Embodiments of the present invention will be described below in more detail with reference to the drawings. Figure 1
1A and 1B are diagrams illustrating an embodiment of a label and tack paper according to the present invention, wherein FIG. 1A is a plan view and FIG. 1B is a front view. Note that the same reference numerals are given to portions that perform the same functions as those of the above-described conventional example, and redundant description will be omitted as appropriate. The tack paper 10 includes a label 11 and a release paper 12. The label 11 is a part that is peeled off from the release paper 12 and adheres to an object to be adhered.
And an adhesive layer 11b. The label 11 has a cutout 11c formed by cutting one of the four corners. When peeling off the label 11, the label user hooks a notch on the notch 11c to make the peeling.

As the label substrate 11a, for example, paper such as high-quality paper, art paper, coated paper, synthetic paper, synthetic resin film, or a film-like substrate is suitably used. The pressure-sensitive adhesive layer 11b is a layer that enables the label base material 11a to be attached to an adherend, and includes an acrylic pressure-sensitive adhesive, a natural rubber-based pressure-sensitive adhesive,
It is formed by applying a synthetic rubber-based adhesive or a silicone rubber-based adhesive. The coating amount and coating thickness of the pressure-sensitive adhesive layer 11b are not particularly limited, but preferably the coating amount is 0.1 to 50 g / m ² and the coating thickness is 0.1 to 50 μm.
m.

The release paper 12 is a base material for protecting the pressure-sensitive adhesive layer 11b, and the upper surface thereof, that is, the surface on the side of the pressure-sensitive adhesive layer 11b is subjected to a release treatment with a silicone-based release agent or the like. The thickness of the release paper 12 is not particularly limited, but is usually 20 to 200 μm, preferably 40 to 100 μm.
m.

(First Manufacturing Method) FIG. 2 is a diagram showing a first manufacturing method of tack paper according to the present invention. Tack paper 10
Is manufactured as follows. The adhesive sheet 13 is supplied (adhesive sheet supply step # 101), and the label sheet 11 is separated from the release paper 12 by the separating member 21 (label separation step # 102). At this time, the adhesive is applied to the label sheet 1
1 stuck. Then, the label sheet 11 is punched by being sandwiched between the dies 22 and 23 to form a cutout portion 11c (a cutout portion forming step # 103).
2 (label re-attachment step # 104) and stock while folding (stock step # 105). The surfaces of the separating member 21 and the die 23 are coated with silicone to prevent the label sheet 11 from adhering.

According to this embodiment, the release paper 12 is once peeled off, punched out to form the notch 11c, and then bonded again, so that the notch 11c is discontinuous and the label Since only a part of the label 11a can be provided, a part to be discarded as garbage can be kept to a minimum and the entire label can be effectively used. For this reason, it is possible to reduce the manufacturing cost and prevent waste of resources. In addition, the notch 11c formed in this manner is a cause of peeling, so that the label 11 is easily peeled. In addition, the tack paper 10 can be manufactured using a commercially available pressure-sensitive adhesive sheet 13.

(Second Manufacturing Method) FIG. 3 is a view showing a second manufacturing method of tack paper according to the present invention. Tack paper 10
Is manufactured as follows. The label substrate 11a is supplied (label substrate supply step # 201), and an adhesive is applied to form an adhesive layer 11b (adhesive layer forming step # 20).
2) After punching by sandwiching between the dies 22 and 23 to form the notch 11c (notch forming step # 203),
The release paper 12 is attached (release paper attaching step # 204) and wound up (winding step # 205).

When the tack paper 10 shown in FIG. 1 is manufactured by a conventional manufacturing method, a release paper 12 coated with an adhesive on one side and a label base material 11a punched with a notch 11c are interleaved. Then, since it is manufactured, the adhesive is exposed from the cutout portion 11c. However, according to this manufacturing method, the adhesive is applied to the label base material 11a and then punched out to form the notch 11c. Therefore, the adhesive can be removed at the time of punching, and the adhesive can be removed.
No exposure from

(Third Manufacturing Method) FIG. 4 is a view showing a third manufacturing method of tack paper according to the present invention. Tack paper 10
Is manufactured as follows. The adhesive sheet 13 is supplied (adhesive sheet supply step # 301), and the label sheet 11 is separated from the release paper 12 by the separating member 21 (label separation step # 302). Then, printing is performed on a part of the label sheet 11 by the printing machine 24 to reduce the adhesive strength of the part (adhesive strength reducing step # 303), and the printed part is punched out by being sandwiched between the dies 22 and 23. The notch 11c is formed (a notch forming step # 304). In addition, by the adhesive force of the end surface of the adhesive layer 11b of the label sheet 11,
The punched pieces 11d may remain on the label sheet 11, but are blown off or sucked into a duct in a later step. Subsequently, the label sheet 11 is attached again to the release paper 12 (label reattachment step # 305),
After the punching pieces 11d remaining on the label sheet 11 are blown off by the air jet nozzle 25 (the blower process # 3)
06), and stock while folding (stock process # 307).

According to the manufacturing method of the present invention, the adhesive force of the punched piece 11d punched out when the notch 11c is formed is reduced in advance, so that the punched piece 11d remains on the label sheet 11. However, it does not adhere to the release paper 12. For this reason, the punched piece 11d can be easily blown off by the air jet nozzle 25, and the punched piece 11d can be reliably prevented from being mixed into the tack paper 10. In particular, if the adhesive strength reduction printing is performed with a color that is clearly different from the label body, the visual check is very easy.

(Modifications) Various modifications and changes are possible without being limited to the embodiment described above, and they are also within the equivalent scope of the present invention. For example, a plurality of labels may be formed on one piece of release paper. Further, in the third manufacturing method, the adhesive force is reduced by printing, but the same effect can be obtained by coating.

[0021]

As described above in detail, according to the first aspect of the present invention, the entire surface of the label can be effectively used because the notch is formed by cutting out a part.

According to the second aspect of the present invention, the notch portion is
Since one corner of the label substrate is formed by cutting, it is easy to manufacture.

According to the third aspect of the present invention, the label substrate comprises:
Since the size is substantially the same as the size of the release base material, it is possible to minimize the portion that is discarded as dust.

According to the fourth aspect of the present invention, the label attached to the release substrate is once separated from the release substrate and punched out to form a notch. Can be provided.

According to the fifth aspect of the present invention, a pressure-sensitive adhesive is applied to the label substrate to form a pressure-sensitive adhesive layer, and then punched out to form a notch. There is no exposure.

According to the sixth aspect of the present invention, the adhesive force of the punched piece punched in the notch forming step is reduced in advance, so that even if the punched piece remains, it can be surely removed. Can be removed.
