Description

Adhesive tape for artificial nails, and artificial nails having the same {ADHESION TAPE OF ARTIFICIAL NAIL AND ARTIFICIAL NAIL HAVING THE SAME}

The present invention relates to an adhesive tape for artificial nails, and to artificial nails having the same. More specifically, the present invention relates to an adhesive tape for artificial nails for producing an artificial nail with an adhesive or adhesive tape, and an artificial nail having the same.

Artificial nails are currently available in a wide variety of shapes and patterns, and a variety of methods for attaching them to natural nails are also disclosed. In order to fix artificial nails to natural nails, i) a method of using instantaneous adhesive, ii) a method of using double-sided tape, i) a method of using free glue and the like are used.

According to the method of using the instant adhesive, after applying a predetermined amount of the instant adhesive on the back surface of the artificial nail or the upper surface of the natural nail, the artificial nail is applied by pressing on the natural nail. Instant adhesives have the advantage of being easy to use. Natural nails can be damaged by their toxic ingredients and they are used on a limited basis because of their disadvantages of inadequate detachment.

Preglue is used in a similar way to the instant adhesive, and has the advantages of being neutral pH, non-toxic, and set clear. However, preglue is relatively expensive compared to instant adhesives and is also of limited use.

Compared to the above-mentioned instant adhesive or preglu, double-sided tape has less damage to natural nails, is easy to use, and the unit price is relatively low, so that technology development and use thereof are steadily increasing. Hereinafter, a double-sided tape for artificial nails disclosed in the related art will be described with reference to the drawings.

1 is a schematic cross-sectional view for explaining a conventional double-sided tape for artificial nails, Figure 2 is a schematic cross-sectional view for explaining an artificial nail with a double-sided tape for artificial nails shown in FIG.

1 and 2, the double-sided tape 10 for artificial nails has a shape corresponding to the artificial nail body 20 as a whole, and the adhesive film 13 and the release paper 15 on the release film 11. Are arranged sequentially. In this case, the adhesive film 13 has an adhesive component on both sides, and one surface of the adhesive film 13 is attached to the back 21 of the artificial nail body 20, and the other surface of the adhesive film 13 is a natural nail. (Not shown). That is, the adhesive film 13 plays a role of fixing the artificial nail body 20 to natural nails (not shown).

In order to attach the double-faced tape 10 for artificial nails to the artificial nail body 20, first, the release paper 15 is separated from the adhesive film 13 to expose one surface of the adhesive film 13. The double-sided tape 10 is pressed against the artificial nail body 20 so that the exposed one surface contacts the back surface of the artificial nail body 20. As a result, the artificial nail 30 is manufactured.

Subsequently, when the release film 11 is separated from the artificial nail 30, the other surface of the adhesive film 13 is exposed. After arranging the artificial nail 30 on the natural nail, and pressing the artificial nail 30 so that the other surface of the adhesive film 13 is in contact with the upper surface of the natural nail, the artificial nail by the adhesive force of the adhesive film 13 30 is attached to the natural nails.

The artificial nail 30 is shipped in a state before the release film 11 is separated from the adhesive film 13. The consumer separates the release film 11 from the adhesive film 13 immediately before using the artificial nail 30. When the artificial nails are shipped with the release film 11 separated, the adhesive film 13 may be contaminated or the adhesive component of the adhesive film 13 may be volatilized during movement or storage. To prevent this, the artificial nail 30 is shipped without the release film 11 being separated.

However, in the conventional artificial nail 30 to which the double-sided tape 10 is attached, an accident in which the release film 11 is naturally separated during movement or storage often occurs. In more detail, the artificial nail body 20 is formed to be bent as a whole, and the back surface of the artificial nail body 20 also has a predetermined radius of curvature. When the double-sided tape 10 from which the release paper 15 is separated is attached to the rear surface of the artificial nail body 20, the double-sided tape 10 has the same radius of curvature as the rear surface of the artificial nail body 20. In this case, the double-sided tape 10 generates a restoring force to restore the original state, that is, the state where the radius of curvature is '0'.

