METHOD AND DEVICE FOR MANUFACTURING WAIST PART OF WEARABLE ARTICLE
A method for manufacturing an around-torso portion of a worn article, including the steps of; intermittently conveying a plurality of first sheets by a first drum; conveying a preceding second sheet, of a plurality of second sheets, toward a junction with the first drum by a first pad of a second drum, and conveying the preceding second sheet so that the male touch fastener at the rear end of the preceding second sheet overlaps with the female touch fastener at the front end of one first sheet, of the plurality of first sheets; and conveying a subsequent second sheet, of the plurality of second sheets, toward the junction with the first drum by a second pad of the second drum, and conveying the subsequent second sheet so that the male touch fastener at the front end of the subsequent second sheet overlaps with the female touch fastener at the rear end of the one first sheet.
STERILIZABLE WIRELESSLY DETECTABLE OBJECTS FOR USE IN MEDICAL PROCEDURES AND METHODS OF MAKING SAME
Various embodiments of wirelessly detectable objects to be used in medical procedures are provided. Such may employ ionizing radiation hard wireless radio frequency identification (RFID) transponders, other wireless transponders and/or integrated circuits, and attachment structures, all of which retain structural and functional integrity when exposed to standard sterilization dosages of ionizing radiation. Additionally or alternatively, the wireless radio frequency identification (RFID) transponders, other wireless transponders and/or integrated circuits, and attachment structures, may retain structural and functional integrity when exposed to standard sterilization temperatures and/or pressures.
Elastic composite sheet manufacturing method
An elastic resin material having a thermoplastic elastic resin as a main component is heated and melted, and the elastic resin material is discharged in a film or a linear shape from a discharge mechanism to form a film-shape or a linear-shape intermediate product. At a temperature above the temperature region at which the elastic resin material elastically deforms, extending is performed until the thickness or width of the film-shape intermediate product or the thickness of the linear-shape intermediate product assumes a prescribed value; with a cooling roller, the intermediate product is cooled to the temperature region at which the elastic resin material elastically deforms, and the intermediate product is hardened, forming a film-shape or linear-shape elastic member. The elastic member is stretched with a stretch roller to a prescribed stretching ratio, and the stretched elastic member is laminated on and bonded to a first base material sheet.
ABSORBENT ARTICLE WITH REUSABLE BELT AND METHODS FOR MANUFACTURING THEREOF
A method for forming a wearable absorbent article may comprise forming, by a system, an absorbent chassis comprising an absorbent core, a first lateral end, a second lateral end, and a length in a longitudinal direction extending between the first lateral end and the second lateral end. The method may further comprise forming, by the system, a reusable belt, and attaching, by the system, the belt to the absorbent chassis via at least one temporary fastener component formed on at least one of the absorbent chassis or the belt, resulting in formation of a wearable absorbent article unit.
ABSORBENT ARTICLE WITH REUSABLE BELT AND METHODS FOR MANUFACTURING THEREOF
An absorbent article comprises an absorbent chassis and a belt. The absorbent chassis comprises an absorbent core, a first lateral end, a second lateral end, and a length in a longitudinal direction extending between the first lateral end and the second lateral end. The belt comprises a continuous ring of at least one material configured for wear around a waist of a wearer that is operatively engageable with the first lateral end and the second lateral end, wherein at least a portion of the continuous ring is expandable, wherein the absorbent chassis is disposable, and the belt is reusable with and re-attachable to one or more additional absorbent chassis.
METHOD OF PRODUCING ABSORBENT BODY FOR ABSORBENT ARTICLE, AND ABSORBENT ARTICLE
A base sheet having one main surface applied with an adhesive is supplied to a conveyance device and the base sheet is conveyed while the other main surface of the base sheet is suctioned. A first laminate is formed by overlapping the one main surface of the base sheet with the other main sheet of a fiber sheet having one main surface nap-raised; then, a granular absorbent material is scattered on the one main surface of the fiber sheet; the scattered absorbent material is infiltrated into the fiber sheet when the other main surface of the base sheet is suctioned; then, a second laminate is formed by overlapping the one main surface of the fiber sheet with the one main surface of a cover sheet applied with an adhesive; and then the resultant sheet is compressed in the thickness direction by means of a compression means and the applied adhesive.
Underpants-type disposable diaper
A waist portion W has a first portion P1 and a second portion P2 each including a waist elastic member. The first portion P1 includes an over sheet layer folded back at an edge of a waist opening WO extending to an inside of a waist inner sheet layer. The over sheet layer is formed of a sheet material having a portion folded back at an edge of the waist opening WO from a position outside the waist elastic member in the second portion P2 and extending to a position inside the waist elastic member in the second portion P2. In the first portion P1, the waist elastic member is not fixed to the sheet material. In the second portion P2, the waist elastic member is fixed to the sheet material, and the sheet material is contracted in a width direction WD together with the waist elastic member.
ABSORBENT ARTICLES AND METHODS OF MAKING
An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core such that each said channels are surrounded by absorbent material wherein said top layer of the core wrap is in direct contact with the topsheet, and wherein said top layer of the core wrap comprises a spunbond nonwoven or a carded thermobonded nonwoven.
ABSORBENT ARTICLE
An absorbent article comprising an absorbent core comprising absorbent material. The absorbent core is sandwiched between a liquid-permeable upper core cover layer and a lower core cover layer. The absorbent core has one or more elongated areas arranged therein, each elongated area being an absorbent material free area having a length as measured along the elongated area and a width. The upper core cover layer and the lower core cover layer in each of the one or more elongated absorbent material free areas are attached to each other within at least 2 attachment zones and at most 12 attachment zones, the attachment zones being spaced-apart in the longitudinal direction (Y) within each of the one or more absorbent material free areas.
METHOD AND DEVICE FOR MANUFACTURING WORN ARTICLE
A method including: a step of carrying first and second continuous webs in a carrying direction; a step of folding the continuous webs in two; a first attachment step, in which portions of first edges, which extend in the carrying direction of the continuous webs and which are to be leg holes of a worn article, are attached together intermittently in the carrying direction; a step of straightening, in a width direction, creases on one of the continuous web after the first attachment step; and a second attachment step, in which the continuous webs are attached together at least at portions along second edges opposite to the first edges, with the creases being straightened.
