Description

  The present invention relates to a peeling tape for peeling off a release liner attached to the surface of a double-sided tape from the double-sided tape and a method for applying the same.

  Conventionally, it is known to attach exterior parts (base materials) such as a door garnish and a protector to a vehicle door body or the like using a double-sided tape. Then, when attaching these base materials to the vehicle body, a double-sided tape is previously attached to the base material, and when attaching the base material, a release liner (exfoliation) attached to the surface of the double-sided tape is attached. In many cases, an operator directly peels paper (also called release paper).

  However, since it is not easy to remove the release liner from the surface of the double-sided tape by hand, there is a problem that it takes time to remove the release liner and the work efficiency of the substrate mounting operation is deteriorated.

  In order to solve such a problem, for example, as shown in FIG. 2 of Patent Document 1, a peeling tape is attached to the surface of a release paper (release liner), and the release tape is picked up from the release tape. Can be peeled off from the surface of the double-sided tape. Thus, in Patent Document 1, the double-sided tape is attached not only to the original mounting surface but also to a separately provided holding adhesive surface, thereby increasing the adhesive area between the double-sided tape and the molding (base material). Even if the peeling tape is picked up and the release paper is peeled off, it is said that the double-sided tape itself can be prevented from being peeled off together with the release liner.

Japanese Patent No. 2989111

  By the way, when peeling a release liner from the surface of a double-sided tape using a peeling tape, there are the following problems.

  That is, as shown in FIG. 4 and FIG. 8 of the above-mentioned Patent Document 1, when a peeling tape is applied at a right angle to the direction of peeling the release liner (release paper) (longitudinal direction of the release liner), the release liner is removed. There is a possibility that the force to peel off concentrates on the side edge of the double-sided tape, and the double-sided tape itself tends to peel off from the substrate.

  On the other hand, when the roll-shaped double-sided tape is cut and attached to the substrate, the adhesive surface of the double-sided tape 109 may protrude from both ends of the release liner 119 as shown in FIG. In this way, with the adhesive surface of the double-sided tape 109 protruding beyond the release liner 119, as shown in FIG. 2 of Patent Document 1, the peeling tape 101 is attached to the end portion 119b of the release liner 119. As shown in FIG. 13B, there is a possibility that the adhesive surface of the peeling tape 101 and the adhesive surface of the double-sided tape 109 may come into contact with part A. Then, after a certain amount of time has passed, the adhesive surface of the peeling tape 101 and the adhesive surface of the double-sided tape 109 are strongly bonded. Therefore, when the substrate is attached, the peeling tape 101 is picked and the release liner is picked up. When it is going to peel off 119, there exists a problem that double-sided tape 109 itself peels from a base material.

  The present invention has been made in view of such points, and the object of the present invention is to remove the release liner from the double-sided tape with a simple structure while suppressing the double-sided tape from peeling off from the base material in the peeling tape. It is to provide a technology for peeling.

  1st invention is a tape for peeling for peeling off the release liner currently affixed on the surface of the double-sided tape affixed on the base material from the said double-sided tape, Comprising: From the said double-sided tape on the adhesive surface side And the adhesive surface of the first tape so as to cover a substantially strip-shaped first tape coated with an adhesive having excellent adhesiveness to the release liner and a part of the first tape in the longitudinal direction. A substantially strip-shaped second tape that is superposed on the surface and whose non-adhesive surface is easily peelable from the surface of the double-sided tape, and at least one longitudinal end of the first tape is the second tape Projecting on one side in the longitudinal direction from one end in the longitudinal direction of the second tape, the adhesive surface side at the end on the one side in the longitudinal direction of the second tape, or the end on the one side of the second tape of the first tape In the part corresponding to the part On the adhesive surface side, a peeling portion capable of easily peeling the first tape and the second tape is formed, and the end portion of the release liner is connected to one side in the longitudinal direction of the second tape. The end of one side in the longitudinal direction of the first tape is attached to the surface of the release liner so as to be sandwiched between the end of the first tape and the first tape.

  In a second aspect based on the first aspect, the peeling portion is formed on the adhesive surface side at the end portion on one side in the longitudinal direction of the second tape, and is less likely to bend than the first tape. When the peeling part corresponding part corresponding to the peeling part in the first tape is warped, the peeling part is separated from the peeling part corresponding part, while when the peeling part corresponding part is extended substantially straight, the peeling part and It is comprised so that the said peeling part corresponding | compatible part may approach.