In general, the restoring force is relatively small compared to the adhesive force between the adhesive film 13 and the artificial nail 30. Thus, the adhesive film 13 does not naturally separate from the artificial nail 30. However, the adhesive force between the adhesive film 13 and the release film 11 is almost similar to the restoring force so that the release film 11 is naturally separated from the adhesive film 13 when a predetermined time elapses. .

The reason why the release film 11 is naturally separated from the adhesive film 13 is due to other factors besides the restoring force. As an example, the difference in thermal expansion coefficient can be mentioned. In general, since the artificial nail body 20 and the double-sided tape 10 are made of different materials, they have different coefficients of thermal expansion. Also in the double-sided tape 10, the thermal expansion coefficients of the adhesive film 13 and the release paper 15 on the release film 11 are different.

When the artificial nail 30 is shipped and transported to another region or stored in another place for a long time, the artificial nail 30 may be exposed to a surrounding environment at various temperatures. Since the adhesive film 13 is generally excellent in elasticity and one surface is attached to the back surface of the artificial nail body 20, the adhesive film 13 is substantially the same as the artificial nail body 20. However, since the release film 11 is relatively inferior in elasticity and its adhesion with the adhesive film 13 is not so large, it is deformed differently from the adhesive film 13 or the artificial nail body 20. This often causes a problem that the release film 11 is naturally separated from the adhesive film 13.

When the release film 11 is naturally separated from the artificial nail 30, the other surface of the adhesive film 13 is exposed, and foreign matters are adhered to the other surface, or the adhesive component of the adhesive film 13 volatilizes. Caused. Therefore, not only the adhesive performance of the artificial nail 30 is lowered, but also a serious economic / time loss such as return / exchange of the artificial nail 30 is caused.

The present invention has been made to solve the problems of the prior art as described above, one object of the present invention is to provide an adhesive tape for artificial nails that can effectively maintain the adhesive performance.

Another object of the present invention is to provide an artificial nail that can effectively maintain the adhesive performance by using the adhesive tape.

In order to achieve the above object of the present invention, the artificial nail according to an embodiment of the present invention, the artificial nail body formed with the back bent, the adhesive sheet attached on the back, and the adhesive along the back It is flexibly attached on the sheet and an incision is formed to halve the restoring force. In this case, the incision may be formed crosswise at the center of the release film, or may be formed to extend in a dotted line from one end of the release film, or may be formed to extend in a straight line from one end of the release film. Also, the incision may extend from one end to the other end of the adhesive portion.

Adhesive tape for artificial nails according to another embodiment of the present invention, the first sheet, the adhesive sheet and the second sheet is made by sequentially stacking, as the adhesive sheet is attached to the curved back of the artificial nail body is deformed 1 Incision is formed in the first sheet to prevent the sheet from being separated from the adhesive sheet. In this case, a break line may be formed in the first sheet, the adhesive sheet, and the second sheet so as to correspond to the edge of the artificial nail body in order to partition and separate the adhesive portion of the area corresponding to the back surface of the artificial nail body. A plurality of break lines may be formed in parallel across the first sheet, the adhesive sheet, and the second sheet in order to partition the plurality of adhesive parts, and in this case, sections for preventing the adhesive parts from interfering with each other on both sides of each break line. Curves are formed over the first sheet, the adhesive sheet and the second sheet.

According to the present invention, as the adhesive sheet is deformed by forming an incision in the adhesive tape for artificial nails, the first sheet can be prevented from being naturally separated from the adhesive sheet. In addition, by forming a bent line on both sides of the break line, it is possible to quickly and accurately attach the adhesive tape for artificial nails to the body of the artificial nail even in the mass production of artificial nails using a jig. Finally, it is possible to efficiently and efficiently manufacture artificial nails with good performance.

Hereinafter, an adhesive tape for artificial nails and artificial nails according to preferred embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited or limited by the following embodiments.

