Therefore, the trace of the die cut formed on the release sheet 103 and the edge of the stamped label 101 are located at the same position.

[0003]

However, as shown in FIG. 11, the pressure-sensitive adhesive layer 105 formed on the back surface of the label.
Will flow into the die-cut traces 107 of the release sheet 103 and will adhere to the paper quality portion that is one layer below the release layer formed on the surface of the release sheet 103 and made of, for example, silicon. Therefore, when the label 101 is peeled from the release sheet 103 one by one and is automatically attached to an adherend, the label is attached to an automatic label attaching machine.
The label is not peeled in the normal direction from the release layer of the release sheet 103, and sometimes the label is wound on a take-up roll from the release plate in a state of being temporarily attached to the release sheet 103, or in an abnormal direction. It causes troubles such as peeling from the release sheet and sticking to the surface of the adherend.

Therefore, a main object of the present invention is to provide a novel label continuum capable of peeling a label from a release sheet in a normal direction and a method for producing the same.

[0005]

A first aspect of the present invention is to provide a release sheet with a die-cutting mark of a label formed in a direction intersecting with a traveling direction for peeling and a die-cut label. The die-cut mark of the label and the edge of the label are displaced in the direction intersecting the traveling direction so that the edges that intersect the traveling direction do not coincide with each other and are separated from each other. A label continuum that is temporarily attached to a release sheet with layers.

A second aspect of the present invention provides a release sheet,

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a perspective view of a label continuous body which is an embodiment of the present invention, and FIG. 2 is a sectional view of FIG. 1A-A. The label continuum 10 includes a release sheet 12, and a label 14 is temporarily attached to a release agent layer side main surface of the release sheet 12 with a pressure sensitive adhesive layer 16 on the back surface thereof. The release sheet 12 is formed by coating a release agent such as silicon on the surface of a long-sized base material to form a release layer. A die-cutting mark 18 is formed when the shape is die-cut. The position of the end edge 20a of the label 14 parallel to the transfer direction (arrow direction in FIG. 1) for peeling the label 14 and the end edge 20b of the label 14 formed in the direction orthogonal to the transfer direction are different. Position, in this embodiment, the label die cutting trace 18a parallel to the transfer direction at a position near the side edge of the release sheet 12 and the label die cutting orthogonal to the transfer direction at a position near the center of the label 14. Traces 18b are formed.
That is, the die-cut marks 18a and 18b of the label formed on the release sheet 12 in the advancing direction that advances for peeling and the direction orthogonal thereto, and the edge 20a that is orthogonal to the advancing direction of the die-cut label 14 and the advancing direction. 20
Label 1 so that it is separated from b without matching.
4 is temporarily attached to the release sheet 12.

Next, an embodiment of the method for manufacturing the label continuum 10 will be described below with reference to a typical manufacturing apparatus. First, a laminate is prepared by temporarily attaching a label base paper 22 which is a base of the label 14 to the main surface of the release layer 12 of the release sheet 12 with the adhesive layer 16, and the laminate is reeled 24.
It is formed so that it can be rolled up and sent to the label manufacturing process in sequence. The laminated body of the label base paper 22 and the release sheet 12 wound around the reel 24 is then sent to the step of die-cutting the label.

As a method of die-cutting the label, as shown in FIG. 3, a label die-cutting device 28, which is a means for die-cutting the label, is provided with a die roll 26 having an appropriate blade shape formed on the surface thereof. Send to. The label laminated body, which is die-cut into a predetermined shape by the label die-cutting device 28, is divided by the die-cutting groove 32 into the label 14 and the scrap 30 as shown in FIG. However, the die-cutting groove 32 formed by the label die-cutting device 28
Will dig deeper than the surface of the release layer of the release sheet 12 even with a precise label die-cutting device to form a label die-cut mark 18 as shown in FIG.

The laminated body punched into a predetermined shape by the label punching device 28 is next processed into the label base paper 2 described above.
2 and the release sheet 12, the adhesive layer 16 and the release sheet 1
It is sent to the label peeling re-temporary fixing device 34, which is a means for separating at the interface with 2. The label peeling / re-temporary attaching device 34 includes a peeling plate 36 which is a means for separating the pressure-sensitive adhesive layer 16 and the peeling sheet 12 at the interface thereof. By the release plate 36, the release sheet 12 sent in the horizontal transfer direction is suddenly folded back and pulled out in the opposite direction, so that the release sheet 12 and the label base paper 22 are separated from each other, and only the label base paper 22 is provided. It is constructed so that it can go straight according to its rigidity. Then, the peeling sheet 12 peeled by the peeling plate 36 is changed in direction by the conversion roll 38,
The release sheet 12 whose direction is changed by the conversion roll 38 is slightly shifted in the width direction of the release sheet 12 by the shift roll 39, and then pulled back to the original direction, as shown in FIG. It is temporarily attached to the surface of the adhesive layer 16 with the re-attachment plate 40.