  A third invention is characterized in that, in the first or second invention, the other end in the longitudinal direction of the first tape substantially coincides with the other end in the longitudinal direction of the second tape. .

  According to a fourth invention, in the first or second invention, the other end in the longitudinal direction of the first tape protrudes to the other side in the longitudinal direction from the other end in the longitudinal direction of the second tape. Is.

  According to a fifth invention, in any one of the first to fourth inventions, the peeling portion is a member that can be easily peeled off from the adhesive surface of the first tape, on one side in the longitudinal direction of the second tape. It is formed by affixing on the adhesive surface in the edge part of this.

  In a sixth aspect based on any one of the first to fourth aspects, the peeling portion bends an end portion on one side in the longitudinal direction of the second tape so that the adhesive surfaces of the second tape are bonded to each other. It is formed by pasting.

  In a seventh invention according to any one of the first to fourth inventions, the peeling portion is a portion where no adhesive is applied to the adhesive surface side at the end on one side in the longitudinal direction of the second tape. It is characterized by being formed.

  According to an eighth invention, in any one of the first to seventh inventions, the first tape is formed to be transparent or translucent, while the peeling portion is a color different from the color of the first tape. It is characterized by being formed.

  The ninth invention is a method of applying a peeling tape for peeling the release liner attached to the surface of the double-sided tape attached to the base material from the double-sided tape, Adhesive surface overlaps the adhesive surface of the first tape so as to cover a part of the first tape in the longitudinal direction of the first tape coated with an adhesive having excellent adhesiveness with the release liner. And a strip-shaped second tape whose non-adhesive surface can be easily peeled off from the surface of the double-sided tape, wherein at least one longitudinal end of the first tape is one longitudinal direction of the second tape. A peeling tape that protrudes to one side in the longitudinal direction from the end and has a peeling portion that can be easily peeled from the first tape on the adhesive surface side at the end on the one side in the longitudinal direction of the second tape. Prepare A step of affixing one end of the first tape to the surface of the release liner so that one end of the second tape overlaps the other end of the release liner; Lifting the other end of the peeling tape so as to warp the peeling portion corresponding to the peeling portion of the tape, and peeling the peeling portion from the first tape; and Lowering the other end and attaching the peelable part corresponding part to the surface of the release liner, and extending the peeled part corresponding part to the other side of the peeling tape so as to extend substantially straight. Lifting and peeling the other end of the release liner from the double-sided tape, and sandwiching the end of the release liner between one end of the second tape in the longitudinal direction and the first tape; , It is characterized in that comprises.

  According to the first invention, the peeling tape has a structure that is easy to handle because the first and second tapes are overlapped and integrated. Moreover, a peeling part is formed in the adhesive surface in the edge part of the longitudinal direction one side of a 2nd tape or the adhesive surface in the site | part corresponding to the edge part of the 1st side of the 1st tape of the 1st tape. Therefore, the end portion of the release liner can be easily sandwiched between the end portion on one side in the longitudinal direction of the second tape and the first tape.

  Furthermore, since one end in the longitudinal direction on the adhesive surface side of the first tape protrudes to one side in the longitudinal direction rather than one end in the longitudinal direction of the second tape, the peeling tape is easily attached to the surface of the release liner. be able to. In addition, when the end portion of the release liner is sandwiched between the end portion on the one side in the longitudinal direction of the second tape and the first tape, the adhesive surface of the first or second tape on which the release portion is not formed It will inevitably stick to the end of the liner.

  In this way, the peeling tape has the end portion of the release liner sandwiched between the end portion on one side in the longitudinal direction of the second tape and the first tape (in other words, the adhesive surface of the first tape is Since the second tape to be covered is sandwiched between the release liner and the double-sided tape), the adhesive surface of the first tape and the adhesive surface of the double-sided tape are reliably in contact with each other. Can be suppressed.

  Then, when the other end of the peeling tape is lifted, an adhesive having better adhesion to the release liner than the double-sided tape is applied to the first tape, and the non-adhesiveness of the second tape Combined with the fact that the surface can be easily peeled off from the surface of the double-sided tape, the release liner can be easily peeled off from the surface of the double-sided tape.

  As described above, the release liner can be peeled off from the double-sided tape with a simple structure without peeling off the double-sided tape from the substrate.

