Abstract

The present invention relates to the field of disposable hygienic products, in particular to a process for applying S elastics to pull-up pants, comprising the following steps: the first step, the bottom non-woven fabric is input, and the bottom non-woven fabric has a plurality of continuous In the area of ​​the formed pull-up pants, use the curved elastic composite device to composite the first curved elastic and the second curved elastic on the bottom non-woven fabric; in the second step, use the reinforcing roller device to roll the composite bottom non-woven fabric After pressing and rolling, the first reinforcement points are respectively formed at the left side of the back waist, the upper half of the crotch, the lower half of the crotch, and the right side of the front waist at the first curved elastic band; the third step, Use a point-breaking device to point-break the rolled bottom non-woven fabric. The fourth step is the output of the bottom non-woven fabric. The invention solves the technical problems that the existing pull-up trousers S elastics are easily wrinkled and twisted in products in production, and wrinkled and damaged in formed products.
