Abstract

Способ изготовления листообразного элемента включает этап транспортирования композиционного листа (30mf), в котором множество эластичных элементов (35a, 35a, ...) вставлены между первым листом (30mf1) нетканого материала и вторым листом (30mf2) нетканого материала и в котором множество эластичных элементов (35a, 35a, ...) закреплены при их размещении рядом друг с другом в направлении (CD), которое пересекает направление транспортирования, при этом первый лист (30mf1) нетканого материала является непрерывным в направлении транспортирования, второй лист (30mf2) нетканого материала является непрерывным в направлении транспортирования и расположен так, что он перекрывает первый лист (30mf1) нетканого материала в направлении толщины, множество эластичных элементов (35a, 35a, ...) растянуты в направлении транспортирования и проходят вдоль направления транспортирования; этап (S50) образования множества сквозных отверстий (h) в композиционном листе (30mf) посредством вдавливания вдавливаемого элемента (55p) в направлении толщины в местах, находящихся между двумя эластичными элементами (35a) и (35a), соседними в направлении (CD), в композиционном листе (30mf); этап (S60) приложения растягивающего усилия, действующего в направлении (CD), к композиционному листу (30mf) на позиции, которая находится за позицией (P51) образования сквозных отверстий, при этом позиция (P51) образования сквозных отверстий представляет собой позицию, на которой выполняют образование сквозных отверстий (h) на этапе (S50) образования сквозных отверстий; и этап (S70) выполнения обработки композиционного листа (30mf) на позиции, которая находится в направлении транспортирования за позицией (P60) приложения растягивающего усилия, при этом позиция (P60) приложения растягивающего усилия представляет собой позицию, на которой выполняют приложение растягивающего усилия на этапе (S60).A method of manufacturing a sheet-like element includes the step of transporting the composite sheet (30mf), in which a plurality of elastic elements (35a, 35a, ...) are inserted between the first sheet (30mf1) of nonwoven material and the second sheet (30mf2) of nonwoven material and in which the set of elastic elements (35a, 35a, ...) are fixed when placed next to each other in the direction (CD) that crosses the conveying direction, while the first sheet (30mf1) of nonwoven fabric is continuous in the direction of transportation, the second sheet (30mf2) is not The material is continuous in the conveying direction and positioned so that it overlaps the first sheet (30mf1) of nonwoven material in the thickness direction, a plurality of elastic elements (35a, 35a, ...) are stretched in the conveying direction and extend along the conveying direction; step (S50) of forming a plurality of through holes (h) in the composite sheet (30mf) by pushing the push-in element (55p) in the thickness direction at the points between the two elastic elements (35a) and (35a) adjacent in the direction (CD), in a composite sheet (30mf); a step (S60) of applying tensile force acting in the (CD) direction to the composite sheet (30mf) at a position which is located behind the through hole formation position (P51), wherein the through hole formation position (P51) is the position at which perform the formation of through holes (h) in step (S50) of the formation of through holes; and step (S70) of processing the composite sheet (30mf) at a position which is in the conveying direction behind the tensile force application position (P60), wherein the tensile force application position (P60) is the position at which the tensile force application is performed in step (S60).