  According to the second invention, when the peeling tape is applied to the release liner, for example, the surface of the release liner so that the end on one side of the second tape overlaps the end on the other side of the release liner. If the end on one side of the first tape is affixed to the tape and the other end of the peeling tape is lifted so that the corresponding portion of the peeling portion is warped from that state, the peeling portion can be easily removed from the first tape. Can be peeled off.

  Then, after affixing the peeling part corresponding part to the surface of the release liner, this time, if the other end of the peeling tape is lifted so that the peeling part corresponding part extends substantially straight, the release liner It is possible to peel the end of the other side from the double-sided tape and to sandwich it between the peeled portion and the peeled portion corresponding portion.

  As described above, the end portion of the release liner can be easily sandwiched between the end portion on one side in the longitudinal direction of the second tape and the first tape.

  According to the third invention, the first and second tapes do not stick to the operator's hand even if the operator grasps the end of the other side in the longitudinal direction of the peeling tape. Workability at the time of peeling from the surface is improved.

  According to the fourth invention, for example, when a plurality of double-sided tapes are separated from each other and are attached to the base material in a substantially linear shape, the end of the other side of the release liner in one of the adjacent double-sided tapes And affixing one end of the first tape in the longitudinal direction and affixing the other end of the first tape in the longitudinal direction to the end of one side of the release liner of the other adjacent double-sided tape. It becomes possible. Thereby, if the release liner of the other double-sided tape is peeled from the other side toward the one side, the release liner of one double-sided tape can also be peeled off. Therefore, it is possible to peel the release liner from a plurality of double-sided tapes at once, so that the working efficiency can be greatly improved.

  According to 5th invention, a peeling part can be easily formed by using the member which can be easily peeled from the adhesive surface of a 1st tape, such as a release paper, for example. In particular, in the second invention, it is possible to make the peeled portion easier to bend than the first tape without using a second tape having a different thickness or material from the first tape.

  According to the sixth aspect of the present invention, the peeling portion can be easily formed simply by bending the second tape and attaching the adhesive surfaces to each other. In particular, in the second invention, the second tape can be made easier to bend than the first tape by increasing the thickness of the peeling portion without using a second tape having a different thickness, material, or the like.

  According to the seventh invention, for example, it is not necessary to use a release paper or bend the second tape, so that the peeling tape can be more easily manufactured.

  According to the eighth invention, when the peeling tape is attached to the release liner, the first tape which is always on the near side with respect to the operator is made transparent or translucent, and the peeling portion is made the color of the first tape. By using different colors, the position of the peeling portion can be easily recognized. Therefore, the workability at the time of attaching the peeling tape to the release liner is improved.

  According to the ninth invention, the peeling liner is peeled off from the state in which one end of the first tape is attached to the surface of the release liner without performing the complicated operation of manually peeling the release liner from the surface of the double-sided tape. The other end of the tape is lifted once (the peeling part is peeled off from the peeling part corresponding part), lowered (the peeling part corresponding part is attached to the peeling liner), and lifted again (the peeling liner is peeled off from the peeling part and the peeling part) The peeling tape can be attached to the end portion of the release liner by a simple operation of sandwiching between the corresponding portions. Therefore, the workability at the time of sticking the peeling tape on the release liner can be further improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in FIGS. 1-12, in order to make a figure legible, the thickness of a film, an adhesive layer, etc. is exaggerated and shown. Furthermore, the side surfaces of the film and the like are hatched even if they are not cross-sectioned for easy identification. In the following description, the end on one side in the longitudinal direction is simply referred to as “one side end”, and the end on the other side in the longitudinal direction is simply referred to as “other side end”.

(Embodiment 1)
FIG. 1 is a view showing a door garnish to which a picking tape according to this embodiment is attached. The door garnish (base material) 29 is attached to the stepped portion 29b of the wall portion 29a extending in the longitudinal direction and the long double-sided tape 9 which is separated from each other and attached in a substantially straight line. It is attached to the door body of the vehicle (not shown) by the six short double-sided tapes 9. In addition, the double-sided tape 9 uses what applied the adhesive to both surfaces of the acrylic foam.

