Patent ID: 7407557

Claim:
A method for producing a disposable wearing article, comprising the steps of: producing an elastic strip material by sandwiching two elastic members between two webs under a stretched state in a longitudinal direction of the webs in such a way that the elastic members are at positions apart from a widthwise center of the webs; halving the elastic strip material in a center area between the elastic members so that protrusions and recesses alternately appear to thereby define a first elastic strip and a second elastic strip; separating the first elastic strip and the second elastic strip from each other in a widthwise direction; shifting the first elastic strip from the second elastic strip in the longitudinal direction so that the protrusions of the first and second elastic strips come into the same phase to define aligned pairs of protrusions, the protrusions in each of the aligned pairs of protrusions being spaced apart in the widthwise direction; attaching absorbers onto respective predetermined parts of the first and second elastic strips so that the absorbers lie over the protrusions in each of the pairs of the first and second elastic strips; wherein after or before the step of halving the elastic strip material, less shrinking force parts are formed on the two elastic members at portions corresponding to the respective protrusions of the first and second elastic strips.
