Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mount and a method for manufacturing the same, and particularly relates to a novel multilayer interleaving paper and a method for manufacturing the same. It is something.

Conventionally, the structure of a multilayer mount made by pasting together multiple sheets of paper is publicly known, but since a conventional multilayer mount can only function as a mount if the entire surface is uniformly adhered, it is necessary to provide a non-adhesive part. was unthinkable considering the purpose of the mount.

The challenge is how to adhere the mount evenly.
It is said that a laminate with no non-adhesive portions and no portion #1 *tt is of good quality.

This invention provides a multilayer mount with a completely new structure, which is characterized by intentionally providing non-adhesive parts at appropriate locations contrary to the purpose of conventional mounts, and making the non-adhesive parts removable, and a method for manufacturing the same. It's a trick.

Therefore, the present invention has the following configuration.

That is, laminate paper with letters, figures, etc. printed on both sides or one side was pasted together with a heat-sensitive adhesive applied to predetermined areas, creating a bonded part and a non-bonded part, and the non-bonded part was made removable. A multilayer mount having a non-contacting material GL + min is used, characters, figures, etc. are printed on both sides or one side, and then a heat-sensitive adhesive is applied to both or one of the bonding surfaces to produce a bonding paper, and then, A method for producing a multilayer mount was produced by bonding the bonding surfaces of these bonding papers by thermocompression bonding.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

Figures 1 to 4 show a two-layer mount according to the present invention. Figure 1 is a perspective view with the non-adhesive part partially peeled off, and Figure 2 is a top and bottom laminate of the laminate. 3 and 4 are cross-sectional views taken along line AA and line B-B in FIG. 1, respectively.

The interleaving paper 1 is made by pasting together the upper paper 2 and the lower paper 3 of the interleaving paper,
The upper paper 2 has a printed portion 4 of characters, figures, etc. printed on the upper surface, and a heat-sensitive adhesive 5 is applied to the lower surface (laminated surface). It has a non-adhesive portion 7 which is not coated. If necessary, the non-adhesive portion 7 is provided with small holes for degassing at appropriate intervals to remove steam and the like that may be present when the parts are bonded together. Further, the upper paper 2 is provided with perforations 8 and cuts 9 in order to facilitate peeling off of the non-adhesive portion 7.

On the other hand, the bottom paper 3 has a bonded part 6a formed by applying the heat-sensitive adhesive 5 on the upper surface (laminated surface) and a non-bonded part 7a to which the heat-sensitive adhesive 5 is not applied, and further has a non-bonded part 7a on the top surface.
A printed portion 4a of characters, figures, etc. is printed on. The interleaving paper 1 is formed by thermocompression bonding the top paper 2 and bottom paper 3 of these structures with a heat-sensitive adhesive 5.

Since the interleaf paper 1 according to the present invention is constructed as described above, it is simply a sheet of normal paper mount which is simply printed and has perforations 8 provided at arbitrary locations on the upper surface. However, although the inside of the perforation 8 is a non-contact part 7.7a, the top paper 2 can be easily separated from the bottom paper 3 from the cut 9 along the perforation 8. When the non-adhesive part of the upper paper 2 is separated, the perforation 8 of the upper paper 2 becomes a cutting frame, and the non-adhesive part 7a of the upper surface (inner surface) of the lower paper 3 is exposed, and the print printed on this non-adhesive part 7a can be removed. Part 4a is broken.

The surface and printing portion may be printed on both sides of the upper paper 2 and the lower paper 3, respectively, or may be printed on only one side of both. Further, it is preferable to apply the heat-sensitive adhesive 5 to the abutting surfaces of the upper paper 2 and the lower paper 3, which will be the bonded parts, but it may be applied only to either one of them. moreover,
The small holes 16 for deaeration can be provided not only in the upper paper 2 but also in the non-adhesive portion 7a of the lower paper 3 as appropriate. Deaeration small hole 16
The size and number of can be selected arbitrarily, but approximately 1
It is preferable to provide cnl at a ratio of 1 (1/it).

Next, a method for manufacturing the mount of the present invention having the above structure will be explained.

FIG. 5 shows the method of printing on the top paper 2 and the bottom paper 3 and the method of applying the heat-sensitive adhesive 5. First, to explain the top paper 2, characters are printed on the top paper 2 in the same way as in known letterpress printing. , In order to print a printed part such as a figure, a paper mold is taken from the original plate in advance, and a lead plate 10 is cast by pouring lead into the mold, and the lead plate 10 is rolled into a roll 11.
A predetermined printing is performed on the upper and lower surfaces of the upper paper 2 using the printing roll 12 wound around the upper paper 2 to produce the upper paper 2a.