  The door garnish 29 is shipped with these double-sided tapes 9 attached in advance, and each double-sided tape 9 is provided with a double-sided tape 9 in order to prevent the adhesiveness of the double-sided tapes 9 from being reduced or sticking to unintended items. A liner tape (release liner) 19 using a polyethylene film is attached to the surface (adhesive surface) of the tape 9.

  The picking tape (peeling tape) 1 attached to the liner tape 19 is used to peel the liner tape 19 from the double-sided tape 9. In addition, the code | symbol 11 in FIG. 1 has shown the joint tape mentioned later. Moreover, in FIG. 1, in order to make a figure legible, the adhesive layer and the release paper 7 mentioned later are abbreviate | omitting illustration.

  As shown in FIG. 2, the picking tape 1 includes a picking film tape (hereinafter referred to as PF tape) 3, a tacking film tape (hereinafter referred to as TF tape) 5, and a release paper (peelable member) 7. ing.

  The PF tape (first tape) 3 includes a transparent or translucent substantially strip-like polyethylene film 13 and a polyethylene-based adhesive 23 applied thereto. Thus, since the adhesive surface of the PF tape 3 is composed of the polyethylene-based adhesive layer 23, it is easy to become familiar with the same polyethylene liner tape 19. Excellent adhesiveness.

  The TF tape (second tape) 5 includes a substantially strip-like polyethylene film 15 that is transparent or translucent as the polyethylene film 13, and a polyethylene adhesive 25 applied thereto. Specifically, the other end in the longitudinal direction of the PF tape 3 substantially coincides with the other end in the longitudinal direction of the TF tape 5 so as to cover a part of the PF tape 3 in the longitudinal direction. The adhesive surface of the PF tape 3 is superimposed on the adhesive surface of the PF tape 3 so that one end in the longitudinal direction of the PF tape 3 protrudes to one side in the longitudinal direction from one end in the longitudinal direction of the TF tape 5.

  Thus, the picking tape 1 has a structure that is easy to handle because the PF tape 3 and the TF tape 5 are overlapped and integrated. Further, at the other end 1a of the picking tape 1, the PF tape 3 and the TF tape 5 cover each other's adhesive surface, so that even if the operator grasps the other end 1a of the picking tape 1, the PF The tape 3 and the TF tape 5 do not stick to the operator's hand. Furthermore, since one end in the longitudinal direction on the adhesive surface side of the PF tape 3 protrudes to one side in the longitudinal direction from one end in the longitudinal direction of the TF tape 5, the picking tape 1 can be easily attached to the surface of the liner tape 19. Can be attached. Since the TF tape 5 is made of polyethylene like the liner tape 19, its non-adhesive surface can be easily peeled off from the adhesive surface of the double-sided tape 9.

  On the adhesive surface side of the one end portion 5b of the TF tape 5, a peeling portion 5a capable of easily peeling the PF tape 3 and the TF tape 5 is formed. Specifically, a release portion 5 a is formed by attaching release paper 7 that can be easily peeled off from the adhesive surface of the PF tape 3 to one end portion 5 b of the TF tape 5. Since the release paper 7 uses a color different from the color of the PF tape 3 formed to be transparent or translucent, the position of the peeling portion 5a can be easily recognized even from the PF tape 3 side. be able to.

  Thus, since the peeling part 5a is formed in the one side edge part 5b of the TF tape 5, as shown to Fig.3 (a), let the other side edge part 19b of the liner tape 19 be TF tape 5 Can be easily sandwiched between the one end portion 5b and the PF tape 3. Then, the other end 19b of the liner tape 19 is sandwiched between the one end 5b of the TF tape 5 and the PF tape 3 so that the one end 3b of the PF tape 3 is When affixed to the surface, the peeling part corresponding part 3a corresponding to the peeling part 5a in the PF tape 3 will inevitably stick to the other end 19b of the liner tape 19 (part A in FIG. 3A). reference).

  In addition, when the other end 19b of the liner tape 19 is sandwiched between the TF tape 5 and the PF tape 3, the non-adhesive surface of the TF tape 5 that can be easily peeled off from the adhesive surface of the double-sided tape 9 becomes a double-sided tape. 9, the contact between the adhesive surface of the PF tape 3 and the adhesive surface of the double-sided tape 9 is suppressed (see part B in FIG. 3A).

  Therefore, if the other end 1a of the picking tape 1 is grasped and pulled so as to be raised from the other side in the longitudinal direction toward one side (in the direction of the white arrow) as shown in FIG. The liner tape 19 can be easily peeled off from the surface of the double-sided tape 9 without peeling off the double-sided tape 9 from the door garnish 29.

