A method for producing an elastic composite web for an absorbent sanitary article comprising a first corrugated web and a second web connected together, and at least one elastic element entrapped between said first web and said second web. The invention also relates to an elastic composite web for an absorbent sanitary article.

Method for producing an elastic composite web and elastic composite web

An apparatus for producing sanitary absorbent articles comprising at least one perforating device of at least one web intended for making sanitary absorbent articles capable of making perforated patterns spaced apart along the extension of the web, that is, in phase. The present invention also relates to a perforating process implemented in an apparatus for producing sanitary absorbent articles.

Apparatus for producing sanitary absorbent articles comprising a perforating device of a web and process

An elastic film including a plurality of parallel elastic ribbons elongated in a longitudinal direction and spaced apart from each other in a transverse direction orthogonal to the longitudinal direction, wherein the elastic ribbons are coated on at least one surface by at least one skin layer which joins the plurality of parallel elastic ribbons to each other.

Elastic film, a method for producing an elastic film, and a method for producing elastic laminates

A transversally extensible elastic laminar web including a support web having a continuous edge portion sandwiched between two corresponding edge portions of two overlapped webs and a plurality of tabs extending from the edge portion outside the two overlapped webs, wherein each tab has a respective micro-hook pad fixed to a planar surface, and wherein the planar surface of each tab has a portion which completely surrounds the respective micro-hook pad.

Transversely extensible continuous elastic laminate, and a method for producing the same

A transversally extensible elastic laminate including two continuous tab chains having respective continuous base portions sandwiched between two corresponding edge portions of two overlapped webs and a plurality of tabs extending from the respective base portions outside the two overlapped webs, wherein each tab has a respective micro-hook pad fixed to a planar surface, and wherein the planar surface of each tab has a portion which completely surrounds the respective micro-hook pad.

A composite tape comprising a first web and a second web welded together according to a welding pattern comprising a plurality of welding points arranged in arrays extending along a first direction and spaced apart in a second direction, perpendicular to said first direction, with adjacent arrays offset from each other in said first direction, and with said welding points in each array arranged in groups spaced apart in said first direction, wherein the first web has a plurality of hollow protrusions alternating with welding points, both in said first direction and in said second direction, and wherein the second web has a plurality of ribs extending along said first direction and separated from each other by said arrays of welding points.

Three-dimensional composite tape, method and apparatus for its production

A transversely extensible elastic laminar web material comprising a first and a second web material each of which defines a first and a second distal region adjacent to corresponding longitudinal side edges and a central region between the aforesaid distal regions, at least one web of elastomeric material applied to these central regions of the first and second web materials and a plurality of connection formations applied to at least one distal region of said first and second web materials and projecting from a respective longitudinal edge. In the transversely extensible elastic laminar web material, the elastomeric web material and the connection formations are interposed between said first and second web materials and are joined thereto by mechanical welds.

Extensible laminar material, in particular for sanitary articles, and relative manufacturing method

A method for producing a backsheet for absorbent sanitary articles provided with hook-and-loop fasteners, comprising the steps of: advancing a continuous web of fibrous material without support at a first speed, cutting the continuous web of fibrous material in a transverse direction so as to form sections of fibrous material, accelerating the sections of fibrous material at a second speed greater than said first speed, welding said sections of fibrous material spaced apart at constant intervals onto a continuous non-woven support web advancing at said second speed, so as to convert said sections of fibrous material into frontal tapes of loop-material for hook-and-loop fasteners, and fixing a continuous impermeable film to said continuous non-woven support web with said frontal tapes of loop-material, so as to form a continuous backsheet web provided with frontal tapes of loop-material spaced apart at constant intervals.

Method for producing a backsheet for absorbent sanitary articles and an absorbent sanitary article including this backsheet

A system including a menstrual pant and an absorbent article. The menstrual pant can have a front part; a back part; a crotch part provided so as to bridge between the front part and the back part, the crotch being utilized for fitting a sanitary napkin, a waist opening part provided in an upper edge of the front part and an upper edge of the back part, a pair of leg openings provided below both side edges of the front part and both side edges of the back part; and a lifting strip disposed along the longitudinal centerline in the rear portion. The menstrual pant can apply body-contacting pressures to the wearer's body longitudinally through the crotch of 25 g/cmto 100 g/cm. The absorbent article can have a topsheet having a body facing surface, a backsheet joined to said topsheet; and an absorbent core disposed between said topsheet. The absorbent article can exhibit a 30-minute Vertical Wicking Height of at least about 12 cm.

Menstrual pant

A disposable absorbent article with an element intended to absorb bodily exudates and a web with stems which functions as a mechanical fastener to prevent shifting of the article e.g. when affixed on underwear.

Disposable absorbent articles with improved garment fastening

An absorbent article for personal hygiene, especially a sanitary napkin, panty liner and the like, having an adhesive for securing the article to a garment of a wearer. The present invention provides adhesives with an adhesion performance less dependent from panty material types and washing habits, such as treatment with softeners and the like, thus ensuring reliable fastening on non-treated panties as well as on softener-treated panties.

Disposable absorbent articles having improved adhesive for garment fastening

A disposable absorbent article with one or more side flaps or wings, having at least one corrugated region, is disclosed. The corrugated region includes a corrugated material having a multiplicity of ridges and recesses, a release material opposed to the corrugated material, and a multiplicity of glue strips between the corrugated material and the release material. The glue strips are attached to the crests of the ridges of the corrugated material. Also, methods of fabricating a composite material including the corrugated region are also disclosed.

Disposable absorbent articles with wings having corrugated regions and methods of manufacturing thereof

Portion of a sanitary napkin

The present invention relates to a composite laminated structure comprising a substrate and an apertured layer joined together by means of a layer of an adhesive composition. The laminated structure is made extensible in designated zones by mechanical straining and the adhesive composition provides both an effective connection of the layers forming the composite laminated structure and an improved processability of the laminated structure by mechanical straining. The composite laminated structure preferably constitutes side flaps in a disposable absorbent article such as a sanitary napkin.
