Disposable diaper with elastic composite and its manufacturing method

Abstract

The invention provides a disposable diaper with an elastic composite body and a manufacturing method thereof. The sheet fixing glue adopts an intermittent method instead of the traditional full-spray glue application method to fix the outer layer sheet and the inner layer sheet. The elastic thread is compounded with the outer layer sheet and the inner layer sheet to form an elastic composite body, and the elastic thread in the elastic composite body is cut in the non-glue area of ​​the elastic thread through a cutting device. The cutting device adopts a slender and miniaturized cutter module separated from the cutter mandrel. The blades of the cutter module are arranged in a linear and angular manner so that each elastic wire can pass through at least two blades during the cutting process. The cutting device sets the cutting knife on the surface of the inner layer sheet, and the cutting depth is from the inner layer sheet to the elastic thread, so that the elastic thread is broken, so the appearance of the outer layer sheet is not damaged.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment for disposable sanitary products, in particular to the fields of baby pull-up pants, adult pull-up pants, sanitary pants, etc., and specifically relates to a disposable diaper with an elastic composite and a manufacturing method thereof. Background technique [0002] Disposable diapers, especially pull-up pants, no matter the three-piece style or the two-piece style, are usually composed of two parts: the outer covering layer S0 (exterior) and the inner sheet S1 (interior). The inner sheet S1 is directly wrapped with the one-piece outer covering layer S0 to form a two-piece pull-up pants. The split-type outer covering S0 (which can be divided into two parts, the abdomen and the buttocks) and the inner sheet S1 form a three-piece pull-up pants. Now take the traditional three-piece style pull-up pants as an example, as shown in Figure 1, it is a three-piece product, the outer coveri...

Problems solved by technology

In addition, since the first area K1 and the second area K2 have relatively large ranges, if the pressures of the corresponding dotted blades U in the cutting device are inconsistent, different degrees of cut marks are likely to occur on the surface of the outer layer sheet W1, and some It may even cut through the outer sheet W1, forming a large opening, which greatly affects the appearance of the product