  Here, the peeling portion 5 a is formed by sticking the release paper 7 to the TF tape 5, so that it is more difficult to bend than the PF tape 3 made of the same material as the TF tape 5. For this reason, when the peeling tape corresponding to the peeling portion corresponding portion 3a is separated from the peeling portion corresponding portion 3a, the picking tape 1 is separated from the peeling portion corresponding portion 3a. 3a approaches.

  Thus, the operator can remove the other end 19b of the liner tape 19 from the double-sided tape 9 by hand and sandwich it between the peeling part 5a and the peeling part corresponding part 3a, for example, FIG. As shown to (a), the one side edge part 5b of TF tape 5 is piled up on the other side edge part 19b of the liner tape 19, and as shown in FIG.4 (b), the peeling part corresponding | compatible part 3a is warped from this state. Accordingly, it is possible to take the method of peeling the peeling portion 5a from the PF tape 3 and sandwiching the other end 19b of the liner tape 19 between the peeling portion 5a and the peeling portion corresponding portion 3a. In FIG. 4, the pressure-sensitive adhesive layer is not shown for easy understanding of the drawing.

  Next, an example of the manufacturing method of the picking tape 1 is demonstrated using FIG. In FIG. 5, the pressure-sensitive adhesive layer is not shown for easy understanding of the drawing.

  First, as shown in FIG. 5A, a wide PF tape 3 is affixed to a mount 39 that can be easily peeled off from the polyethylene adhesive 23.

  Next, as shown in FIG. 5 (b), the end portion of the PF tape 3 is peeled off from the mount 39 to expose more than half of the adhesive surface. Then, the adhesive surface of the TF tape 5 on which the wide release paper 7 is attached so as to cover approximately half of the adhesive surface is attached to the exposed adhesive surface of the PF tape 3.

  Next, the posture of the PF tape 3 is returned to the same state as that shown in FIG. 5A so that the TF tape 5 and the release paper 7 are sandwiched between the PF tape 3 and the mount 39, and then the state shown in FIG. As shown, the PF tape 3, TF tape 5 and release paper 7 are cut to approximately the same width as the double-sided tape 9. Thus, the picking tape 1 can be manufactured by a simple method.

-Paste method-
Next, an example of a method for attaching the picking tape 1 to the liner tape 19 will be described with reference to FIGS.

  First, as shown in FIG. 6A, the one end portion 5b of the TF tape 5 overlaps the other end portion 19b of the liner tape 19, in other words, the peeling portion 5a of the liner tape 19 is seen in a plan view. The one end 3b of the PF tape 3 is attached to the surface of the liner tape 19 so as to overlap the other end 19b. At this time, when the picking tape 1 is affixed to the end of the liner tape 19 in the direction perpendicular to the longitudinal direction, the force for peeling the liner tape 19 is concentrated on the side edge of the double-sided tape 9, and the double-sided tape 9 is removed from the door garnish 29. There is a risk of peeling off. For this reason, it is desirable to arrange the picking tape 1 at the center in the direction perpendicular to the longitudinal direction of the liner tape 19 as shown in FIG.

  Next, as shown in FIG. 6B, the other end 1 a of the picking tape 1 is lifted in the direction of the white arrow, and the TF tape 5 is rolled up from the surface of the liner tape 19. Then, as shown in FIG. 6C, the other end 1a of the picking tape 1 is further lifted in the direction of the white arrow to open the direction of the black arrow so as to warp the peeling portion corresponding portion 3a. Thus, the peeling part 5a is peeled from the PF tape 3.

  Next, as shown in FIG. 7 (a), the other end 1a of the picking tape 1 is lowered in the direction of the white arrow and a finger or the like is pressed in the direction of the hatched arrow so that the peeling portion corresponding portion 3a is the liner tape. Affixed firmly to the other end 19b of 19. At this time, there is a possibility that the peeling portion corresponding portion 3a and the adhesive surface of the double-sided tape 9 may contact each other, but since the contact is only instantaneous, the peeling portion corresponding portion 3a and the adhesive surface of the double-sided tape 9 are strong. It is not glued.

