Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an absorbent material for disposable diapers, and particularly to an absorbent material in the crotch area of an M diaper, in which the absorbent material is formed into a thick layer.

Conventionally, disposable diapers that have been put into practical use are made by interposing an absorbent layer made of pulverized pulp between a water-permeable top sheet and a water-impermeable back sheet. In the hourglass-shaped diaper, the width of the absorbent body in the inseam area of the diaper is narrowed by 1,000 mm. Since the amount of absorbent wood is reduced by that amount, the amount of excreted liquid absorbed is reduced by that amount, and as a result, excreted liquid may enter the layer of the diaper from the side edge of the crotch area. Therefore, as an hourglass-shaped absorbent body, one formed in the crotch area 11-thick layer is preferable.

An object of the present invention is to provide a device that can easily form the above-mentioned preferred absorbent body.
- The gist of the present invention is to slit both toothed portions of a strip-shaped continuous absorbent material at regular intervals in the length direction so that the folded portion and the non-folded portion are mutually aligned in the length direction. a11 cutter to form the folding 11it-, a guide device that folds the folding 11it inwardly, and retracting the non-folding portion to a non-folding action area within the guide so that the non-folding portion is not folded by the guide @. The suppressor that is pressed down as much as possible and the non-folding part II-
The present invention resides in an apparatus for forming a diaper absorbent body which removes mold by t%, and includes a second cutter that performs cutting in the width direction.

1: Furthermore, implementation a of the present invention is illustrated as an example. To clarify,
There is a guideline below.

The absorbent material for one diaper is thus formed. Incidentally, it goes without saying that the absorbent garment is one in which the crotch area of the diaper is narrow and thick, as intended by the present invention.

Therefore, according to the device of the present invention, the intended purpose can be achieved.19. Since the simple guide device 1 and the pressure prediction are placed in the Q#, there is no need to damage the absorbent material 111 (i (+1 [+1)].
