Further, after step S2, the method may further include:
in step S21, hem 14 is fixed.
A pair of nip rollers having a slit is provided downstream after the formation of the hem 14, and the face sheet 11, the core sheet 12, and the bottom sheet 13 forming the hem 14 are passed through the slit so that the hem 14 is completely adhered to the face sheet 11, forming a fixed structure.
S3: a fixing device is arranged on the folded edge 14;
the fastening means is an adhesive layer 15. typically, the adhesive layer 15 is formed by spraying or spraying an adhesive on the flap 14, and the mask is fastened to the wearer's face, such as the face or the bridge of the nose, via the adhesive layer 15.
When the adhesive is in a fluid liquid state, it is preferably added to the surface of flange 14 by a spraying process, when the adhesive is in an emulsified semi-solid state, it is preferably added to the surface of flange 14 by a coating or doctor-blading process, and when the adhesive is in a viscous paste or solid state, it is preferably added to the surface of flange 14 by a doctor-blading process or a sizing process.
It will be understood that said adhesive layer 15 may have a predetermined shape on the flange 14, such as a strip, intermittent dots, continuous sheet, etc.
It will be appreciated that the spray head or coating device may be arranged in a fixed position to form the adhesive layer 15 on the flange 14 as the facing layer 11, core layer 12 and base layer 13 pass through the spray head or coating device as they are transported downstream by the idler rollers.
In one embodiment, the adhesive layer 15 is configured to include one or more adhesive units in the form of dots, lines or sheets, which are arranged at intervals.
Furthermore, the viscose units are arranged at equal intervals.
The size and the area of the viscose unit can be adjusted according to actual needs.
Further, step S3 may be followed by a step of providing a protective layer on the adhesive layer 15.
The protective layer has a separation surface with low surface tension, and it can be understood that the separation surface can be formed by adding a material with low surface tension on the surface of the sheet material, such as silicone oil, specifically, the protective layer can be release paper, release film, and the like.
S4: cutting the body 10 composed of the surface layer, the core layer and the bottom layer in a predetermined shape and separating the body 10.
The body 10 may be slit, for example, by a slitting knife, and the body 10 may be separated from the stack of the face layer 11, the core layer 12, and the bottom layer 13 by removing excess material. The preset shape can be the shape enclosed by the cutting knife.
It can be understood that, laminating the surface layer 11, the core layer 12 and the bottom layer 13 before slitting may be further included, so that the surface layer 11, the core layer 12 and the bottom layer 13 are combined into a whole and then slit, on one hand, the separated body 10 may be integrated, and on the other hand, the excess material recovery is also facilitated.
The lamination can be performed by a heat sealing method, such as a pair of bottom roller and heat sealing roller with slit, when the surface layer 11, the core layer 12 and the bottom layer 13 pass through the slit, the heat sealing roller and bottom roller perform heat sealing to the predetermined positions of the surface layer 11, the core layer 12 and the bottom layer 13, of course, in other embodiments, an adhesive can be disposed between the surface layer 11, the core layer 12 and the bottom layer 13, and the surface layer 11, the core layer 12 and the bottom layer 13 form an integral body by adhesion.
Further, when the mask includes a covering portion covering the mouth and nostrils of the mask wearer' S face and extending portions extending from both sides of the covering portion toward the ear sides of the face, respectively, the extending portion and the covering portion may be integrally formed or separately formed, it is understood that when the extending portion and the covering portion are integrally formed, the body 10 will be used as the covering portion and the extending portion, and when the extending portion and the covering portion are separately formed, the body 10 will be used as the extending portion, it is understood that a step of forming the covering portion is further included before step S4, and a step of coupling the covering portion with both the extending portions is further included after step S4.
More specifically, the partial extending part is overlapped with the covering part, and the overlapped area is combined, wherein the combination can be heat seal, ultrasonic bonding or gluing.
In addition, the main body 10 may also be used as a covering part, and when the main body 10 is used as a covering part, the adhesive layer 15 is used for attaching to the bridge of the nose of the wearer, and the method further includes a step of forming an extension part before step S4 and a step of bonding the covering part and the two extension parts after step S4.
Further, step S4 may be preceded by the step of performing a secondary fixing of flap 14 along the edge line of flap 14, said secondary fixing including heat sealing of flap 14 to face layer 11 along the edge line of flap 14.
As can be seen from the above description, in the manufacturing method, the existing step of performing intermittent processing one by one is not provided on the body 10, so that on one hand, the production efficiency is greatly improved, on the other hand, the mask can be completely attached to the face when being worn, the occurrence of air leakage is reduced, and meanwhile, no nose clip or ear loop is required, and the damage to the bridge of the nose or the ears is reduced.
Referring to fig. 4 and 5, the present invention also provides a mask manufactured according to the above steps, and the specific structure has been described in the above description, and is not repeated 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.