  Next, as shown in FIG. 7 (b), the other end 1 a of the picking tape 1 is lifted again in the direction of the white arrow, and the other end 19 b of the liner tape 19 is peeled off from the double-sided tape 9. Then, as shown in FIG. 7C, the other end 1a of the picking tape 1 is further lifted so as to extend the peeling portion corresponding portion 3a substantially straight, and the other end 19b of the liner tape 19 is lifted. Is peeled off from the double-sided tape 9 and the peeling portion 5a is closed in the direction of the black arrow.

  As a result, as shown in FIG. 8A, the TF tape 5 extends substantially straight, and the other end 19 b of the liner tape 19 is connected to the one end 5 b (peeling portion 5 a) of the TF tape 5 and the PF tape. 3 (peeling part corresponding part 3a), as shown in FIG. 8 (b), the other end part 1a of the picking tape 1 is lowered in the direction of the white arrow. Thus, the attachment of the picking tape 1 to the liner tape 19 is completed.

-Effect-
According to the present embodiment, since the peeling portion 5 a is formed on the adhesive surface of the one side end portion 5 b of the TF tape 5, the other side end portion 19 b of the liner tape 19 is connected to the one side end of the TF tape 5. It can be easily sandwiched between the portion 5b and the PF tape 3.

  Thus, the picking tape 1 is in a state where the other end 19b of the liner tape 19 is sandwiched between the one end 5b of the TF tape 5 and the PF tape 3, in other words, the adhesive of the PF tape 3. Since the TF tape 5 covering the surface is attached to the liner tape 19 with the liner tape 19 and the double-sided tape 9 being sandwiched, the adhesive surface of the PF tape 3 and the adhesive surface of the double-sided tape 9 are in contact with each other. Can be surely suppressed.

  Then, when the other end 1a of the picking tape 1 is lifted, the PF tape 3 is more excellent in adhesion to the liner tape 19 than the double-sided tape 9, and the non-adhesive surface of the TF tape 5 is The liner tape 19 can be easily peeled from the surface of the double-sided tape 9 due to the fact that it can be easily peeled off from the surface of the double-sided tape 9.

  As described above, the liner tape 19 can be peeled from the double-sided tape 9 with a simple structure without peeling the double-sided tape 9 from the door garnish 29.

  Further, when the picking tape 1 is affixed to the liner tape 19, the PF tape 3 that is always on the near side with respect to the operator is made transparent or translucent, and the release paper 7 having a color different from the color of the PF tape 3 is used. By using it, the position of the peeling part 5a can be easily recognized. Therefore, workability when the picking tape 1 is attached to the liner tape 19 is improved.

  In addition, from the state where the one end portion 3b of the PF tape 3 is attached to the other end portion 19b of the liner tape 19 without performing the complicated work of manually peeling the liner tape 19 from the surface of the double-sided tape 9. The other end 1a of the picking tape 1 is once lifted (the peeling part 5a is peeled from the peeling part corresponding part 3a), lowered (the peeling part corresponding part 3a is attached to the liner tape 19), and lifted again (liner tape 19). The picking tape 1 can be attached to the other end 19b of the liner tape 19 by a simple operation of sandwiching the tape between the peeling portion 5a and the peeling portion corresponding portion 3a. Therefore, the workability at the time of sticking the picking tape 1 to the liner tape 19 can be further improved.

(Modification 1)
The first modification is different from the first embodiment in the configuration of the peeling portion 5a. Hereinafter, differences from the first embodiment will be described with reference to FIG.

  In this modification, without using the release paper 7, as shown in FIG. 9, the one end portion 5 b of the TF tape 5 is bent and the adhesive surfaces of the TF tape 5 are attached to each other, thereby separating the peeling portion. 5a is formed. Thereby, the peeling part 5a can be easily formed only by bend | folding the TF tape 5 and sticking the adhesive surfaces. Moreover, the peeling part 5a can be easily thickened and made harder to bend than the PF tape 3 without using a TF tape 5 having a different thickness or material from the PF tape 3.

  Furthermore, if the color of the polyethylene film 15 of the TF tape 5 is different from the color of the polyethylene film 13 of the PF tape 3, the position of the peeling portion 5a can be easily recognized.

(Modification 2)
Modification 2 differs from Embodiment 1 and Modification 1 in the configuration of the peeling portion 5a. Hereinafter, differences from Embodiment 1 and Modification 1 will be described with reference to FIG.

