Description

[Detailed description of the invention] (Industrial application field) This invention relates to a pasting base material that has an adhesive layer on the back surface, and is used for, for example, stickers, labels, stamps, revenue stamps, envelopes, etc. The present invention relates to a suitable adhesion base material.

(Description of the Prior Art) Conventionally, this type of adhesive base material has been used, for example, as a sticker after being appropriately printed on its surface and processed into an appropriate size and shape.

Such seals are usually formed by arranging a large number of them vertically and horizontally through perforations for cutting in the vertical and horizontal directions. When such a sticker is to be pasted on a collection ledger, for example, the necessary sticker is cut off, the adhesive layer on the back side of the sticker is wetted with water, and the sticker is pasted.

However, before use, the adhesive layer formed on the back of such a seal dries and shrinks or acts on the base material, causing the grain of the base material that makes up the seal, that is, the paper. As a result, the entire seal is curved into a tiled surface shape as shown in FIG. 1 or a quilted surface shape as shown in FIG. Such curvature has the disadvantage of significantly reducing its commercial value. In addition, if a large number of such stickers are arranged and formed into a single relatively large sheet, the shape will look like a series of mountains as shown in Figure 3, and the above-mentioned problems will be even worse. It was becoming noticeable.

(Purpose of the invention) Therefore, the purpose of the invention is to provide a base material for adhesion that can maintain its commercial value without causing much curvature.

(Structure of the device) To put it simply, this device has an adhesive layer provided on the back side of the base material and a part of the base material in the thickness direction.
This is a base material for pasting in which cuts are formed to prevent the base material from curving.

The above objects and features of the present invention will become more apparent from the following detailed description with reference to the drawings.

(Description of Embodiment) FIG. 4 is a perspective view of a seal as an embodiment of this invention, FIG. 5 is a sectional view taken along line V-V in FIG. 4, and FIG. FIG. 3 is a back view of the seal shown in FIG.

The seal 1 includes a sheet-like base material 2 and an adhesive layer 3 formed on the back surface of the base material 2. A seal 1 is provided on the base material 2 by penetrating the adhesive layer 3 to prevent the seal 1 from curving. A cut 4 is formed. This sticker 1
is used as a service sticker, for example, and is pasted on a ledger, mount, etc. for collecting stickers.

The base material 2 is made of paper, synthetic resin, etc., for example.
The adhesive layer 3 is made of, for example, a starch-based adhesive such as dextrin, soybean paste, or a starch adhesive, or a water-soluble phenol-based adhesive. This adhesive layer 3 is activated by being wetted with water and generates adhesive force for sticking the sticker 1 to an object. In addition, these base material 2 and adhesive layer 3 have a lattice that intersects vertically and horizontally in a part of the thickness direction of adhesive layer 3 and base material 2, especially as shown in FIGS. 5 and 6. A cut 4 for preventing curvature is formed. This cut 4 causes the entire seal 1 to curve along the grain of the paper constituting the adhesive layer 3 and the base material 2 when the adhesive layer 3 dries and contracts or acts on the base material 2. This is to prevent this. That is, the cuts 4 work to give flexibility to the inner surface of the seal 1 that is about to shrink and counteract the shrinkage, so that the seal 1 as a whole can be prevented from curving. The cuts 4 may be formed into diagonally intersecting grid-like cuts 4a as shown in FIG. It is only necessary to form the label 1 in such a way that it can prevent the entire label 1 from being bent due to the effect of the cuts.

Incidentally, the interval between the cuts 4 can be changed depending on the use of the base material 2, but is, for example, about 0.5 to 1 mm.

Further, on the surface of the base material 2, as shown in FIGS. 4 and 5 in particular, a large number of identical printing layers 5, such as characters, figures, symbols, or combinations thereof, are arranged vertically and horizontally. Ru. This printed layer 5 may be produced using conventional printing techniques such as offset printing or screen printing.

Furthermore, perforations 6 for cutting are formed between the multiple arrays of the printed layers 5. This cutting perforation 6 is provided to facilitate dividing the seal 1 into individual sheets.

Next, an example of the manufacturing process of the above-mentioned seal will be explained in the eighth section.
This will be explained with reference to the figures.

Seal manufacturing device 10 includes a holding reel 11 .
The holding reel 11 holds the strip-shaped base material 102 in a roll shape. One end of this base material 102 is unwound and guided to the coating device 13. In addition, this holding roll 11 holds the base material 102 with a relatively weak force in order to prevent the base material 102 from being unwound from bending.
It is being pulled as if being rolled up.

The coating device 13 includes a main roller 13a, a doctor roller 13b in contact with the side of the roller 13a, and a roller 13c provided below the main roller 13a. do.
That is, the main roller 13a and the doctor roller 1
