Patent ID: 8221572

Claim:
A method of manufacturing an absorptive article provided with that includes a pair of leg opening portions, a crotch portion between the pair of leg opening portions in a transverse direction of the absorptive article, and an elastic member extending between the leg opening portions across the crotch portion, said method comprising: placing a continuum of the elastic member in a desired layout, on a surface of a web being transported continuously in a machine direction, while swinging the continuum of the elastic member in a cross direction crossing the machine direction; feeding the web on which the continuum of the elastic member is placed, between a first roll, which is rotating in the machine direction, and a second roll; and pressing and bonding the continuum of the elastic member to the web between the first roll and the second roll, wherein said first roll has a recess formed in a predetermined pattern on an outer peripheral surface of the first roll, and a non-recess region formed on the outer peripheral surface of the first roll, said recess and non-recess region arranged sequentially in the machine direction as the first roll rotates, and wherein said recess is arranged corresponding to the continuum of the elastic member placed in a first area corresponding to the crotch portion on said surface of the web; said non-recess region arranged corresponding to the continuum of the elastic member placed in a second area corresponding to at least one of the leg opening portions on said surface of the web, and the continuum of the elastic member and the web are pressed between the first roll and the second roll, so that the continuum of the elastic member placed in the first area corresponding to the crotch portion on said surface of the web faces the recess on the outer peripheral surface of the first roll and is therefore not bonded to the web in the first area.
