An anvil roll is configured to operatively engage with a tooling agent. The anvil includes an outer surface, an opposing surface opposite the outer surface and an inner surface. One or more spring elements are disposed between the opposing surface and the inner surface. The springs provide a compliance to the anvil.

Methods of making disposable absorbent articles are herein. The method includes the steps: obtaining a carrier web; obtaining first absorbent core web and a second absorbent core web; cutting the first absorbent core web in a nesting configuration thereby forming a plurality of discrete first absorbent cores; cutting the second absorbent core web in a nesting configuration thereby forming a plurality of discrete second absorbent cores; joining a discrete second absorbent core to a discrete first absorbent core and to the carrier web, thereby forming a laminate structure web, wherein a leading edge of the discrete first absorbent core is spaced from a leading edge of the discrete second absorbent core in the machine direction; joining a backsheet web to the laminate structure web thereby forming an absorbent article web; and cutting the absorbent article web into a plurality of discrete absorbent articles.

An anvil is configured to operatively engage with a tooling agent. The anvil includes an outer surface, an opposing surface opposite the outer surface and an inner surface. One or more spring elements are disposed between the opposing surface and the inner surface. The springs provide a compliance to the anvil.

Disposable absorbent articles are disclosed herein along with method of making the same. The disposable absorbent article has a topsheet, a backsheet, and an absorbent system between the topsheet and the backsheet. The absorbent system has a first absorbent core and a second absorbent core which are offset from one another. An adhesive layer is disposed between the first absorbent core and the second absorbent core, at least in part.

A flexible curvilinear knife is disclosed. The flexible curvilinear knife is formed from a cutting element, a blade holder element, and a plurality of spring elements. A first, proximal end of each spring element of the plurality of spring elements is operably and fixably attached to a discrete location of the cutting element and a second, distal end of each spring element of the plurality of spring elements is fixably attached to a discrete location of the blade holder element.

A flexible bonding roll including one or more pressure applying members is configured to operatively engage an anvil roll. The one or more pressure applying members include one or more spring elements. The spring elements allow for the one or more pressure applying members to compress as the pressure applying members are engaged by the outer circumferential surface of the anvil roll. The compression of the pressure applying members allows for relatively reduced damage of substrates and equipment during bonding.

Processes for making micro-textured webs are disclosed. The present process includes the steps of providing a precursor web; providing a first pair of mated forming members including a first forming member and a second forming member forming a first deformation zone therebetween; moving the precursor web through the first deformation zone forming a first plurality of structures; providing a second pair of mated forming members including a third forming member and a fourth forming member forming a second deformation zone therebetween; moving the precursor web through the second deformation zone forming a second plurality of structures, and wherein the first plurality of structures is different than the second plurality of structures.

Process for making a micro-textured web

A formed web comprising discrete three-dimensional elements formed therein, wherein at least some of the discrete three-dimensional elements comprise chads with corresponding apertures, wherein the aperture has a perimeter, wherein the chad has a length, wherein the chads are attached along a portion of the aperture perimeter which forms a connection segment, wherein the connection segment is less than about 50% of the entire aperture perimeter, and wherein the web comprises a film.

Formed web comprising chads

Processes for making micro-textured webs. The process comprises providing a precursor web; providing a pair of mated forming structures, including a first forming structure and a second forming structure, wherein at least the first forming structure comprises voids, and wherein at least the second forming structure comprises protrusions; and moving the web through a deformation zone of the mated forming structures, wherein the voids of the first forming structure engage with the protrusions of the second forming structure at an engagement position. Discrete three-dimensional elements are formed in the web as the protrusions on the second forming structure engage with the voids on the first mating structure. At least one protrusion has center-to-center spacings of less than about 800 microns with at least three of its adjacent protrusions.

Included are systems and methods for modeling compliant parts. Some of the systems and/or methods include creating a 3-dimensional simulation of a product that includes an outer part and an inner part, determining a deformation characteristic of the product, and simulating an interaction of the inner part with the outer part. Similarly, in some of the systems and/or methods a characteristic of interaction may be measured from the interaction, a determination may be made regarding whether the characteristic of interaction meets a predetermined threshold. In some of the systems and/or methods, in response to determining that the characteristic of interaction meets the predetermined threshold, an output may be sent indicating product design acceptability. In response to determining that the characteristic of interaction does not meet the predetermined threshold, the 3-dimensional simulation may be iteratively altered until the characteristic of interaction meets the predetermined threshold.

Systems and methods for modeling compliant parts

Apparatus for making micro-textured webs. The apparatus comprises a pair of mated forming structures having a first forming structure, a second forming structure, and a deformation zone; wherein at least the first forming structure comprises voids, and wherein at least the second forming structure comprises protrusions wherein at least one protrusion has center-to-center spacings of less than about 800 microns with at least three of its adjacent protrusions. The voids of the first forming structure are engagable with the protrusions of the second forming structure at an engagement position to form a micro-textured web. In another embodiment, the apparatus comprises a pair of counter-rotating rollers wherein the first roller comprises grooves having a length, wherein the length of the grooves are oriented at an angle different from the machine direction.

Apparatus for making a micro-textured web

A system for controlling the strength of seals imparted to workpiece layers by a sealing roll and an anvil roll, the sealing roll and the anvil roll arranged on opposing sides of a conveyed web of workpiece layers, heating elements provided on at least one of the rolls, temperature sensors provided on the at least one of the rolls, and a controller in communication with the sensors and in operable communication with the heating elements. The sealing roll includes a textured sealing surface, the textured sealing surface being divided into a plurality of regions, the texture of a first of the regions being different from a texture of a second of the regions. By controlling the temperature of the respective regions, detrimental effects of anvil wear on the strength of the seal imparted to the workpiece layers may be offset, increasing the service life of rolls.