Figure 3 shows a rear view for explaining the adhesive tape for artificial nails according to the first embodiment of the present invention, Figure 4 is a plan view of the adhesive tape for artificial nails shown in Figure 3, Figure 5 4 is an enlarged cross-sectional view of the adhesive tape for artificial nail shown in FIG.

3 to 5, in the adhesive tape 100 for the artificial nail, the adhesive film 120 is disposed on the release film 130, and the release paper 110 is disposed on the adhesive film 120.

The adhesive film 120 is a member having substantially the same function as a general double-sided tape, and the release film 130 and the release paper 110 are attached to upper and lower surfaces of the adhesive film 120, respectively.

The adhesive film 120 may be made of an inorganic material, a nonwoven fabric, an acrylic foam, or the like. Among these, the adhesive film 120 is preferably made of acrylic foam having a firm adhesive strength and a transparent material.

The release film 130 and the release paper 110 are members coated on only one surface so that they can be easily detached from the adhesive film 120, and the adhesive film 120 is contaminated or the adhesive component volatilizes from the adhesive film 120. It is used to prevent things.

The release film 130 and the release paper 110 have a difference in transparency, flexibility, and the like, but perform substantially the same function. Accordingly, unlike the illustrated example, the release films 130 or the release sheets 110 may be disposed on both upper and lower surfaces of the adhesive film 120.

The adhesive tape 100 for the artificial nail has a break line 101 formed to correspond to the edge of the artificial nail body (not shown). The break line 101 is used to partition and separate the adhesive portion 105 of the area corresponding to the artificial nail body.

As shown in the adhesive tape 100 for artificial nails, break lines 101 of various sizes are formed, and the adhesive portions 105 corresponding to the artificial nail bodies of various sizes are attached to one artificial nail adhesive tape. It is preferable to form in (100). In this case, the adhesive part 105 corresponding to the artificial nail bodies of a specific size can be easily selected. However, the adhesive tape 100 for artificial nails may be manufactured to correspond to the artificial nail body of a specific size without forming a break line 101 on the artificial adhesive tape 100.

When one adhesive part 105 is selected and pressed downward or upward from the artificial nail adhesive tape 100 having various sizes of adhesive parts 105 formed, the selected adhesive parts 105 are cut along the break line 101. . The adhesive part 105 cut out from the entire adhesive nail adhesive tape 100 has a release paper 111, an adhesive film 121, and a release film 131 having an area corresponding to the rear surface of the artificial nail body.

As already described above, one surface of the release paper 111 and the release film 131 is coated, so that the adhesive force between the adhesive film 121 and the release paper 111, and the adhesive film 121 and the release film 131 The adhesive force between) is relatively small. Therefore, the release paper 111 and the release film 131 can be separated relatively easily from the adhesive film 121.

As the adhesive film 121 is deformed in the release film 131, an incision line 109 is formed to prevent the release film 131 from being naturally separated from the adhesive film 121.

The incision line 109 is formed by finely digging a groove in the release film 131. The incision line 109 becomes a starting point at which the release film 131 can be cut to both sides, and is formed upward from the lower end 135 of the release film 131. In this case, the incision 109 preferably does not extend to the upper end 136 of the release film 131. This is to prevent the release film 131 from being completely bisected on both sides. Alternatively, a plurality of incisions 109 may be formed in parallel with the lower end 135 of the release film 131.

The incision line 109 allows the release film 131 to be cut as the adhesive film 121 is deformed, thereby preventing the release film 131 from being naturally separated from the adhesive film 121. Hereinafter, the cut line 109 will be described in detail.

The incision line 109 is formed in a vertical direction from the lower end 135 of the release film 131. When the adhesive film 121 is deformed, for example, when the adhesive film 121 extends to both sides, the release film 131 is cut to both sides based on the cut line 109. This is due to the principle that the release film 131 is deformed along the adhesive film 121 by the adhesive force between the release film 131 and the adhesive film 121.

In general, the release film 131 has a smaller elasticity than the adhesive film 121. Therefore, the restoring force generated in the deformed release film 131 is greater than the restoring force generated in the deformed adhesive film 121. When the adhesive part 105 is deformed, frictional force is generated between the adhesive film 121 and the release film 131 due to the difference in the restoring force. The friction force lowers the adhesive force between the release film 131 and the adhesive film 121, and as a result, the release film 131 may be separated from the adhesive film 121.

