Abstract

PROBLEM TO BE SOLVED: To prevent an adhesive from adhering to a machine blade or the like when a part to which the adhesive is applied beforehand is processed as specified by applying the adhesive previously to a specified face of a sheet in a freely peelable manner and removing the adhesive applied to an area scheduled for processing of the sheet or making the application of the adhesive in the area less dense than that in another adhesive-applied part. SOLUTION: Each of sheets 1 for lapped adhesion comprises a long-size sheet base material 2 with an adhesive applied to the entire first/second surfaces in a freely peelable manner and so many pieces of the sheet 1 are connected to each other in such a way that the sheets 1 are demarcated by plural demarcation cutting parts 4 formed in the width direction. In addition, the sheets 1 are demarcated by the strips of the demarcation cutting part 4 formed in the longitudinal direction, as a body part and a marginal part. Each of the demarcation cutting parts 4 in the longitudinal and transverse directions, is cut using a cutting blade, and regions 4a scheduled for processing are set in the cut parts. Processed regions 5a are set at the marginal part on both sides of the sheet base material 2. The adhesive applied to each of the regions 4a schedules for processing shows a lower application density compared with the adhesive-applied part of the other adhesive region.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of peeling off the entire surface or a predetermined portion of a superimposed surface by folding, cutting or laminating one sheet through a folding portion, or laminating separate sheets. The present invention relates to a sheet for superimposition bonding which forms a superimposition card, a postcard and the like having a notification information or the like on a superimposed surface.

[0002]

2. Description of the Related Art Conventionally, a superposition bonding sheet in which a superimposed surface is used as a concealment information recording portion has been designed so that the notification information provided in the concealment information recording portion is protected by a third party so that a third party cannot view the notification information. Often used when contacting.
For example, in the case where the overlapping adhesive sheet is configured as an information concealed postcard, the sender writes information in the concealed information writing section, and then pastes the overlapped surfaces together in a peelable manner, and the recipient places the overlapped surface on the information. The concealment information can be confirmed by peeling it off.

[0003] As a sheet for superimposition bonding represented by this information hiding postcard, a sheet in which a plurality of superimposed paper pieces are connected in a foldable manner is usually used. To be releasably bonded, each superposed surface has no adhesive property in an exposed state, but is applied with an adhesive that is releasably bonded when the superposed surfaces are pressed in a superposed state. . Therefore, when the overlapping adhesive sheets are pressed with a dry sealer or the like in the overlapped state, the laminated paper pieces are releasably adhered to each other by the adhesive, and an information hiding postcard or the like is obtained.

[0004]

In the case of producing such an overlap bonding sheet, generally, marginal portions on both sides of a long sheet base material to which an adhesive to be peelably bonded is applied in advance. The connection hole (marginal hole) for connecting to the tractor pin for transfer is given to the
In the individual sheets for superimposition bonding, perforation processing is performed to divide each superimposed paper piece and form a folded portion, and notch processing to form a peeling opening for easily peeling the superimposed paper pieces in the superimposed state. And so on.

However, in the case where predetermined processing such as marginal hole processing, sewing line processing, and notch processing is performed as post-processing on a portion to which the adhesive has been applied in advance, a die cutting blade or the like for performing such processing is required. Adhesive adheres to the sewing machine blade, causing cut defects, or the adhesive sticks out on the opposite side of the processed side of the overlap bonding sheet,
There are some inconveniences such as the fact that the front and back surfaces of each sheet adhere to each other, that is, a so-called blocking phenomenon occurs.

Accordingly, the present invention provides a method for applying an adhesive to a die cutting blade or a sewing machine blade when performing predetermined processing such as marginal hole processing, sewing line processing, or notch processing on a portion to which the adhesive has been applied in advance. An object of the present invention is to provide a lap bonding sheet having a structure in which the adhesive is not attached and the adhesive does not protrude to the side opposite to the side to be processed.

[0007]

SUMMARY OF THE INVENTION In view of the above problems, the inventors of the present invention have developed a method for forming a predetermined area such as a marginal hole, a perforated line, a notch, etc. By setting a processing scheduled area where processing is performed, the adhesive in this area is completely removed or partially removed, and the application density is made coarser than other adhesive applied parts, The inventors have found that the object can be achieved, and arrived at the present invention.

In other words, the adhesive sheet for lamination according to the present invention is a sheet for adhesive lamination in which an adhesive for releasably bonding is applied to a predetermined surface of the sheet in advance and subjected to a predetermined processing. Thus, the adhesive applied to the area to be processed of the sheet is removed or the application density is formed to be lower than that of another adhesive applied portion.

