Since the third mesh 321 of the molding die 3 has a smaller aperture than the first molding die. The aperture of 21, so that the coffee is "after the formation of the first perforation 61 is subjected to the suction of the second molding die 3. The device 52 is adsorbed, and each single first-hand J tooth hole 61 is not subject to the single king. A third mesh 3 21 absorbs six, τ $ 卜 ^ and force 盍 to cause or reduce the expansion or deformation of the first dental hole 61 ' at the same time 'the suction cylinder 200806456 in the drum % can also pass through the second mesh 321 And for the thin layer * 6 two first perforations ... : know to generate suction ' so that the thin layer 6 can still be adsorbed on the first layer 32 of the second 71 to allow the ribs 62 and depression The unevenness of the zone 1 can be smoothly absorbed and stretched. The third mesh 321 is mainly arranged to make the second molding. The air extracting device W in 3 can perform the adsorption stretching effect on the thin layer material 6 through the third and the eyepieces 321, and the hole cut in the third mesh is not limited to the aperture which must be smaller than the first mesh 2 . Then, the thin layer 6 is separated from the second molding die 3 and air-dried to the thin layer 6 + σ 〇 ° (perforated film, see FIG. 7), and is thin to contribute to the softening of the cold sputum. The layer 6 can be further disposed from the first to the bottom of the second molding die 3 by the internal blowing device (not shown) of the roller 3, by the external blowing force of the money device. Figure 4 'Re-(four)_ point indicates that the molding die 2, 3 is according to η, w, the younger one, she... the corresponding position, but the two molding dies 2., 3 = standing can also be adjusted according to the situation, for example When the second molding die 3 is drawn below the first molding die 2, the angle at which the thin layer is released from the J can be increased, and the thin layer 6 can be assisted to be detached from the first molding die 2. w $ mode The second second molding dies 2, 3 can also be arranged in a plane similar to the conveyor belt of 1 2: 5, the first molding die 2 is taken as an example, the first molding die 2 疋 ring, % laid on The two rollers 20, the outer circumference, the outer side, the second side of the steaming machine, and the outer side of the shovel, are placed on the top surface of the inner mold 2, and the two rollers 20 are driven to drive the first When the forming core 2 rotates, the thin layer is moved by the younger brother, and after passing through the air extracting device 51, or 12 200806456 (water needle device), the thin layer material 6 can be broken through the first mesh 21 to form a hole. The first perforation 61. - See Figure 7, Item 8'. Thus, the thin layer 6 formed by the above-mentioned molding method in combination with the mold has a plurality of first perforations 61 and a thin layer 6

The plurality of ribs 62 are formed by the plurality of first-perforations 61 defining the plurality of recessed regions 62 and surrounding each of the ribs 62 due to the formation of the auxiliary portions 62, and the plurality of first-perforations 61 are formed on the ribs 62. There are also partial dentitions. That is to say, the forming method of the present embodiment is to form the comprehensive first through-hole 61 in the thin layer 6 by the first inner wheel 2, and then on the thin layer 6 by the younger-forming die 3. The ribs 62 are formed by re-lifting, so that the ribs 62 are also distributed with the first perforations 6 ▲ as shown in FIG. 8 'When the thin layer 6 and the absorbing body 7 are combined to form the β-surgery 4 When the leakage preventing layer such as 4 塾 or diaper is treated, the thin layer 6 疋, the side on which the rib 62 is formed faces upward, and the absorbent body 7 is disposed on the 哕 layer 6 opposite to the rib 62 On one side, when the sanitary guard is used: (4) The side of the leak-absorbing H layer 6 is applied to the user's skin or wound 8 This day is only a thin layer due to the contact with the user's skin or wound 8 The top surface of the rib 62 is not distributed with the portion of the first through hole 61, so that the thin layer 4 can be further reduced to contact the skin or the wound 8 by the area of the rib 62. The contact or friction with the skin 8 causes the skin 8 to be sensitive or inflamed. Moreover, since the ribs 62 are also distributed on the ribs 62, the penetration effect is enhanced. The liquid guiding effect on the ribs q is reduced, and the liquid remaining between the thin layer 6 and the skin or the wound 8 is reduced, and the gas permeability of the thin layer 6 is improved, so that the skin is not easy to produce 13 200806456 It’s greasy and it’s easier to stay dry. Referring to FIG. 4 and FIG. 9, as mentioned in the foregoing description of the mold, the first and second molding dies 2, 3 can be arranged by the mesh to make the thin layer 6 into a stagnation/, and have a special pattern. Therefore, as shown in FIG. 9, the drum 2〇 can also be divided into a plurality of sections 2, 2, 2, 2, and 2, each of the sections 2, 2, 2, 2... a different molding die, so that a plurality of thin layers of different perforated patterns with different pattern patterns can be formed at one time.

When the thin layer mold is applied to a sanitary pad, it can be divided into different types such as a sputum type, a night type or an elongated type. Referring back to FIG. 4, a more specific point is that if one side of the thin layer 6 is defined as a bottom surface adjacent to the drum 20 30 and a side facing the water needle device 54 is a top surface, a thin layer is formed in the molding procedure indicated by =4. When the object 6 passes through the first molding die 2, the boring is caused by the suction force of the bottom surface thereof. At this time, the burr edge (not shown) is located on the bottom surface side, and similarly, when passing through the second molding die 3, It is also the force of suction on the bottom surface*, so the burrs are also located on the bottom side. The arrangement of the two molding dies 2, 3 is more conducive to maintaining the flatness of the top surface of the thin layer 6 for future use. As in the case of Fig. 9, the top side of the thin layer 6 which is in contact with the skin 8 is not caused to have a rough feeling due to the burrs. In summary, the present invention firstly forms the second perforation 61 of the second molding die 3 and the ribs after the first perforation 61 is formed in the thin layer 6 by the first mesh 2 of the first molding die 2. 312, and in the thin layer: forming a plurality of ribs 62 and recessed regions 62 such that the first through-holes 61 are distributed on the ribs 62 and in the concave (four) 621, especially in the thin layer for medical care.塾, feminine hygiene 塾 or baby diaper, - readable 14 200806456 The area of the ribs 62 actually in contact with the skin or wound, reducing the friction or discomfort caused by the contact of the thin layer 6 with the skin or wound 8 On the other hand, since a part of the first perforations 61 are distributed on the ribs 62, liquid can be prevented from staying on the ribs 62, which helps to make the contact between the ribs 62 and the skin or the wound 8 more dry, without causing The skin or wound 8 is irritated or allergic due to stickiness.