However, in the adhesive portion 105 of the adhesive tape 100 for the artificial nail according to the present embodiment, when the adhesive film 121 is deformed, the release film 131 is cut, and the restoring force is generated in the release film 131. do. If the restoring force of the release film 131 can be reduced, the release film 131 can be prevented from being naturally separated from the adhesive film 121.

Deformation factors of the adhesive film 121 are various. For example, when the adhesive film 121 is attached to the back of the arch nail body, the adhesive film 121 is deformed and attached in the same manner as the shape of the back of the artificial nail body. Naturally, the release film 131 attached to the other surface of the adhesive film 121 is also deformed in the same manner as the adhesive film 121.

As another example, the adhesive film 121 may be deformed by heat. The adhesive film 121 has an inherent thermal expansion coefficient, and in general, the thermal expansion coefficient of the adhesive film 121 is different from the thermal expansion coefficients of the release paper 111 and the release film 131. Therefore, the release paper 111, the adhesive film 121, and the release film 111 are thermally deformed differently according to the temperature of the surrounding environment where the adhesive part 105 is exposed.

As described above, when the adhesive film 121 is deformed, the release film 131 is based on the incision line 109 in the adhesive portion 105 of the adhesive tape 100 for the artificial nail according to the present embodiment. Are nutrients. Therefore, the release film 131 may be prevented from being naturally separated from the adhesive film 121. In the present embodiment, the release paper 111 is first separated from the adhesive portion 105, and thus the cut line 109 is not formed on the release paper 111, but the cut line 109 is also formed on the release paper 111 in some cases. can do.

6 to 9 are perspective views for sequentially explaining a method for manufacturing artificial nails by attaching the adhesive portion shown in Figure 2 to the artificial nail body.

2 to 9, the adhesive part 105 is selected from the adhesive tape 100 for artificial nails having various sizes of adhesive parts 105 and pressed downward or upward to separate the selected adhesive parts 105. . In this case, the adhesive portion 105 is relatively easily cut along the break line 101.

The release paper 111 is separated from the separated adhesive part 105 to expose one surface of the adhesive film 121.

The artificial nail 155 is manufactured by pressing the adhesive part 105 against the artificial nail body 150 so that the exposed one surface of the adhesive film 121 is in contact with the rear surface 151 of the artificial nail body 150. The back surface 151 of the artificial nail body 150 is formed to be curved in an arcuate shape, and the adhesive part 105 is also deformed to be curved along the back surface 151 of the artificial nail body 150. In this case, the adhesive film 121 is directly attached to the back surface 151 of the artificial nail body 150, and has stretchability, so that the restoring force generated in the adhesive film 121 is relatively small. However, the release film 131 is relatively extensible and opens to both sides with respect to the incision line 109. As a result, the restoring force generated also in the adhesive film 121 is greatly reduced.

As described above, the artificial nail 155 is preferably released with the adhesive part 105 attached to the artificial nail body 150. In order to attach the artificial nail 155 to the natural nail (not shown), the release film 131 is separated from the adhesive film 121 to expose the other surface of the adhesive film 121. In this case, since the release film 131 is not fully bisected, the release film 131 can be separated at a time.

Thereafter, when the artificial nail 155 is pressed so that the other surface of the adhesive film 121 contacts the upper surface of the natural nail, the artificial nail 155 is attached to the natural nail.

Unlike the present embodiment as described above, the incision line 109 may be variously formed on the release paper 111. Hereinafter, the adhesive tape for artificial nails according to other embodiments of the present invention will be described with reference to FIGS. 10 to 13.

10 is a rear view illustrating the adhesive tape for artificial nails according to the second embodiment of the present invention, and FIG. 11 is an enlarged cross-sectional view of the adhesive tape for artificial nails shown in FIG. 10.