Therefore, according to the lap-bonding sheet of the present invention, the adhesive is not present in the area to be processed such as the marginal hole, the perforation line, the notch, or the like. Since the amount of adhesive per unit area is smaller than in the case of bonding and the application density is formed coarsely, the adhesive is applied to the die cutting blade or the sewing machine blade when predetermined processing is performed on the processing scheduled area. Does not adhere at all, or even if it adheres, the coating density is coarse, so the amount of adhesion is small.Also, the adhesive does not protrude to the opposite side of the side to be processed. It can be suitably prevented.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the sheet for bonding and bonding according to the present invention will be described in more detail based on preferred embodiments. In addition,
Here, FIG. 1 is a flow chart of creating a sheet for superimposition bonding of the present invention, which constitutes the “three-fold information hiding postcard”, (a) is an explanatory view showing a state in which an adhesive is applied to the sheet substrate surface, B) is an explanatory diagram of a state in which the planned processing area is set,
(C) is a state explanatory view in which predetermined processing has been performed on the processing scheduled area, FIG. 2 is a state explanatory view on the back side of FIG. 1, and FIG. 3 is a cross-sectional view taken along line XX in (C) of FIG. 4 is an explanatory view of the use state of the sheet for superimposition bonding of FIG. 1, FIG. 5 is an explanatory view of the use state of the sheet for superimposition adhesion constituting another "3-fold information hiding postcard", and FIG. It is a use explanatory view of the sheet | seat for superposition | adhesion which comprises "3 fold information hiding postcard".

The production flow charts shown in FIGS. 1 and 2 relate to a sheet for superimposition bonding constituted as a "tri-fold information hiding postcard". First, as shown in (a), each of the sheets for superimposition bonding 1 is a long sheet base material 2 coated with an adhesive 3 that is releasably adhered to the entire front and back surfaces.
Is divided by the plurality of section cutting sections 4 applied in the width direction in a state in which a large number of the overlapping adhesive sheets 1 are connected, and furthermore, the main section is divided by two section cutting sections 4 applied in the length direction. It is divided into a marginal part.

As shown in (b), each of the vertical and horizontal section cut portions 4 is cut by a cutting blade, so that a scheduled processing area 4a is set in these portions, and a long portion is set. In the marginal portions on both sides of the sheet base material 2, processing planned areas 5 a for setting marginal holes 5 (see (c)) for connecting to tractor pins for transferring the sheet base material 2 are set. In addition, each of the superimposing adhesive sheets 1 is further superimposed on a superimposed paper piece a,
A processing scheduled area 6a for setting two perforation lines 6 (see (c)) for partitioning into a middle-sized paper piece b and a lower-order paper piece c is set, and a notch 7 for forming a peeling opening is provided.
A scheduled processing area 7a for performing [see (c)] is set.

The adhesive applied to each set area to be processed is not completely removed and is formed with a higher application density than the adhesive applied portion in the other adhesive areas.
In the case of the present embodiment, as shown in FIG.
a, 5a, and 7a, the adhesive 3 is completely removed, and the area to be processed 6a is partially removed while leaving the adhesive 3 in a halftone dot shape. Also, it is formed with a rough coating density.

Regarding the area and the shape of the planned processing area, the planned processing areas 4a and 6a each have a width of 1 mm in consideration of the cutting blade, the blade width of the sewing blade, the allowable position of the processing, the bonding range of the overlap bonding sheet, and the like. It was a rectangular shape of the order. In addition, although the planned processing area 5a has a concentric shape slightly larger than the diameter of the marginal hole 5, it may be, for example, a rectangle having a width enough to include the marginal hole 5. Further, the area 7a to be processed has a triangular shape which is similar to the shape of the notch 7 and is slightly larger.

However, the present invention is not limited to these, and does not impair the function of the sheet for laminating and bonding, and arbitrarily determines the area and shape of the region to be processed so as to obtain a desired effect. is there. In addition, the setting of the processing scheduled area may be performed when the adhesive is applied to the front and back surfaces of the sheet base material, or only one of the processing surface side of the portion to be processed or the opposite side surface. As shown in the examples, it is most effective and preferable to set them on the front and back surfaces of the sheet base material.

Further, it is necessary to completely remove the adhesive in the area to be processed and completely eliminate the adhesive force of the portion or to reduce the application density of the adhesive so that the adhesive force of the portion remains to some extent.
The configuration, usage, or processing method and type of the sheet for laminating and bonding are appropriately selected depending on the characteristics of the processing apparatus and the like, as long as a desired effect can be obtained, and the present invention is limited to the selection of this embodiment. Not something.

