The thin layer serves as a leakproof layer for guiding the flow and preventing back leaching of sanitary articles such as diapers and sanitary napkins. Referring to Fig. 1, a preferred embodiment of the method for forming a thin layer flow guiding structure of the present invention comprises the following steps: Step 11. Forming a plurality of holes in a thin layer. Referring to FIG. 2, in the embodiment, the ill: step is that the thin layer 2 is placed on a template provided with a plurality of perforations, and the method of adsorbing the holes by the negative or the way of breaking the holes by the water needle is formed in the thin layer 2. The plurality of holes 20 that correspond to the perforations. Step 2. Form a plurality of ribs raised relative to the first side surface on the first side of the thin layer. Referring to FIG. 3, the thin layer 2 has opposite first side 21' and first side 22, and in the present embodiment, the thin layer 2 is formed by placing the thin layer 2 formed with the broken hole 2 On the first molding die 3, the first-shaped 201225940 mold 3 has a molding die body 31 and a plurality of first ridges 32 raised by a first surface 301 of the first molding die body 31, and the first ridges 32 may be For example, a strip extending in the direction of the vertical view 3 is formed. The thin layer 2 is placed on the first surface 3〇1 of the first molding die body 31 with the second side surface 22 facing the first molding die 3, and the thin layer 2 is correspondingly adsorbed by vacuum suction. The region of a raised portion 32 corresponds to a plurality of ribs 23 (shown in FIG. 5) which are formed in a plurality of ridges. The first forming mold 3 may be placed in a flat plate for the thin layer 3 to be placed thereon for vacuum suction or in a cylindrical form (e.g., a cage structure) for the passage of the thin layer 3 in a rotational manner. Step 13: forming a plurality of recesses recessed relative to the first side surface on the first side of the thin layer. Referring to FIG. 4, the thin layer 2 of the step 12 is turned over, and the first side surface 21 faces the second molding die 4 and is placed on the second molding die 4, and the thin layer is adsorbed by vacuum suction. The first side surface 21 of the second surface 21 forms a plurality of recesses 24 recessed with respect to the first side surface 21, and more specifically, the second Chenglong 4 of the presently closed one has a second forming body, and a plurality of second forming mold bodies 41 The second surface 4 of the second surface 4 〇 隆 embossed and the plurality of recesses 43 recessed by the second molding die body 41 (four). When the thin layer 3 is placed on the second molding die 4, the ribs 23 which have been formed in the step 12 are respectively protruded into the depressed portions 43 of the second molding die 4, and the thin layer 3 The area corresponding to the second raised portion 42 is attached to the surface of the second raised portion 42 due to the force of negative pressure adsorption, so that the grooves 24 are formed on the first side surface 21, and the grooves 24 can also be regarded as thin The rib structure of the second side 22 of the layer 2 is raised. The second molding die 4 may be placed in a flat plate type for 201225940, on which the thin layer 3 is placed for vacuum suction or in a cylindrical form (e.g., a cage structure) for the passage of the thin layer 3 in a rotating manner. Referring to FIG. 5', it is worth mentioning that, in the present embodiment, the first side 21 of the thin layer 2 defines a plurality of grooved flow paths 25 due to the spacing of the ribs 2", when the fluid drops In addition to the surface tension of the fluid that can be destroyed by the ribs 23, the groove flow path 25 can also disperse the fluid flow from the concentration of the first side of the thin layer 3, thereby concentrating on a certain area. When the groove 24 is formed, the second surface tension of the fluid can be destroyed, so that the fluid becomes smaller and the bead flows into the groove 24 and passes through the thin layer 2 in the groove 24, of course. The perforations 20 distributed in the ribs 23 and the grooved channels 25 are also available for fluid to pass through. Referring to Figure 6, another aspect of the thin layer 2 formed by the present invention may be formed by the aforementioned steps. The same, the difference is only that the structure of the first ridge portion of the first molding die is changed, so that when the ribs 3 of the thin layer 2 are formed, the ridges extend in the s-shaped direction, and each rib 23 is along the same The partial section in the longitudinal direction is a recessed groove 231, and the structure of the groove 231 is also advantageous for guiding and destroying The surface tension of the body, and similarly applied to the structure of the second ridge portion of the second molding die, is such that the groove 24 of the thin layer 2 extends in a slight direction, and the groove 24 is along its length. The partial section is a raised island shape 241. In the above aspect, the first side surface 21 of the thin layer 2 is formed by forming the convex rib 23 and then forming the groove 24, but the order is not limited thereto, as shown in Fig. 7. The first molding die 6 used in another method may also be a first molding die body 61 and a first surface-surface 6 of the first molding die body 61 201225940 (the first recessed surface) The recessed portion 62, the thin layer 5 placed on the first surface 601 of the first molding die body 61 forms a recess 53 corresponding to the first recessed portion 62 on the first side by negative adsorption, and the recess 53 The second side 52 has a convex rib structure. Next, the thin layer 5 is turned over, and the second molding die 7 is used to form the rib 54. The second molding die 7 includes a second molding die body 71, and a plurality of a second recessed portion 72 of the second molding die body 71 recessed by the second surface 7〇1 and a plurality of second tables of the second molding die body 71 The ridge portion 73 of the ridge 1 is formed by the groove 53 formed by the first molding die 6 correspondingly covering the ridge portion 73 of the second molding die body 71 when the thin layer member 5 is placed on the second molding die 7. The upper portion of the thin layer 5 corresponding to the second recess portion 72 forms a convex rib which is raised by the first side surface 51. In the foregoing embodiment, the thin layer 2 The 2, 5, and 5 holes, the ribs 23, 54 and the grooves 24, 53 are respectively formed by different molding dies, but in other variations: the state: by changing the dies 2 The structure of the 5, or the portion 6 of the second molding die 3, 6 may also be such that the hole 20 is formed simultaneously with the ribs 23, 54 or with the grooves 24, 53. In addition, the ribs 23, 54 and the grooves m of the thin layers 2, 2', and 5 may be formed by the molding die 4, 7 in a second form. Referring to FIG. 9', a second preferred embodiment of the present invention is Compared with the foregoing embodiment, the second preferred embodiment utilizes a press roll forming, and the ribs and grooves of the thin layer are simultaneously formed. Wherein, the roller 81 is formed with a plurality of first-tooth teeth 8U and a plurality of first tooth grooves 812. The U-wheel 82 is formed with a plurality of first-tooth slots 821 for the first-tooth-shaped teeth 811 to extend into 201225940 and a plurality of The second convex teeth 822' of one of the slots 812' can be driven to roll in opposite directions, so that the first protruding teeth 811 of one of them protrude into the second slot 821 of the other roller 82. Further, the second convex tooth 822 of the winding wheel 82 also extends into the first gingival portion of the roller 81. The thin layer 9 is driven to pass between the two rollers 81, 82, and although the thin layer 9 passes through two Between the rollers 81, 82, the portion of the thin layer 9 corresponding to the roller 82 of the flute 82 is formed by the first protruding tooth 811 being pushed into the second slot 821 to form a rib 92, a thin layer The object 9 corresponds to the first tooth groove 812 and the second tooth 822 is pushed into the first tooth groove 812 to form a groove 93' recessed with respect to the first side surface 91. The action of step 13 can be completed at one time. According to the above, the present invention has the structure of the ribs 23, 54 and the grooves 24, 53 by the forming method, and the flow guiding grooves can also be formed between the ribs 23 and 54 to make the thin The layers 2, 5 have a better flow guiding effect, so that the object of the present invention can be achieved. However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