Next, a lead plate 13 for applying an adhesive is produced in the same manner as the method for producing a lead plate for printing, with the adhesive portion 6 of the lower bonding surface of the upper paper 2a being regarded as a printing part. This lead plate 13 is wound around a roll 14 to prepare an adhesive application roll 15. With this adhesive application roll 15, the upper paper 2a
By replacing the printing ink with heat-sensitive adhesive on the bottom surface (bonding surface),
Adhesive is printed and applied using a printing method. That is, the present invention is characterized in that the heat-sensitive adhesive 5 is applied by printing.

Furthermore, in the next step, small holes 16 for degassing are punched in the non-adhesive portions of the upper paper 2a where no adhesive has been printed and applied. The small holes 16 for deaeration can be formed by passing needles 17 between a roll 18 and a presser roll 18a in which needles 17 are implanted at predetermined intervals.

In addition, when the upper paper 2 and the lower paper 3 are pasted together, the small holes 16 for degassing may cause unreleased solvent in the heat-sensitive adhesive 5 and moisture contained in the paper to prevent adhesion during thermocompression bonding. It is formed for degassing in order to prevent bulging in a concentrated area, so even if the area of the non-adhesive part is small or a bulging part occurs, it will not affect the product value. If it does not have any effect, the formation of the small deaeration holes 16 can be omitted.

Next, printing on the bottom paper 3 and applying the heat-sensitive adhesive 5 to the upper surface (bonding surface) by the printing method are the same as in the case of 2 sets 2. Printing roll 12 with a pre-fabricated lead plate attached
Then, a predetermined printing section was printed on the upper and lower surfaces of the lower paper 3 to produce the upper paper 3a.Then, the non-adhesive part of the upper surface (laminated surface) was cut out and a lead plate was used as an imprint of 1 digit adhesive. The heat-sensitive adhesive 5 is printed and coated using a coating roll 15, and if necessary, small holes 16 for degassing are formed using a single call 18.

Next, in order to bond the upper paper 2b and the lower paper 3b to which the printing part 4.4a is printed and the heat-sensitive adhesive 5 is applied by the printing method as described above, the heat-sensitive adhesive 5 is applied to the bonding surfaces in advance. Therefore, as shown in FIG. 6, it is sufficient to press the heat rolls 19 and 19a. The top paper 2b and the top paper 3b can be bonded together as a single mount by thermocompression bonding, even though a non-adhesive portion is formed inside, in the same way as a normal mount.

At this time, if a small hole for degassing is made in the non-adhesive glH portion of the top paper 2b, undissipated solvent in the adhesive and moisture in the top and bottom papers will evaporate during thermocompression bonding. It is possible to remove air even when the adhesive is removed, and prevent the unbonded portion from bulging.

Furthermore, in order to facilitate the peeling off of the non-adhesive portion 6 of the upper paper 2 which is the laminated paper in the interleaving paper 1, a sewing machine [=l processing roll 21] provided with a perforation punching blade 20 and a cut forming blade is used. , there are perforations 8 and cuts 9 in this non-adhesive area.
to form. The processing of the perforations 8 and cuts 9 in the non-adhesive portion of the upper paper 2 is not limited to the method described in 2 above, and may be performed by any known method.

Note that the processing of perforations 8, cuts 9, etc. on the non-bonded portions may be omitted if necessary, or only either the perforations or cuts may be formed.

In the embodiment described above, a method for manufacturing a mount made by laminating two sheets of laminated paper has been described, but it is obvious that the method for manufacturing a mount made by laminating three or more sheets can also be carried out in accordance with the above method. , the explanation thereof will be omitted.

Note that the laminated paper constituting the interleaf paper may be synthetic paper as well as ordinary paper.

Since this invention is configured as described above, it can produce the following specific effects.

(1) Since a heat-sensitive adhesive is used for the adhesive, even if the adhesive is applied, it will not adhere until it is thermocompressed, so it can be stacked and continuous application work is possible.

(2) The part of the heat-sensitive adhesive that needs to be removed is part of the plate-cutting process.
Since the printing method uses a roll to print and apply, it is possible to apply accurately and in large quantities.

(3) When providing small holes for deaeration on the upper paper and/or both the upper paper of the laminate paper, it will not bulge during thermocompression bonding and will remain as smooth as a conventional mount. You can get the mount.

(4) Since predetermined areas are made non-adhesive and removable, the printed portion of the bonded surface can be exposed, making it possible to provide a mount suitable for lottery tickets, game cards, etc.
