Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tab for temporarily fixing a terminal portion of a paper roll, which has been pretreated for splicing, to prevent unwinding.

[0002]

[Prior Art]

 Generally, in a rotary press, before the running paper fed out from the paper feed unit is exhausted, the ends of the paper rolls set in the paper feed unit are spliced so that the paper rolls are continuously fed out.

Therefore, the rolled paper is subjected to a pretreatment for splicing before or after being set in the paper feeding unit.

FIG. 7 shows a web L that has been subjected to pretreatment. The end a of the web L has a chevron shape, and an adhesive layer d is formed along the inclined edges b and c. Moreover, the apex of the chevron is prevented from being temporarily fastened and unwound by attaching the tab T ₀ .

Here, since the terminal portion a is pulled out together with the running paper by adhesion to the running paper, the tab T ₀ must be easily torn by pulling out the terminal portion a.

The tab T ₀ shown in FIG. 6 is conventionally known. The tab T ₀ is configured such that the pressure-sensitive adhesive layers 22 are formed on both ends of the front surface of the horizontally long portion 21 of the T-shaped support 20, and the pressure-sensitive adhesive layers 24 are provided on the back end of the vertically long portion 23.

[0007]

[Problems to be solved by the device]

By the way, in the conventional tab T ₀ , as shown in FIG. 7, the adhesive layer 22 of the horizontally long portion 21 is adhered to the inner surface of the web end portion a, and the back surface adhesive layer 24 of the vertically long portion 23 is formed. Since the terminal portion a is temporarily fixed by adhering it to the surface of the paper L, it is necessary to turn up the terminal portion a and insert the oblong portion 21 into the inside thereof, and it takes time and effort to attach the tab T ₀ , and There was a problem that it was difficult to automate.

Further, when the end portion is adhered to the running paper and pulled out, the tab T ₀ is torn from the corner portion 25 at the coupling position of the horizontally long portion 21 and the vertically long portion 23. A large pulling force is required, sometimes it is not torn, and there is a problem that reliability of temporary tacking is poor.

This invention solves the above-mentioned conventional problems, facilitates temporary fixing work of the terminal portion, and ensures that the temporary fixing is released when the terminal portion is connected to the running paper. It is a technical issue.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in this invention, a separating line is provided in the central portion of the supporting body with a required space between both ends of the supporting body and the side edges of the supporting body. An upper adhesive piece is used between the wire and the upper edge of the support, and a lower adhesive piece is used between the disconnection line and the lower edge of the support.Adhesive layers are formed on both the front and back surfaces of the upper adhesive piece. That is, a structure provided with an adhesive layer was adopted.

[0011]

[Action]

 In the tab having the above structure, the adhesive layer on the back side of the adhesive piece is adhered to the surface of the terminal portion formed in a chevron shape, and the adhesive layer on the back side of the lower adhesive piece is adhered to the surface of the paper roll. Temporarily stop.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, the support 1 is provided with a separating line 2, and a required space is provided between the separating line 2 and both sides of the supporting body 1. An upper adhesive piece 3 is provided between the separating line 2 and the upper edge of the support 1, while a lower connecting piece 4 is provided between the separating line 2 and the lower edge of the support 1.

Here, the shape of the upper adhesive piece 3 is arbitrary, and in the case of the embodiment, it is a trapezoid with tapered edges 5 formed on both sides. Adhesive layers 6 and 7 are provided on the front surface of the upper adhesive piece 3 on both front and back surfaces thereof with a predetermined distance from the separating line 2.

On the other hand, a pressure-sensitive adhesive layer 8 is provided on the rear surface of the lower adhesive piece 4 and on the front surface at a required distance from the separating line 2.

FIG. 3 shows a state in which the terminal portion a of the paper L is temporarily fixed by using the tab T ₁ having the above-described structure, and the back surface adhesive layer 7 of the upper adhesive piece 3 is formed in a mountain shape. The adhesive layer 8 on the rear surface of the lower adhesive piece 4 is adhered to the front surface of the paper L, while the adhesive layer 8 is adhered to the front surface of the front end portion of a.

By attaching the tab T _1, the terminal portion a is temporarily fixed and prevented from being unwound.

Here, an adhesive layer d for adhering to the running paper is provided on the surface of the terminal portion a along the oblique side of the terminal portion a, and the adhesive layer d and the surface adhesive layer of the upper adhesive piece 3 are provided. By pressing a part of the running paper to 6 and adhering it, a tensile force acts on the terminal portion a due to the movement of the running paper, and the tab T ₁ tears both ends of the disconnection line 2 by the tensile force, and the tab T ₁ is torn. The part a is fed out together with the running paper.

The tab T ₁ having the above structure protects the adhesive layers 6, 7 and 8 by attaching release paper to both the front and back surfaces of the support 1, or as shown in FIG. It is attached to a tape-shaped mount 10 that has been subjected to a mold release process, and the mount 10 is wound in a roll shape to protect the adhesive layers 6, 7, and 8. In the case of the roll-shaped tab tape T ₂ , it is preferable to add release paper to the surface of the tab T ₁ to protect the adhesive layer 6 on the surface.

[0019] In the tab tape T ₂ roll shown in FIG. 4, since the mount 10 by gel piece folding mount 10 steeper can be peeled off the tab T ₁ automatically away the tab T ₁ It is possible to automate the attachment of the tab T ₁ by adsorbing with a die-treated adsorption plate and pressing the adsorption plate onto the end portion a of the paper L.

In the embodiment shown in FIG. 1, the separation line 2 formed on the support 1 is shown as a straight cut line, but the present invention is not limited to this. For example, the separating line 2 may be a perforation, or may be a horizontally long hole as shown in FIG.

Further, the separation line 2 may be V-shaped as shown in FIGS. 5 (A) and 5 (D).

As shown in FIGS. 5 (c) and 5 (d), when the notches 11 are provided on both side edges of the support 1 so as to face both ends of the separation line 2, the tab T ₁ is more effective. Can be torn.

[0023]

[Effect of the device]

 As described above, in the tab according to the present invention, since it is possible to stick from the surface of the terminal portion of the paper roll, the temporary fixing work of the terminal portion is easy, and the tab sticking can be automated.

In addition, since the adhesive layer is also provided on the surface of the upper adhesive piece, the end portion of the winding paper can be more surely adhered to the running paper, and the end portion is brought into contact with the running paper. When the user wears the traveling paper and pulls the terminal portion by moving the traveling paper, both ends of the separation line are torn, so that the temporary fixing of the terminal portion can be reliably released.
