Problems solved by technology

[0004] However, in the technology described in Patent Document 1, it is difficult to match the edges of the two strip-shaped base sheets with each other. piece
In addition, in the technology described in Patent Document 1, since the excess rubber thread is cut off with a cutter outside the end of the strip-shaped basic sheet, the end of the rubber thread may be pulled from the stretchable sheet. The end of the bar extends outwards, in this case, becoming an unsightly waist flap

Embodiment Construction

[0014] Next, the manufacturing method of the absorbent article of this invention is demonstrated based on the best mode, referring drawings.

[0015] Such as figure 1 As shown, the absorbent article having the stretchable waist panels manufactured in this embodiment is, for example, an unfolded disposable diaper 1 . Therefore, first, the unfolded disposable diaper 1 (it is also called "diaper 1" hereafter) which has the stretchable waist panel 3 manufactured by this embodiment is demonstrated.

[0016] Such as figure 1 As shown, the diaper 1 comprises: an absorbent body 2 having an abdominal portion A positioned on the ventral side of the wearer when worn, a dorsal portion B positioned on the back side, and an absorbent body between the abdominal portion A and the dorsal portion B. crotch C; Such as figure 1 As shown, the diaper 1 has flap materials 4, 4 extending from both side edges of the abdominal portion A, respectively. Additionally, if figure 1 As shown, the absor...

Abstract

The present invention provides a manufacturing method of an absorbent article which is provided with waist fins (3). The fins (3) are telescopic sheets (30) which is fixed between strip-shaped sheets (50,60) through an elongation state in an X direction. The manufacturing method comprises steps of: after coiling an elastomer (7) between long structures (12,13) by an elastomer coiling mechanism (14) for line conveying, clamping the elastic member between the strip-shaped sheets (50,60); and a step of cutting off the linear elastomer (7) thereby forming the telescopic sheets (30). Besides, the manufacturing method further comprises the following steps: a dividing step of cutting off the strip-shaped sheets (50,60) at the central part; and a step of replacing the positions of the two telescopic sheets obtained through cutting, forming the waist fins (3) through cutting, jointing the waist fins (3) with an absorbent body (2) according to a mode that a cutting edge (91) extends out in an X direction of a diaper (1) for forming the diaper (1).

Description

technical field [0001] This invention relates to the manufacturing method of absorbent articles, such as a disposable diaper. Background technique [0002] From the standpoint of saving materials as much as possible, controlling the amount of waste, protecting the environment, and controlling costs, there is a kind of unfolded disposable diaper, which is to manufacture the waist flap parts with fastening belts in advance through another process, and Manufactured by adding waist panel members to a rectangular absorbent main body including an absorber. From the viewpoint of wearability, the waist panel member is preferably a stretchable member, and as the waist panel member, a member formed using a stretchable film is generally used. However, stretchable films increase the cost, so it is preferable to form the waist panel members using so-called rubber threads, which are general-purpose elastic members. However, the expansion and contraction direction of the waist panel memb...
