The manufacturing process of the paper diaper further comprises the following steps:
s4 b: first holes in a shape like a Chinese character 'tu' are formed in the first sheet material and the second sheet material at intervals of a first distance, and a crotch of the paper diaper is formed between the two adjacent first holes.
S5: folding the first and second sheets in a running direction of the first and second sheets;
s6: forming two rows of third attachment points for edge sealing on the first and second sheets between two adjacent crotch portions in a direction perpendicular to the running direction;
s7: cutting said first sheet, said second sheet and said elastic member between two adjacent columns of said third attachment points to obtain a single finished diaper.
In the above diaper manufacturing process, the elastic member is not provided in the crotch region.
Due to the adoption of the technology, compared with the prior art, the invention has the following positive effects:

Referring to fig. 1 to 8, a manufacturing process of a diaper according to a preferred embodiment is shown, which includes:
s1: providing a first sheet, a second sheet and an elastic member 1 located between the first sheet and the second sheet, the elastic member 1 being operable in a stretched state of smaller diameter and a general state of larger diameter, the elastic member 1 preferably being an elastic band;
s2: the first and second sheets run at a first speed and the elastic member 1 runs at a second speed lower than the first speed, and the elastic member is automatically in the above-mentioned stretched state during the running process due to the speed difference between the first and second sheets and the elastic member 1;
s3: forming a plurality of first connection point groups and a plurality of second connection point groups between the first sheet and the second sheet; wherein
Each first connecting point group comprises two first connecting points 21 which are oppositely arranged, a fixed area is formed between the two first connecting points 21, and the distance between the two first connecting points 21 is matched with the diameter of the elastic piece 1 in a stretching state so as to fix the elastic piece 1; preferably, the distance between the two first attachment points 21 is equal to or slightly less than the smallest diameter of the elastic element 1 at the maximum stretched length. In other words, the distance between the two first connection points 21 is determined by the static friction between the material of the first connection point 21 and the material of the elastic member 1 when the elastic member 1 is in any degree of stretching.
Each second connection point group comprises two oppositely arranged second connection points 22, a limiting area is formed between the two second connection points 22, the distance between the two second connection points 22 is larger than the diameter of the elastic element 1 in a normal state, so that the elastic element 1 can move in the limiting area to a certain extent along the vertical direction in the drawing, and the elastic element 1 is also allowed to stretch or contract in the horizontal direction in the drawing;
s4 a: in one or more selected areas 3 between at least two first groups of attachment points, the elastic element 1 is cut such that the elastic element 1 in the selected area 3 is in a relaxed state, such that the application of a logo, print, instructions or the like in the selected area or the printing of a logo, print, instructions or the like directly in the selected area is not collapsed by the elastic element 1.
Further, as a preferred embodiment, a plurality of elastic members 1 are included in parallel.
