbent articles, such as disposable undergarment, diapers, other garments, and wound care dressings, having an elastomeric material disposed between two substrate layers and an absorbent core system that disposed on top of or between the two substrate layers. This invention may also include a disposable article having an elastomeric material disposed between two substrate layers without an absorbent core. The inclusion of an stretch adhesive in the construction of the article in various portions of the article (e.g., fastening tabs, front and/or rear sections, entire article, etc.) results in improved securement of the article to a wearer for reducing the risk of leakage and further improving comfort for the wearer. Furthermore, the inclusion of a stretch adhesive can provide a smooth contoured fit to a wearer, thereby improving appearance and self-confidence for the wearer.

Disposable floating absorbent core and disposable absorbent assembly including same, and method of making same

An absorbent article is disclosed. The absorbent article includes a core and a chassis. One or more discrete bonding zones bond the core to the chassis, and one or more unbonded zones of the core are not bonded to the chassis, forming a floating core. The core is not elastically coupled with the chassis. A method of making the absorbent article may include selectively bonding the chassis to the core at discrete bonding zones.

20230355446 · 2023-11-09 ·

This wearable article manufacturing method involves: a sheet preparation step in which an elastic sheet for forming a front abdominal part and a back part is prepared; a sheet weakening step in which the elasticity of the elastic sheet is weakened in a front weakening region, and in a rear weakening region; and an absorbent body connection step in which the front part of the absorbent body is connected to the front connection region of the elastic sheet, and the rear part of the absorbent body is connected to the rear connection region of the elastic sheet. The sheet weakening step is carried out simultaneously for the front weakening region and the rear weakening region.

Laminate(s) comprising beamed elastics and absorbent article(s) comprising said laminate(s)

The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
