Bonding apparatus and method
The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface 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 surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.
Breathable structural web and breathable structural web-forming apparatus
A breathable structural web includes a layered structure having at least a layer of a non-woven material. The layered structure includes a base layer portion that has opposite first and second sides, a plurality of hollow protrusions that are disposed at the first side and that protrude and that are tapered from the base layer portion in a first direction, and a plurality of indented portions that are disposed at the second side, that extend from the base layer portion in a second direction opposite to the first direction, and that respectively define a plurality of recesses which open in the first direction. The hollow protrusions are scattered among the indented portions.
ABSORBENT ARTICLE WITH CHANNELS AND METHOD FOR MANUFACTURING THEREOF
An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core being positioned in between said topsheet and said backsheet; said absorbent core having a first and second longitudinal edge (131, 132) and a front and rear transverse edge (133, 134), wherein the absorbent core is provided with a plurality of attachment zones where the top core wrap sheet is attached to the back core wrap sheet, wherein the plurality of attachment zones comprises: at least a first and a second elongate attachment zone, said first and second elongate attachment zone extending next to each other from a crotch region in the direction of the front and/or rear transverse edge; at least one connecting attachment zone connecting said first attachment zone with said second attachment zone.
SHAPED PERMEABLE MATERIAL COMPOSITE FOR USE IN AN ABSORBENT ARTICLE
A permeable material composite is provided for use in an absorbent article. The permeable material composite includes a permeable material layer that is a low-strength material layer and having a tensile strength of less than 3 N/mm. The permeable material layer has an edge having a contour and being a shaped edge providing the permeable material composite with a non-rectangular shape. The permeable material layer is reinforced along the shaped edge with a reinforcement material that is attached to the permeable material layer. The reinforcement material has a shaped outer edge having a contour that coincides fully or partly with the contour of the shaped edge of the permeable material layer.
METHOD FOR MANUFACTURING MEDICAL SPONGE FOR ORTHOPEDIC TREATMENT BY UNILATERAL PRESSING
Provided is a method for manufacturing a medical sponge for orthopedic treatment by unilateral pressing, which relates to compaction of medical sponges. The method includes a pressing machine that includes a bottom bracket, two vertical support rods, a middle support, a U-shaped support, a drive assembly and two film pressing assemblies. The two vertical support rods are fixed vertically on both ends of the bottom bracket, respectively. The middle support is fixedly arranged on a middle of an upper side of the bottom bracket, and the U-shaped support is fixedly arranged on a top of the middle support. The drive assembly is fixedly arranged on the U-shaped support. The two film pressing assemblies are fixedly arranged between two outer sides of the U-shaped support and the two vertical support rods, respectively.
APERTURED NONWOVEN WEB AND METHOD OF FORMING THE SAME
A nonwoven web with apertures, suitable for use in a disposable absorbent article, is disclosed. Also disclosed is a method of producing a nonwoven web with apertures. The nonwoven web comprises greater than 50%, by weight of the web, of thermoplastic fibers. Each of the aperture is defined by an opening in a first surface of the nonwoven web and a side wall. The side walls of the apertures have a mean height of less than 460 μm. Also disclosed is an absorbent article comprising the nonwoven web. A topsheet, backsheet, or other component of the absorbent article may comprise the nonwoven web.
Disposable absorbent article and absorbent core composite or construction for incorporation therewith, components therefor or thereof, and systems, apparatus and methods of making the same
Improved absorbent core components including multiple layers configured to enhance fluid handling properties. The layers include absorbent material layers, with or without absorbent material-free lanes. The layers also include nonwoven layers, including air-through nonwovens, bulkified nonwovens, slitted nonwovens, and bulky nonwovens.

Elastic laminate and process for the manufacture of elastic laminate
An elastic laminate including a first nonwoven layer, a second nonwoven layer, and a plurality of elastic strands arranged in parallel with one another between said first and second nonwoven layers is disclosed, as well as a process for the production of the laminate. The elastic laminate includes elastic strands that are stretched and individually coated with an adhesive. The first and second nonwoven layers are attached to the stretched elastic strands to provide a corrugated elastic laminate when the elastic strands are relaxed. At least one of the nonwoven layers is attached to the strands at distinct adhesive bonding points in a repeating predetermined pattern in a lengthwise direction along the strands to form a predetermined corrugation pattern, and the nonwoven layers are substantially free of adhesive, except in the adhesive bonding points where the layers are attached to the elastic strands.
Prestretched elastic film in personal hygiene products
Stretched elastic films include a polyolefin, a styrene block copolymer, a non-styrene block copolymer, or a combination thereof. Methods for forming polymeric films and articles of manufacture prepared therefrom are described.