10 and 11, except for the artificial adhesive tape 100 and the release film 131 of the artificial nail adhesive tape 200 according to the first embodiment. same. Therefore, duplicate descriptions as possible will be omitted, but will be readily understood by those skilled in the art.

One adhesive part 205 is selected from the adhesive tape 200 for artificial nails in which adhesive parts 205 of various sizes are formed and pressed downward or upward. The selected adhesive part 205 is cut along the break line 201 to prepare a release paper 211, an adhesive film 221, and a release film 231 having an area corresponding to the back surface of the artificial nail body.

As the adhesive film 221 is deformed in the release film 231, a cut line 209 is formed crosswise to prevent the separation of the release film 231 from the adhesive film 221.

The incision line 209 is formed by finely grooved crosswise in the center of the release film 231. The incision line 209 is a starting point at which the release film 231 may be cut up, down, left, and right.

When the adhesive film 221 is attached to the main body of the artificial nail or deformed by heat, the release film 231 is cut up, down, left, and right based on the incision line 209. Therefore, the release film 231 does not naturally separate from the adhesive film 221.

The method of attaching the adhesive portion 205 in the artificial nail adhesive tape 200 according to the present embodiment to the artificial nail body (not shown) is substantially the same as in the first embodiment. However, when the release paper 211 is separated to attach the exposed adhesive part 205 of the adhesive film 221 to the back surface of the artificial nail body, the release film 231 is different in that it crosses open.

12 is a rear view illustrating the adhesive tape for artificial nails according to the third embodiment of the present invention, and FIG. 13 is an enlarged cross-sectional view of the adhesive tape for artificial nails shown in FIG. 12.

12 and 13, the artificial adhesive nail tape 300 according to the present embodiment is substantially except for the artificial adhesive tape 100 and the release film 131 according to the first embodiment. same. Therefore, duplicate descriptions as possible will be omitted, but will be readily understood by those skilled in the art.

One adhesive part 305 is selected from the adhesive tape 300 for artificial nails on which adhesive parts 305 of various sizes are formed and are pressed downward or upward. The selected adhesive part 305 is cut along the break line 301 to prepare a release paper 311, an adhesive film 321, and a release film 331 having an area corresponding to the back surface of the artificial nail body.

As the adhesive film 321 is deformed in the release film 331, a cut line 309 is formed in a cross shape in order to prevent the release film 331 from being naturally separated from the adhesive film 321.

The incision 309 is formed by digging a groove in a fine dotted line on the release film 331. The incision line 309 is a starting point at which the release film 331 may be cut to both sides, and is formed upward from the lower end 335 of the release film 331. In this case, the incision 309 may extend to the upper end 336 of the release film 331.

When the adhesive film 321 is attached to the body of the artificial nail or deformed by heat, and the like, the release film 331 is cut on both sides based on the incision line 309. Therefore, the release film 331 is not naturally separated from the adhesive film 321.

In general, the deformation amount of the adhesive film 321 is not so large, and the deformation amount of the release film 331 is not so large. Therefore, even when the cut line 309 is formed up to the upper end 336 of the release film 331, the release film 331 is not completely bisected by the deformation of the adhesive film 321.

The method of attaching the adhesive portion 305 in the adhesive tape 300 for artificial nails according to the present embodiment to the artificial nail body (not shown) is substantially the same as in the first embodiment. Therefore, duplicate description is omitted, but will be readily understood by those skilled in the art.

FIG. 14 is a rear view for explaining an adhesive tape for artificial nails according to a fourth embodiment of the present invention, and FIG. 15 is an enlarged cross-sectional view of the adhesive tape for artificial nails shown in FIG.

14 and 15, the adhesive tape 400 for artificial nails according to the present embodiment is for rapidly mass production of artificial nails, and the adhesive film 420 and the release paper on the release film 430 ( 410 is arranged in sequence. The materials of the release paper 410, the adhesive film 420, and the release film 430 are substantially the same as those of the first embodiment, and overlapping description thereof will be omitted.

