Description

[Detailed description of the invention] The present invention relates to a continuous label manufacturing method.

Various methods for manufacturing labels have been proposed and are well known, but there are methods in which the label paper is temporarily stopped during lithographic printing or lithographic printing, or methods in which the ink printed on the label paper is This is a method in which the transparent film is left on the label paper while it is still wet.

The former method has the disadvantage of inefficiency due to twice-stopping of the label paper, while the latter method has the disadvantage that undried ink is scattered by the presence of the transparent film, resulting in a noticeable problem where only defective products are obtained. There are disadvantages.

The present invention proposes a method for manufacturing labels that eliminates the above-mentioned disadvantages of the well-known method described above.

To explain an example of implementation O with drawings, the back side of a tape-shaped long printing paper 1 is lined with a tape-like long release paper 2 of the same width in advance via a pressure-sensitive adhesive 3, Wind it around the winding shaft a.

The long printing paper 1 wound around the winding shaft a is pulled out and printed by a printing roller b to display desired figures, characters, etc. b1
The printing paper 101 is obtained through a first step in which the paper is printed.

The ink printed on the printing paper 101 is dried either forcibly or naturally. In the case of forced drying, it is passed through a drying device (not shown), and in the case of natural drying, printing is performed with quick-drying ink. If you do this, you can dry it directly.

The printing paper 101 on which the printed ink has dried is sent to a second step where a portion of the transparent synthetic resin film 4 is attached.

The back side of the tape-like long transparent resin film 4 is lined with a tape-like long release paper 5 of the same width via a pressure-sensitive adhesive 7, and the film is wound around the winding shaft C. .

The release paper 5 lining the film 4 is provided with parallel cuts 6 in the longitudinal direction in advance, so that the film 4 is
While pulling it out, remove the unnecessary part 5-1 of the release paper 5 at the cut line.
is peeled off from the film 4 to expose the pressure sensitive adhesive 7 on the back side of the film.

The pressure-sensitive adhesive 7 is exposed only in the peeled unnecessary portion 5-1, so that the pressure-sensitive adhesive 7 is exposed narrowly in the longitudinal direction of the film 4.

Therefore, the exposed position of the pressure-sensitive adhesive 7, that is, the position of the unnecessary part 5-1 of the release paper 5, is set to a position that does not match the indication b1 printed on the printed paper 101, and the indication b1 of the printed paper 101 is removed. The pressure-sensitive adhesive 7 exposed along a part of the printing surface side, that is, one edge of the printing surface side of the printing paper 101 is pasted with an adhesive roller d, and a part of the film 4 is attached to the printing paper. Proceed to the third step of pasting it on a part of the printing surface side of 101 and rotary cutting.

The printing paper 101 and the transparent resin film 4, which are partially attached to each other as described above, are cut into the desired shape and size by a rotary cutting roller e, leaving the tape-like long release paper 2 behind. The residue 10 of the printing paper 101 is rotary cut and removed by a peeling roller f.
1-1. Peel off the residue 4-1 of the transparent resin film 4 and the residue 5-2 of the release paper 5, and remove the unnecessary part 5 of the release paper 5.
-1 together with the winding shaft g.

The labels thus formed into the desired shape and size are arranged on the tape-like long release paper 2 and wound onto the final winding shaft h.

The rotary cutting in this third step is performed using a rotary cutting roller e.
The cutting blade el is provided with a cutting blade el, and the roller is rotated to perform cutting, and the cutting blade e1 cuts the outer ring along the marking b1 of the printing paper 101.

Therefore, the label is shaped similar to the outline of the display b1 and placed on the release paper 2.

FIG. 1 shows an outline of the method for manufacturing a label of the present invention, in which only one label is placed on each tape-shaped long release paper 2, but the present invention is not limited to this. For example, the release paper 5 is made with many cuts 6, the rotary cutting roller e is equipped with many cutting blades e1, and the printing paper 1 is
01 and a part of the transparent synthetic resin film 4 are mutually pasted to a part of the printing surface side of the printing paper 101 that is outside the marking b1, and the outer ring of the marking is cut out. By arranging the cuts 6 and the cutting roller e, a large number of labels are arranged in a certain shape on the tape-like long release paper 2, and a product as shown in FIG. 3 is obtained.

Next, if we explain the product with reference to Figure 2, Figure 2 is similar to Figure 1.
This shows one of the labels obtained by the method shown in the figure, which was obtained by cutting a tape-shaped long release paper 2, on which pressure-sensitive adhesives are applied in order from the bottom. agent 3, printing paper 101 having indication b1, release paper 5, transparent synthetic resin film 4 are arranged, and a part of the film and printing paper 101 is along one edge on the printing surface side away from indication b1. They are attached to each other, and the release paper 5 is lined with the film 4 so as to cover the display b1, and the label is cut into a similar shape along the outer ring of the display b1.

Accordingly, when the transparent synthetic resin film 4 and the release paper 5 are rolled up as shown in FIG. 2, the display b1 of the printing paper 10 appears.

FIG. 3 shows an example in which a large number of labels are molded and arranged on a tape-shaped long release paper 2, and a part of the release paper is shown by cutting it.

As described above, the present invention includes the first step of rotary printing, the second step of pasting the printed side of the printing paper and a part of the transparent resin film to each other, and the third step of rotary cutting them. In particular, in the second step, the above-mentioned film is attached after the printed ink has dried, which eliminates the inconvenience of the ink scattering and provides a high-quality label with a good finish. It is effective, and because the first step is rotary printing and the third step is rotary cutting, each part is processed in a continuous assembly line without stopping at all, and products are efficiently obtained. It has the advantage of being able to

Therefore, all the disadvantages of the above-mentioned known methods can be overcome and the intended purpose can be achieved.
