Abstract
(EN)
Provided is a method for producing an absorbent article comprising: a step in which a continuous body (35a) of an elastic member is arranged in an extended state between a pair of facing surfaces facing each other in continuous bodies of a first sheet-like member that is continuous in a conveyance direction; a joining section formation step in which joining sections (j) for joining the facing surfaces to each other are formed; a step in which after continuous bodies of a second sheet-like member are superimposed on the continuous bodies of the first sheet-like member, side seal sections (SS) in which the continuous bodies are welded together are formed on both sides of a position to be cut (PC) set at a predetermined pitch in the conveyance direction; and a cutting step in which cutting is performed at the position to be cut and an absorbent article (1) comprising an elastic member (35), a first sheet-like member, and a second sheet-like member is generated. In the joining section formation step, the continuous body of the elastic member is maintained in the extended state while forming the joining sections on both sides of the continuous body in a CD direction. The elastic member expands in the CD direction and is sandwiched by the joining sections on both sides after the cutting step. The joining sections at least partially overlap with the side seal sections when viewed from the thickness direction.

L'invention concerne un procédé de production d'un article absorbant comprenant : une étape dans laquelle un corps continu (35a) d'un élément élastique est disposé dans un état étendu entre une paire de surfaces opposées se faisant face dans des corps continus d'un premier élément en forme de feuille qui est continu dans une direction de transport ; une étape de formation de section de jonction dans laquelle des sections de jonction (j) destinées à relier les surfaces opposées l'une à l'autre sont formées ; une étape dans laquelle, après que des corps continus d'un second élément en forme de feuille sont superposés sur les corps continus du premier élément en forme de feuille, des sections d'étanchéité latérales (SS) dans lesquelles les corps continus sont soudés ensemble sont formées sur les deux côtés d'une position à découper (PC) réglée à un pas prédéfini dans la direction de transport ; et une étape de découpe dans laquelle une découpe est effectuée au niveau de la position à découper et un article absorbant (1) comprenant un élément élastique (35), un premier élément de type feuille et un second élément de type feuille est généré. Dans l'étape de formation de section de jonction, le corps continu de l'élément élastique est maintenu dans l'état étendu tout en formant les sections de jonction des deux côtés du corps continu dans une direction CD. L'élément élastique s'étend dans la direction CD et est enserré par les sections de jonction des deux côtés après l'étape de découpe. Les sections de jonction se chevauchent au moins partiellement avec les sections d'étanchéité latérales lorsqu'elles sont vues depuis la direction de l'épaisseur.

搬送方向に連続する第1シート状部材の連続体の対向する一対の対向面同士の間に、弾性部材の連続体(35a)を伸長状態で配置する工程と、上記対向面同士を接合する接合部(j)を形成する接合部形成工程と、第1シート状部材の連続体に第2シート状部材の連続体を重ね合わせた後に、これら連続体同士を溶着するサイドシール部(SS)を、搬送方向に所定ピッチで設定された切断対象位置(PC)の両側に形成する工程と、切断対象位置で切断して、弾性部材(35)と第1シート状部材と第2シート状部材とを有 した吸収性物品(1)を生成する切断工程と、を有する。接合部形成工程では、弾性部材の連続体を伸長状態に維持しつつ、接合部を、CD方向において同連続体の両側に形成する。切断工程の後では、CD方向に拡大した弾性部材は、両側の接合部同士で挟圧されている。厚さ方向から見ると、少なくとも接合部の一部がサイドシール部に重なる。
