Disposable diaper with elastic complex and manufacture method of disposable diaper

Abstract

The invention provides a disposable diaper with an elastic complex and a manufacture method of the disposable diaper. An intermittent mode instead of a traditional full-spray sizing mode is adopted bysheet fixing glue which is used for fixing an outer-layer sheet material and an inner-layer sheet material, wherein the elastic complex is formed through compounding of elastic threads, the outer-layer sheet material and the inner-layer sheet material, and the non-sizing areas of the elastic threads in the elastic complex are cut through a cutting device; and the cutting device is of a structurein which a slender miniaturized cutter module and a cutter mandrel are separated, and blades of the cutter module are arranged in a linear and angular mode so that each elastic thread can pass throughat least two of the blades in the cutting process. The cutters of the cutting device are arranged on surface of the inner-layer sheet material, and the cutting depth is between the inner-layer sheetmaterial and the elastic threads, so that the elastic threads are cut, and the appearance beauty of the outer-layer sheet material 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