As a method for removing the adhesive, there is a method in which a cutting roll or a blade for reverse rotation is brought into contact with a portion to which the adhesive is applied, and the adhesive is partially scraped off. It is preferable to sublimate the adhesive in the irradiation section. According to this method, adjustment of the laser irradiation energy amount (for example, 50 W to 150 W), adjustment of the output pulse width (for example, 10 μm to 25 μm), or
By irradiating the laser by an irradiation path operation using a predetermined optical guide system such as a variable mask or a rotating mirror, the sublimation amount and the sublimation pattern of the adhesive in the laser irradiation section can be freely controlled. Therefore, in the portion irradiated with the laser, the thickness of the coating layer of the adhesive is reduced, or a desired coating pattern (sublimation pattern corresponding to negative / positive) such as halftone, stripe, or matrix is realized. The application amount of the adhesive per unit area decreases, and the application density of the adhesive in the region to be processed becomes relatively coarse as compared with the non-irradiated portion. Note that a laser irradiation apparatus which is recently used for processing a sheet or the like on a perforated line or a watermark pattern on a sheet is good, and a so-called carbon dioxide gas laser is most suitable.

Then, as shown in (c), the marginal hole 5, the sewing line 6, and the notch 7 are respectively provided in the planned processing regions 4a, 5a, 6a, 7a thus set.
Is applied. However, in the processing scheduled area 4a, in the state of (c), the section cutting section 4 is not cut by the cutting blade. No defective cutting or the like occurs in each processed portion of the overlap bonding sheet thus formed, and no adhesive does not protrude to the side opposite to the side to be processed.

As shown in FIG. 4, when the overlapping adhesive sheet 1 is used, predetermined printing and printing information (not shown) are applied, and after the marginal portion including the planned processing area 5a is cut, The upper sheet a, the middle sheet b, and the lower sheet c are folded in a Z-shape via the two perforation lines 6, and the respective overlapping surfaces are releasably bonded by pressing with a dry sealer. It is configured as a "tri-fold information hiding postcard."

The following are some examples of application of the lap-bonding sheet of the present invention. For example, the overlap bonding sheet 1 constituting another “three-fold information hiding postcard” shown in FIG. 5 includes an upper sheet a, a middle sheet b, and a lower sheet c that are folded in a Z-shape. In the same manner as in the embodiment, a processing scheduled area such as cutting of a section cutting portion, a perforation line, a notch, and the like are set, and a medium-sized paper sheet b which is regarded as a postcard body.
The area (not shown) to be processed by the die-cutting process for forming the display window hole 8 that allows the postcard display H provided in the printer to be viewed through the upper-order piece of paper a is set.

Further, the sheet 1 for superimposing and bonding, which constitutes another "tri-fold information hiding postcard" shown in FIG.
It is composed of a cut-out upper sheet a, a middle sheet b, and a lower sheet c, which are also set with a processing scheduled area such as a section cut section, a notch, and the like, and also include a postcard display H. A predetermined area 10 in which a high-order paper piece a and a middle-size paper piece b, which looks like a postcard body, are strongly adhered so as to be difficult to peel off.
A processing area (not shown) for processing the slit 9 for partitioning and separating the strippable area 11 from other areas is set.

The above-described embodiment of the sheet for superimposing and bonding according to the present invention is a case where it is configured as a "3-fold information hiding postcard", but the present invention is not limited to this. One sheet can be folded through a folding unit, such as a "folded information concealed postcard" made of paper pieces, or a "partial folded information concealed postcard" made of two superimposed paper pieces of different sizes, or The present invention can be applied to any device in which the entire surface or a predetermined portion of the superposed surface is releasably adhered by, for example, laminating separate sheets.

[0023]

As described above, according to the lap bonding sheet of the present invention, marginal holes, perforation lines,
If there is no adhesive in the area to be processed such as a notch,
Alternatively, even if it is present, the predetermined processing is performed on the processing target area by the fact that the adhesive amount per unit area is smaller than that in the case where the adhesive is normally peelably bonded and the application density is formed roughly. When the adhesive does not adhere to the die-cutting blade or the sewing machine blade at all, or even if it adheres, the application density is low, so the amount of adhesion is small, and the adhesive sticks out to the side opposite to the side to be processed. Does not occur,
It has the effect of preventing cutting defects and blocking phenomenon.