In the adhesive tape 400 for artificial nails, a plurality of break lines 401 are formed to correspond to edges of artificial nail bodies (not shown) of various sizes, respectively. The break lines 401 may be formed on the release paper 410, the adhesive film 420, and the release film 430 so as to partition and separate the adhesive portions 405 having areas corresponding to the rear surfaces of the artificial nail bodies of various sizes. Formed over. In addition, the adhesive parts 405 are formed side by side in the horizontal direction from the lower end 402 of the adhesive tape 400 for artificial nails.

In the release film 431 of each adhesive portion 405, as the adhesive film 421 is deformed, an incision 409 is formed to prevent the release film 431 from being naturally separated from the adhesive film 421. The incision 409 may be formed in various ways as in the first to third embodiments.

Between both sides of the adhesive parts 405, that is, between the break lines 401, a bend line 460 is formed to apply free deformation to each adhesive part 405. The bending line 460 is formed by finely digging the release paper 410, the adhesive film 420, and the release film 430. The bend line 460 is preferably continuously formed to have a rhombus or triangle shape from the lower end 435 to the upper end 436 of the adhesive tape 400 for artificial nails. Detailed description of the bending line 460 will be described below in the method of attaching the adhesive portions 405 to the artificial nail bodies in the adhesive tape 400 for artificial nails according to the present embodiment.

FIG. 16 is a perspective view illustrating a jig in which an adhesive tape for artificial nails is disposed in FIG. 14, and FIG. 17 is a perspective view illustrating an artificial nail body set disposed on a jig illustrated in FIG. 16, and FIG. 18. Is a perspective view showing a press for pressing the artificial nail body set shown in FIG. 17 to the jig shown in FIG. 16, and FIG. 19 is a schematic perspective view for explaining a method for manufacturing artificial nails.

14 to 16, in order to mass produce a plurality of artificial nails, an adhesive tape 400 for artificial nails is disposed on a jig 470.

The jig 470 has a rectangular plate shape as a whole, and the molds 473 corresponding to the artificial nail bodies 450 are convexly formed from the top surface thereof. The molds 473 are formed to have an arch shape so as to correspond to the rear surfaces of the artificial nail bodies 450, respectively. Concave portions 474 are formed concavely on both sides of the molds 473.

The molds 473 preferably do not protrude from the top surface of the jig 470. To this end, both sides of each mold 473 are engraved to form molds 473 that do not protrude from the top surface of the jig 470.

The molds 473 are formed side by side in the horizontal direction. More preferably, the molds 473 are formed symmetrically with respect to the horizontal center line 475 of the jig 470. That is, a pair of molds 473 having the same shape are formed side by side in the horizontal direction. Hereinafter, the left side of the center line 475 is called the first mold part 471 and the right side is called the second mold part 472.

In order to mass produce artificial nails, first, adhesive tapes 400 for artificial nails are disposed on the first and second mold parts 471 and 472, respectively. In this case, the release paper 411 is preferably separated from each adhesive portion 405 of the adhesive tapes 400 for artificial nails and then disposed.

When arranging the artificial adhesive tapes 400, the lower ends of the artificial adhesive tapes 400 are disposed to be adjacent to the centerline 475 of the jig 470. As a result, a corresponding adhesive portion 405 is placed on each mold 473. This is because the molds 471 of the jig 470 are manufactured to correspond to the positions of the adhesive portions 405 in the adhesive tape 400 for artificial nails, respectively.

In further development, coupling protrusions 477 are formed on both sides of the upper surface of the jig 470 for easy placement on the adhesive tape 400 for the artificial nail on the first and second mold portions 471, respectively, The coupling holes 408 are formed at both sides of the adhesive tape 400 for artificial nails to correspond to the fields 477. When the adhesive tape 400 for the artificial nail is placed on the jig 470 so that the coupling holes 408 are respectively inserted into the coupling protrusions 477, the corresponding adhesive portion 405 is accurately positioned on each mold 473. Done.