The label 1 is placed in the width direction of the release sheet 12.
The length to be re-temporarily attached by shifting 4 is the length necessary for the label edge 20a parallel to the traveling direction of the label 14 and the label die cutting trace 18a parallel to the edge to be displaced and separated from each other. Samin Further, the length in which the label 14 and the peeling sheet 12 are peeled off by the label peeling / re-tempering device 34 is, for example, as shown in FIG. 4, the label die removal mark 18b and the width direction edge 20b of the label 14. The length is set to be necessary for the positions and to be displaced and separated.

As described above, by the action of the label peeling re-temporary fixing device 34, the edge 20a in the direction parallel to the advancing direction for peeling the stamped label 14 and the edge 20b in the direction direct thereto. Then, the label die-cut marks 18a and 18b formed on the release sheet 12 are re-temporarily attached without being aligned with the label die-cut marks 18b particularly in the width direction, that is, the label die-cut marks 18b in the width direction. Therefore, the distance between the peeling plate 36 and the re-temporary fixing plate 40 must be shorter than the length of the label 14 in the traveling direction. The laminated body on which the release sheet 12 and the label 14 are re-temporarily adhered in this way is rewound by the take-up reel 42 and wound up so as to be loaded into an automatic label sticking device (not shown).

In the present embodiment, the scrap 30 portion of the die-cut label base paper 22 has the pressing roller 44, and the label 14 is re-temporarily attached to the release sheet 12 in cooperation with the re-attachment plate 40. At the same time, the scraps 30 are taken off and taken up by the scraps removing reel 46, and only the necessary label 14 is re-temporarily attached to the release sheet 12.

However, this scrap removal may be performed by another method, for example, immediately after the label base paper 22 is die-cut into a predetermined shape by the label die-cutting device 28.

Further, the label peeling / re-temporary fixing device 34 described in the above embodiment continuously feeds the peeling sheet 12, the direction of the peeling sheet 12 is changed by the conversion roll 38, and the label 14 is re-temporarily fixed again. It is configured like
For example, as shown in FIG. 5, the release sheet 36 is separated from the label base paper 22 by the release plate 36, is temporarily wound around the take-up reel 48, and is then sent to the label 14 by the re-temporary attachment plate 40. 12 'may be separately prepared, loaded on the rewinding reel 50, and sent to the re-temporary attachment plate 40.

The label and the release sheet manufactured by the above-mentioned embodiments may have the following constitutions, for example. The label and the release sheet may have the following configurations, for example. The illustrated example of FIG. 7 is different from the illustrated example in that the label 50 has a flat circular shape, and the label 50 formed on the release sheet 52 in a direction intersecting the traveling direction (arrow in FIG. 6) for peeling is die-cut. Mark 54
The front arcuate portion 54a and the arcuate edge 50a of the label 50 that intersects the advancing direction of the die-cut label are separated from each other without coincidence. That is,
The label 50 is shifted in a direction intersecting the traveling direction, the die-cutting trace 54 is located, and the label 54 is temporarily attached to the release sheet 52.

The example shown in FIG. 8 is a modified example of the example shown in FIG. 7, and this label 60 is a plane ellipse and has an arcuate edge 60a of the label 60 which intersects the traveling direction of the die-cut label 60. , The arc-shaped label 6 formed on the release sheet 62
It is configured so as to be spaced apart from the die-cut marks 64 of 0 without matching. That is, the label 60 is shifted in a direction intersecting the traveling direction, and the front arcuate die-cut mark 64a is formed.
Is located. In particular, in the example shown in FIGS. 7 and 8, the front arcuate edges 50a and 60a of the labels 50 and 60 are displaced from the die-cut marks 54 and 64 only by shifting the label 50 in the direction intersecting the traveling direction. Since they are separated from each other, the intended purpose can be achieved.

In the example shown in FIG. 9, unlike the example shown in the figure, the label 70 is a plane triangle, and the die-cut mark 74 of the label 70 formed on the release sheet 72 is also formed in a plane triangle. Is temporarily attached in a direction that intersects the direction of travel. That is, the linear front end edge 70a of the label 70 that intersects at a right angle with the advancing direction for peeling the label 70 is perpendicular to the advancing direction for advancing for the peeling of the label 70 among the die-cut marks 74 of the label. It is configured so that it does not intersect with the intersecting linear portion 74a.

The example shown in FIG. 10 is different from the example shown in FIG. 1 so that the straight front end edges 80a of the label 80 intersecting the advancing direction for peeling the label 80 do not intersect at right angles, The label 80 is temporarily attached to the release sheet 82 while being displaced in a direction intersecting the traveling direction. That is, the front end portion 84a of the die-cutting trace 84 of the label 80 formed on the release sheet 82 that intersects the traveling direction does not coincide with the linear front end edge 80a of the label 80.
It is configured to be separated.
