A process for making a pants-type diaper without generation of waste material. The pants-type diaper is composed of a body fluid absorbent pad member 4 curved in a U-shape, a front waist member 2 and a rear waist member 3 extending around front and rear waist-halves, respectively. The front and rear waist members 2, 3 are obtained by feeding first and second elastic members in parallel to each other in a machine direction so as to describe substantially sinusoidal curves, respectively, securing these elastic members to one surface of a web fed in the machine direction and then transversely bisecting the web between the first and second elastic members. The first and second elastic members are symmetric to each other about a center line bisecting the web but phase-shifted with respect to each other in the machine direction by half a cycle of the substantially sinusoidal curve. |
