A method of manufacturing a pant-type absorbent article

Abstract

The invention discloses a method for manufacturing a pants-type absorbent article. The pants-type absorbent article has an absorbent main body and an outer casing. The outer casing includes an outer layer sheet, an inner layer sheet, and a A plurality of elastic members between the outer layer sheet and the inner layer sheet. The manufacturing method of the pants-type absorbent article includes: an outer body treatment process, an inner packaging compound process, a half folding process, a product cutting process, and a waist wrapping process. Process; wherein, in the external body processing process, along the technological process, it includes: a conveying process, an elastic body compounding process, an elastic part cutting process, an exterior wrapping process, and a hook element compounding process. The present invention adopts the flow process of folding the outer sheet of the exterior continuum first, then compounding with the hook element, and then compounding with the absorbent main body, which shortens the process to a certain extent, saves the manufacturing cost, and ensures the smoothness of the process. Stability and good compounding effect, while improving the flatness of the compounding area of ​​the hook element in the outer body.

Description

technical field [0001] The invention belongs to the technical field of manufacturing equipment for disposable sanitary products, in particular to the field of baby / adult disposable diapers and the like, and specifically relates to a method for manufacturing a pants-type absorbent article. Background technique [0002] In general, pants-type absorbent articles, such as open-close disposable diaper products, usually include an absorbent main body and an outer casing. Specifically, the outer casing is arranged on the back side of the wearer, and the absorbent main body passes through the crotch from the back side. The part of the absorbent article extends to the abdomen, and the absorbent main body is joined to a part of the outer body. The pants-type absorbent article is in a "T-shape" in the unfolded state, so it is also called a T-shaped diaper; the outer body of this type of pants-type absorbent article Small protruding hook elements are respectively arranged at the left an...

AI Technical Summary

Problems solved by technology

However, for the open-close disposable diaper product, because its shape is similar to a "T" shape, in its manufacturing process, its outer body is in a state of continuous traction, there is tension between each other and the outer body is relatively thin, and the absorbent body is in a state of continuous traction. In an intermittent state and the absorbent main body is relatively thick, since the outer covering is located at one end of the absorbent main body, if the outer sheet of the outer covering is folded in this case, it will not only destroy the tension balance of the outer covering, but also make the front and back of the absorbent main body The force on the end is uneven, and if the wrapping is placed after being combined with the outer body, the main part of the absorption must be taken into account, the wrapping device will also be designed wider, and the manufacturing cost will also increase

[0004] Similarly, the recombination of the hook element is also limited by the continuity of the exterior body on one side and the discontinuity of the absorbent body on one side after the recombination of the outer body and the absorbent body, which leads to deviations in the compounding process and directly restricts the absorption of pants. The stability of the production process of sexual goods and the quality of the products

On the other hand, in the prior art, when corresponding to the hook element area, there will be more elastic parts cut into small sections between the outer layer sheet and the inner layer sheet, thus causing the composite area of ​​the hook element in the outer body to be uneven, not only Affects the composite effect of the hook element and the inner and outer nonwovens, and also affects the overall aesthetics of the pant absorbent article
