Abstract:
1. A method for making a disposable pants-type diaper comprising: the steps of preparing a basic structure having a crotch region, a front waist region extending forward from said crotch region and a rear waist region extending rearward from said crotch region, bonding said front and rear waist regions to each other along transversely opposite margins of said front and rear waist regions to make said basic structure in a pants-shape and providing said basic structure on its inner side facing the wearer's skin with s separator adapted to prevent feces from coming in contact with the wearer' skin, said method for making the disposable pants-type diaper further comprising the steps of: preparing a separator extending on said inner side of said basic structure in a back-and-forth direction of said crotch region from a longitudinal middle of said crotch region into said front and rear waist regions, and extending in a transverse direction of said crotch region so as to straddle a longitudinal center line bisecting a transverse dimension of said crotch region; fixing transversely opposite margins of said separator extending in said back-and-forth direction to said inner side on both sides of said longitudinal center line, and spacing a region of said separator defined between said transversely opposite margins; folding back said basic structure in said back-and-forth direction along a transverse center line with said separator inside and then integrating a front end of said separator extending in parallel to said transverse center line with a rear end of said separator extending in parallel to said transverse center line on said longitudinal center line; and bonding transversely opposite margins of said front waist region to the transversely opposite margins of said rear waist region in said basic structure to form said separator from said separator.
