In order to enable the folding portion 202 to be stably folded along the second folding line 204, the folding device further includes a pressing plate 62, the pressing plate 62 is disposed parallel to the bottom plate 600 at an interval, the pressing plate 62 includes a side portion 621, the side portion 621 is disposed parallel to the vertical section 603 at an interval, so that the pressing plate 62 forms an L-shaped slit 620 between the pressing plate 62 and the bottom plate 600 and between the pressing plate 62 and the vertical section, when the folder 20 enters the slit 620, the pressing plate 62 abuts against the inner side of the folder 20, so that the folding portion 202 located at the outer side can be stably folded along the side portion 621, and it can be understood that the second folding line 204 is formed at a position corresponding to the side portion 621 after the folder 20 is detached from the folding device.

It is understood that the first end 601 and the second end 602 may not be disposed perpendicular to the first direction 103, and the leading end 611 is not disposed flush with the first end 601, but only the projection of the first end 601 and the second end 602 on the vertical plane is required to be disposed in a horizontal straight line, and the projection of the leading end on the vertical plane is required to be disposed in a straight line, which may also enable the folder 20 to fold the folded portion 202 onto the first portion 201 while moving along the first direction 103.

S7: fixing the folded part 202 on the first part 201 to form a body 210;

the above-mentioned fixing of the folded portion 202 to the first portion 201 can be performed by providing the adhesive layer 203 including an adhesive on the folded portion 202 or the first portion 201 when the folded portion 202 is folded along the second folding line 204 in a direction approaching the first portion 201 in step S6, and when the folded body 20 is detached from the folding apparatus, the folded portion 202 is adhered to the first portion 201 so that the folded portion 202 is fixed to the first portion 201, and it can be understood that the adhesive can be various adhesives in the prior art, and is not limited thereto.

Further, it is also possible to apply pressure to the folded portion 202 after the folded body 20 is detached from the folding apparatus, thereby making the folded portion 202 more stably bonded to the first portion 201.

In other embodiments, the adhesive layer 203 may not be provided in step S6, and after the folded body 20 is detached from the folding device, the folded portion 202 and at least a part of the region where the first portion 201 is attached are thermally fused by ultrasonic heating, and after cooling, the folded portion 202 and the first portion 201 are integrated into a whole to form the body 210.

Referring to fig. 3 and 4 together, the main body 210 is substantially fan-shaped, and the folding portion 202 is also fan-shaped, and is folded along the second folding line 204 and fixed on the first portion 201, it can be understood that the folding portion 202 is folded along the second folding line 204 on the first portion 201 to form a form in which the bottom layers 13 on both sides of the second folding line 204 are attached to each other, and when the main body 210 is unfolded along the first folding line 102, the main body 210 is in a cone-shaped three-dimensional form due to the folding of the folding portion 202.

Further, after step S7, a step of wrapping the body 210 to form the package 30 and a step of slitting the package 30 to form individual packages after the package 30 is formed may be provided.

The invention also provides a breast pad, the specific characteristics of which have been described in the above description and will not be described in detail herein.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
