Disclosed is a method for producing an absorbent article, which comprises a sheet heating step (S20) in which a composite sheet (120) is heated with a heating roll (510), and a sheet stretching step (S30) in which the composite sheet (120) is stretched in the cross direction (CD) with a pair of embossing roll mechanisms (520). In the sheet heating step (S20), the composite sheet (120) is heated to a temperature that is higher than the softening point of an adhesive material but lower than the lowest softening temperature among the softening temperatures of the plurality of sheets. In the sheet stretching step (S30), a plurality of projections constituting the embossing roll mechanisms (520) are heated to a temperature higher than 40°C but lower than the softening point of the adhesive material.為了提供一種吸收性物品之製造方法,可將複數個薄片藉由黏著材貼合而成之複合薄片,以不致發生損傷的方式朝寬度方向均一地延伸,並提供吸收性物品之製造方法所使用的延伸裝置。本發明之吸收性物品之製造方法,係具備:藉由加熱輥(510)來加熱複合薄片(120)之薄片加熱步驟S20、以及藉由一對的模壓機構(520)來將複合薄片(120)朝交叉方向CD延伸之薄片延伸步驟S30。在薄片加熱步驟S20,是將複合薄片(120),以比黏著材的軟化點高且比複數個薄片的軟化溫度當中最低的軟化溫度更低的溫度進行加熱。在薄片延伸步驟S30,是將構成模壓輥機構(520)之複數個凸部,以比40度高且比黏著材的軟化點低之溫度進行加熱。20...背面薄片20E...緣部分21...延伸部21A...中央延伸部分21B...端部延伸部分22...未延伸部30...吸收體S1...前胴周圍區域S2...後胴周圍區域S3...胯下區域C1...中央區域C2...側部區域C3...緣部區域C4...緣部區域
