Abstract

provido é um método de fabricação para uma folha composta capaz de facilmente fabricar uma folha composta compreendendo em uma direção de máquina, uma seção com alta expansibilidade e uma segunda seção com baixa expansibilidade. o método de fabricação para a folha composta (106) inclui (a) uma etapa de fixação de um membro elástico contínuo (103) estendido na direção de máquina (md) à uma primeira folha (101) conduzida na direção de máquina (md), (b) uma etapa para cortar uma parte do membro elástico contínuo (103) fixado à primeira folha (101) em intervalos na direção de máquina (md), e (c) uma etapa para, em um estado no qual o membro elástico contínuo (103) ser interposto entre a primeira folha (101) e a segunda folha (102), ligando a primeira folha (101) e a segunda folha (102) entre si.provided is a manufacturing method for a composite sheet capable of easily fabricating a composite sheet comprising in one machine direction, a high expandable section and a second low expandable section. The manufacturing method for composite sheet (106) includes (a) a step of securing a continuous elastic member (103) extended in machine direction (md) to a first sheet (101) driven in machine direction (md) (b) a step for cutting a portion of the continuous elastic member (103) attached to the first sheet (101) at machine direction intervals (md), and (c) a step for, in a state in which the elastic member A continuous web (103) is interposed between the first web (101) and the second web (102), connecting the first web (101) and the second web (102) together.