Subsequently, the artificial nail body set 452 is disposed on the adhesive tapes 400 for the artificial nail, respectively. The artificial nail body set 452 is configured such that artificial nail bodies 450 corresponding to the molds 473 of the jig 470 are arranged side by side with respect to the connection bar 453. Naturally, the artificial nail body set 452 also corresponds to an artificial nail adhesive tape 400 disposed on the first and second mold portions 471 and 472, respectively.

An adhesive part 405 on which the adhesive film 420 is exposed is positioned under each artificial nail body 450. In more detail, the adhesive film 420 of the adhesion part 405 adjoins the back surface of each artificial nail main body 450.

Next, the artificial nail body sets 452 are pressed downward using the press 480. Press 480 is a device for pressing the artificial nail body set 452 so that the adhesive film 420 is firmly attached to the back of each artificial nail body 450, has a semi-cylindrical shape as a whole and the size of the jig 470 It is formed to correspond to. In this case, the press 480 includes a press portion 481 made of a cushioning material in order to prevent damage to the artificial nail body set 452 and to perform an efficient attachment process. The press unit 481 is preferably made of a material such as rubber, silicone, plastic, or synthetic resin.

The press 480 is positioned on an artificial nail body set 452 disposed on the jig 470 of the mold 473. In this case, the press 480 is disposed to coincide with the center of the jig 470.

Thereafter, the press 480 is rotated to the left and right to alternately press the artificial nail body sets 452 downward.

As the press 480 presses the artificial nail body set 452, the adhesive tape 400 for each artificial nail disposed on the first and second mold portions 471 is pressed downward as a whole. As a result, each adhesive portion 405 in the entire adhesive nail adhesive tape 400 is deformed to correspond to the shape of the mold 473 disposed below, and the margins 406 between each adhesive portion 405 are jig-shaped. It is inserted into the intaglio portions 474 of 470. That is, the adhesive tape 400 for artificial nails is deformed unevenly as a whole. As a result, the adhesive portions 405 are firmly attached to the back surfaces of the artificial nail bodies 450, respectively.

When the margin part 406 is inserted into the intaglio part 474, irregular tensile force is applied to the adhesive parts 405 positioned at both sides of the margin part 406. As a result, the positions of the adhesive parts 405 disposed on the molds 473 may be changed. If the adhesives 405 are incorrectly disposed on the molds 473, it is natural that the adhesives 405 are incorrectly attached to the artificial nail body 450. In order to prevent this, a bend line 460 is formed in the margin part 406 of the adhesive tape 400 for artificial nails according to the present embodiment.

The bend line 460 is the adhesive parts positioned at both sides of the margin part 406 by bending and partially cutting the margin part 406 to have a predetermined characteristic when the margin part 406 is inserted into the intaglio part 474. 405 prevents the occurrence of irregular tensile force. That is, the bend lines 460 prevent the bonds 405 from being incorrectly placed on the molds 473.

After the press 480 presses the artificial nail body set 452 and attaches the adhesive portion 405 to the artificial nail body 400, the press 480 connects the connection bar 453 of the artificial nail body set 452. In the pressing state), the margin part 406 of the adhesive tape 400 for artificial nails is pulled in the horizontal direction. As a result, the adhesive parts 405 are cut along the break lines 401 from the entire artificial nail adhesive tape 400, and the jig 470 restrains the adhesive tape 400 for the artificial nails except for the adhesive parts 405. ).

Thereafter, when the press 480 is separated from the artificial nail body set 452, and the artificial nail body set 452 is removed from the jig 470, a plurality of artificial nails arranged on both sides of the connecting bar 453 are manufactured.

According to the present invention, by forming an incision in the adhesive tape for artificial nails, it is possible to prevent the release film from being naturally separated from the adhesive film to contaminate the adhesive film or lower the adhesive force of the adhesive film. Thereby, the fall of the adhesive force of an artificial nail can be prevented. Furthermore, by forming a bent line on the adhesive tape for artificial nails, when the artificial nails are produced in large quantities, the adhesive tape for the artificial nails can be prevented from being incorrectly attached to the artificial nail body. Finally, artificial nails with excellent adhesion can be manufactured quickly and precisely.
