に１両側縁部に糸ゴムが一体に添接されている。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an improvement in a method for manufacturing disposable disposable diapers. (Prior art and its problems) This type of disposable paper diaper is made of Disposable diapers are widely used in which a water absorbing layer such as paper cotton is laminated on top of the cloth, and this water absorbing layer is covered with a non-woven fabric. A rubber thread is integrally attached to the part.

に緊張状態で密接させて固着している。In order to attach this rubber thread during the manufacture of disposable diapers, a guide member (C) having a guide groove (k) for the rubber thread has traditionally been used as shown in Figures 4 and 5. The hot melt glue solution is supplied into the guide groove () through the hollow interior of the guide member (c), and the hot melt glue solution is applied to the lower circumference of the running rubber thread (2). The rubber threads 4 are immediately fixed under tension to the upper surfaces of both sides of the poly-I film that is running.

る。However, according to such a means, even if the hot melt glue is intermittently supplied, a portion of the hot melt glue remains in the guide groove Φ) of the guide member (Q), causing the hot melt glue to flow into the yarn j/, B). As a result, the thread rubber (2)) adheres to the film over a predetermined length, and if the thread 2ts is cut at each length interval of the disposable diaper afterwards, the Although it is desired to arrange the rubber threads 4 in a contracted state only in the central portions of both sides, there is a drawback that the paper diaper contracts over the entire length, making it impossible to obtain the desired product and lowering the commercial value.

が弱くなるとい□う問題点があった。Furthermore, since a large amount of net melt paste adheres to the lower circumference of the rubber thread 4, the high heat of this net melt paste will partially melt and damage the poly-I film, resulting in defective products. In addition, there was a problem in that the adhesion to the nonwoven fabric was weak due to the small amount of net melt glue attached to the upper layer of the ``Dumu Itotaku''.

ものである。In the method for manufacturing a disposable diaper, thread is attached to the upper surface of both sides of the film, and a water-absorbing layer is superimposed on the upper surface of the central part of the film, and then covered with a nonwoven fabric. This method is characterized by adhering the rubber thread to the film by spraying a net melt glue solution at regular intervals of the rubber thread while the rubber thread is being held, thereby improving the adhesion between the rubber thread and the film and nonwoven fabric. At the same time, in the post-process, when cutting the parts that are not coated with hot melt glue for each fixed length dimension,
The structure is such that the rubber thread shrinks to obtain the desired paper diaper.

When attaching the rubber thread to the film, hot melt adhesive is sprayed onto the rubber thread at regular lengths to adhere the rubber thread to the film, so it is possible to accurately and easily apply only the length of the rubber thread that you want to adhere to the film. It is possible to attach a hot melt glue liquid, and therefore, it is possible to manufacture an excellent paper diaper in which there is no rubber thread at all in the four corners and a bag layer of rubber thread is only in the center portions of both sides,
In addition, the hot melt paste liquid is sprayed in a mist form to the yarn 5 th to,
, ft+, which enables reliable adhesion between the film and the nonwoven fabric, and eliminates damage to the film caused by the heat of the hot-melt glue, resulting in a disposable diaper with excellent commercial value. .
