METHOD OF MANUFACTURING DISPOSABLE DIAPER

摘要

A method of manufacturing disposable diapers having a structure in which the position of an absorption core of a disposable diaper is not displaced from the center between a pair of leg elastic members. The method has a sheet member manufacturing process (P1) in which elastic members are joined in a stretched state to a sheet continuously supplied in a machine direction (MD) to form belly side and back side sheet members (20, 30), a joining process (P2) in which absorptive panels (4) are joined to the belly side and back side members at constant intervals, the absorptive panels (4) each having a pair of crotch elastic members (42) attached in a stretched state along opposite long sides of an oblong shape of the absorptive panel (4) and also each having absorptive cores (5) joined to the absorptive panel (4) so as to be symmetrical about an imaginary center line bisecting the distance between the pair of crotch elastic members (42), and a cutting process (P3) for cutting the belly side and back side sheets to which the absorptive panels (4) are joined.
