Shaping technology of elastic waistline of waist-surrounding paper diaper

Abstract

The invention discloses a shaping technology of an elastic waistline of a waist-surrounding paper diaper. The shaping technology is realized through the following steps of (1) decoiling rubber bands and non-woven cloth; (2) gluing the rubber bands and the non-woven cloth; (3) folding in half; (4) recombining; (5) cutting off the rubber bands, and sending a compound body of the step (4) into a rubber band cutting-off knife rest to implement breakpoint cut-off on the rubber bands in a part of area of the compound body, wherein in cutting, the rubber band breakpoint areas are respectively the same with that of the part, coinciding with an absorption core body, of the elastic waistline of the paper diaper; the space between every two adjacent rubber band breakpoint areas in the longitudinal direction of a semi-finished product is the same with that between the rear end part of the absorption core body and the rear end part of the elastic waist line of the paper diaper; (6) spraying glue onto the surface; (7) cutting off and changing the direction. Compared with the prior art, the shaping technology can enable the shaped elastic waistline to be of a breakpoint structure corresponding to the rubber band at the absorption core body of the paper diaper, so that the elastic waistline has no an elastic effect corresponding to the absorption core body; therefore the elastic waistline does not cause the core body to wrinkle without losing the original function.

Description

technical field [0001] The invention relates to a forming process of diapers, in particular to a forming process for elastic waistline of ring-waisted diapers. Background technique [0002] There are many varieties of traditional diapers, but most diapers have poor elasticity, are not suitable for babies when worn, and excrement is easy to leak. There is a kind of adjustable tightness diapers on the market, such as figure 1 As shown, its specific structure includes a diaper body and an elastic waist arranged at the rear end of the diaper body. The absorbent core between the woven surface layer and the air-permeable bottom film has a first distance between the front end of the absorbent core and the front end of the non-woven surface, and the rear end of the absorbent core and the non-woven surface There is a second distance between the rear ends of the elastic waist, the elastic waist is within the second distance, and the front end of the elastic waist extends forward to ...

AI Technical Summary

Problems solved by technology

However, because the front end of the elastic waist is overlapped with the rear end of the absorbent core, the rear end of the absorbent core at the overlapping position of the elastic waist will be wrinkled due to the contraction characteristics of the elastic waist, and the wrinkle The wrinkled part is in contact with the baby's buttocks, which makes it more uncomfortable for the baby to wear
