A method of manufacturing a composite body of a sheet-like member of an absorbent article, the method includes: holding a first sheet-like member on a holding surface of a holding section; and delivering and attaching the first sheet-like member from the holding surface to a second sheet-like member. The first sheet-like member has a section that is to be delivered first, and a section that is to be delivered subsequently during delivery to the second sheet-like member. The first sheet-like member is held on the holding surface with suction air from a plurality of holes that have been formed on the holding surface. The holding section has at least two suction chambers. A first suction chamber is in communication with holes that suck the section that is to be delivered first, and a second suction chamber is in communication with holes that suck the section that is to be delivered subsequently.

Manufacturing method and manufacturing equipment of composite body of sheet-like member of absorbent article

A method of manufacturing an absorbent article includes forming a pair of side flap-folded sections by folding a continuous sheet such that end sections in a width direction of the continuous sheet are folded inwardly in the width direction, while the continuous sheet is being transported in a continuous direction of the continuous sheet, producing a flap segment by segmenting the continuous sheet at a predetermined pitch in the continuous direction, joining the flap segment to a continuous body of absorbent main bodies in an overlapped manner, while the continuous body of absorbent main bodies is being transported in a transport direction corresponding to a continuous direction of the continuous body, and dividing the flap segment into a section having the pair of first side flaps and a section having the pair of second side flaps by segmenting the continuous body of absorbent main bodies.

Apparatus and method of manufacturing an absorbent article

In a step of performing a stretching process performed by using an embossing roll mechanism, a continuous body of an exterior sheet is conveyed in a state in which strand-shaped members are joined with each of an end region and an end region of the continuous body of the exterior sheet, along a conveyance direction of the continuous body of the exterior sheet; and the strand-shaped members joined with the end region are sandwiched by tooth units of a first embossing roll and interdental units of a second embossing roll corresponding to the end region side, and the strand-shaped members joined with the end region are sandwiched by the tooth units of the first embossing roll and the interdental units of the second embossing roll positioned at the end region side.

Method of manufacturing disposable diaper

A nozzle assembly configured to form one or more adhesive lines extending in a machine direction on an upper surface of a fibrous web continuously running in the machine direction has first, second and third working regions arranged in this order from upstream toward downstream in the machine direction. The first working region is adapted to come in close contact with the fibrous web fully in a width direction of the fibrous web. The second working region including first partitioning regions is arranged intermittently in a cross direction orthogonal to the machine direction and adhesive outlets each defined between each pair of the adjacent first partitioning regions. The third working region includes second partitioning regions arranged intermittently in the cross direction downstream of the first partitioning regions and stepped regions each defined between each pair of the adjacent second partitioning regions.

In a case where components such as side flaps and crotch portions are arranged on multiple webs which are being conveyed while being arranged side by side in the width direction of the webs, articles in various sizes can be handled easily by a web conveying step of conveying a front waistline webA and a back waistline webB the webs being arranged side by side in a width direction of the webs, a flap attaching step of attaching side flapsonto the webof the front waistline webA or the back waistline web, a web gap changing step of changing a gap between the front waistline webA and the back waistline webB by a web gap changing mechanismand a crotch member attaching step of attaching a crotch memberbetween the front waistline webA and the back waistline webB, wherein the web gap changing step is performed between the flap attaching step and the crotch member attaching step.

Method and apparatus for manufacturing absorbent article

A method for manufacturing an absorbent article includes joining, one longitudinal end portion of a main absorbent body base material to a back-side band base material and another longitudinal end portion of the absorbent body base material to the abdominal-side band base material, folding the main absorbent body base material and overlapping the back-side band base material with the abdominal-side band base material, temporarily joining the overlapped back-side band base material and abdominal-side band base material cutting the temporarily joined back-side band base material and abdominal-side band base material and forming a back-side band base material piece and an abdominal-side band base material piece, and transporting the back-side band base material piece, the abdominal-side band base material piece and the main absorbent body base material in a transport direction with the back-side band base material piece and the abdominal-side band base material piece in a temporarily joined state.

Method for manufacturing absorptive article

An apparatus that manufactures an absorbent article includes a rotating member that rotates in a state where the rotating member is opposing one face of a continuous sheet that is moving, the rotating member having an arcuate retaining surface that retains a work, the rotating member causing the work to be moved to a position where the work is nipped between the one face and the arcuate retaining surface by rotating in a state where the work is retained on the arcuate retaining surface; and a pressing member that bonds a continuous sheet and a work together by coming into contact with another face of the continuous sheet when the work reaches the position and pressing the continuous sheet towards the arcuate retaining surface.