  In this modification, the peeling part 5a is formed by providing the site | part which does not apply | coat the adhesive 25 to the adhesion surface in the one side edge part 5b of the TF tape 5, as shown in FIG. In other words, in this modification, the peeled portion 5a is formed by using the TF tape 5 in which the polyethylene film 15 is only half coated with the polyethylene adhesive 25 (on the other side in the longitudinal direction from the center). Has been. The TF tape 5 to which only half of the polyethylene-based pressure-sensitive adhesive 25 is applied is, for example, such that the pressure-sensitive adhesive 25 easily adheres to a portion of the surface of the polyethylene film 15 where the pressure-sensitive adhesive 25 is to be applied. While the activation treatment is performed as usual, the portion where the application of the adhesive 25 is not planned can be easily formed by not performing the activation treatment.

  Thereby, when manufacturing the picking tape 1, since it is not necessary to use the release paper 7 or bend | fold the TF tape 5, the picking tape 1 can be manufactured still more easily.

  In addition, it is possible to make the peeling part 5a more difficult to bend than the PF tape 3 by using the polyethylene film 15 thicker than the polyethylene film 13. If the color of the polyethylene film 15 of the TF tape 5 is different from the color of the polyethylene film 13 of the PF tape 3, the position of the peeling portion 5a can be easily recognized.

(Embodiment 2)
This embodiment is different from the first embodiment in that the joint film tape 33 is used as the first tape. Hereinafter, differences from the first embodiment will be described with reference to FIGS. 1, 11, and 12.

Then, as shown in FIG. 11, the other end in the longitudinal direction of the JF tape 33 is TF so that the joint tape 11 can be applied across the liner tape 19 that is separated from each other and arranged in a substantially straight line. The tape 5 protrudes from the other end in the longitudinal direction to the other side in the longitudinal direction. The joint tape 11 has the same structure as the picking tape 1 except that the JF tape 33 protrudes to the other side in the longitudinal direction from the TF tape 5, and thus the same method as the manufacturing method described in the first embodiment. In addition, it can be affixed to the other end 19b of the liner tape 19 in the same manner as the affixing method described in the first embodiment.

  When the liner tape 19 is peeled off from the plurality of double-sided tapes 9 that are separated from each other and arranged in a substantially straight line by using the joint tape 11, as shown in FIG. 12 (a), the double-sided tape 9 at the left end of the drawing is used. While the picking tape 1 is affixed to the other end 19b of the liner tape 19, the other end 11a of the joint tape 11 is affixed to the one end 19a of the liner tape 19, and the second from the left in the figure. The other end 33b of the joint tape 11 is affixed to the other end 19b of the liner tape 19 of the double-sided tape 9. At this time, the other end 19b of the liner tape 19 is sandwiched between the JF tape 33 (peeling part corresponding part 33a) and the release paper 7 (peeling part 5a).

  Then, if the other end 1a of the picking tape 1 is grasped and pulled so as to be raised from the other side in the longitudinal direction to the one side as shown in FIG. The plurality of liner tapes 19 can be peeled from the surface of the double-sided tape 9 at a stretch without being peeled off from the garnish 29.

  When the joint tape 11 is affixed to the one end 19a of the liner tape 19, the adhesive surface of the JF tape 33 and the adhesive surface of the double-sided tape 9 are in contact with each other at the portion A in FIG. However, when the joint tape 11 is peeled from the other side in the longitudinal direction to the one side, no force acts in the direction of peeling the double-sided tape 9 from the door garnish 29. It does not peel off from the door garnish 29 itself.

-Effect-
According to the present embodiment, for example, when a plurality of double-sided tapes 9 are attached to the door garnish 29 so as to be separated from each other in a substantially straight line, the other side of the liner tape 19 in one of the adjacent double-sided tapes 9 The one end portion 33b of the JF tape 33 is attached to the end portion 19b, and the other end portion 11a of the JF tape 33 is attached to the one end portion 19a of the liner tape 19 of the other adjacent double-sided tape 9. It becomes possible to attach. Thereby, if the liner tape 19 of the other double-sided tape 9 is peeled from one side to the other side, the liner tape 19 of the one double-sided tape 9 can also be peeled off. Accordingly, the liner tape 19 can be peeled off from the plurality of double-sided tapes 9 at a stretch, and the working efficiency can be greatly improved.
