DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an information communication body which can be used for post cards, reciprocating post cards, sealed letters, etc., including direct mail (DM). In detail, although the appearance is a normal DM, postcard, reciprocating postcard or envelope, the laminated or folded paper is laminated in a releasable adhesive state (hereinafter referred to as pseudo-adhesion). Therefore, the present invention relates to a method for manufacturing an information communication body capable of mailing while concealing a large amount of information.

[0002]

2. Description of the Related Art In recent years, an information communication body has been used for postal items such as postcards, in which a sheet on which information is displayed is pasted or folded so that a large amount of information is concealed and mailed. Such an information communication body is formed by pseudo-adhesion of opposing information display surfaces of a sheet via a pseudo-adhesion medium, and is manufactured by heating and pressing.

As a heating and pressurizing process, for example, as shown in FIG. 6, a sheet folded between opposed surfaces via a pseudo-adhesive medium passes between a plurality of transport rollers 24 and heater panels 23 provided above and below. Conventionally, a method has been adopted in which heating and pressurization are performed, and after sufficient heating, pressure is applied by a pressure roller 25 to be integrated, or heat and pressure are simultaneously passed through a plurality of heat rollers. The manufacturing method, the pseudo-adhesive medium interposed paper discharged from the folding machine, transport rollers,
The roller is moved across a plurality of rollers such as a pressure roller and a heat roller, and there is a possibility that a part of the paper is erroneously caught by rotation of one of the rollers. In particular, the sheet discharged from the folding machine and folded is not sufficiently bent at the folding line and opens naturally, but such a tendency becomes more remarkable when heat is applied. As a result, the folded sheet was opened during the working process, and sometimes not only was pulled in by the rollers, causing a paper jam, but also the outer surface of the sheet was rubbed against the upper and lower heater panels and printed with toner. There has also been a problem that information such as addresses is stained.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems caused by the method for manufacturing an information communication body, and prevents paper from being opened during a process to prevent paper jams or contamination of printed information. An object of the present invention is to provide a method for manufacturing an information communication body that eliminates generation of non-defective products and significantly improves work efficiency.

[0005]

In order to achieve the above object, a method of manufacturing an information communication body according to the present invention comprises a method of forming a pseudo-adhesive medium between opposed information display surfaces of a sheet having at least two information display surfaces. In the method for manufacturing an information communication body, which is peelably integrated under heating and pressurizing, the paper is flatly pressed while a pseudo adhesive medium is interposed between the superimposed information display surfaces. The method is characterized by including one pressing step, a heating step of heating the pseudo-adhesive medium-interposed sheet pressed flat, and a second pressing step of pressing the heated pseudo-adhesive medium-interposed sheet again. The heating step of heating the pseudo-adhesive medium-interposed paper and the second pressing step of pressing again may be performed simultaneously by using a heat roller or the like.

According to the method for manufacturing an information communication body according to the present invention, in the heating step and the first pressing step before the final second pressing step, the paper on which the pseudo adhesive medium is interposed is firmly fixed. Since the sheets are folded flat, they are not opened carelessly in the subsequent steps, so that there is no occurrence of defective products due to paper jams or stained printed information due to the opening of the sheets during the steps. In the first pressurizing step, in order to reliably bend the sheet on which the pseudo-adhesive medium is interposed at the fold line and promote flattening as a whole, so as not to release the pressing force, the sheet is passed between metal rollers. It is preferable to apply pressure.

It is sectional drawing. FIG. 3A is a cross-sectional view of an information communication body sheet in which a pseudo-adhesion laminated sheet as a pseudo-adhesion medium previously pseudo-bonded is being sandwiched between facing surfaces;
(B) is a sectional view in the folded state. FIG.
(A) is a cross-sectional view of the information communication body sheet before the double-folding of the information communication body sheet in which the pseudo adhesive film as the pseudo-adhesive medium is formed on the information display surface, and (B) is a cross-sectional view of the information communication body sheet in the half-fold state. It is. FIG. 5 is a process chart showing the manufacturing method of the present invention. FIG. 6 is a process chart showing a conventional manufacturing method.

In FIG. 1A, a paper S for an information communication body is shown.
In FIG. 1, a first sheet 1 and a second sheet 2 are connected via a fold line 3, and on the front surface 2a of the second sheet 2, an address and name 4 of a recipient are displayed in addition to a postage stamp column and a postal code column. . Also, on the front surface 1a of the first sheet, various information 5 addressed to an unspecified large number of persons who do not need confidentiality, such as advertisements of the sender and guidance words, are displayed. Next, in FIG. 1 (B), the personal information 6 to be concealed is displayed on the back surfaces 1b and 2b of the paper S for the information communication body, and the paper S for the information communication body has the back surface inside. The fold line 3 is folded in two.

In order to quasi-adhere the folded and opposed 1b and 2b with a pseudo-adhesive medium, the following three methods can be adopted depending on the type of the pseudo-adhesive medium. FIG. 2 (A)
Indicates that a thermoplastic pseudo-adhesive film 7 as a pseudo-adhesive medium is laminated with an adhesive 8 on the back side of the information communication medium paper S on which the personal information to be concealed is displayed. 3 and the state shown in FIG. 2 (B), and the pseudo-adhesion films 7 are pseudo-adhered to each other by performing each of the first pressing step, the heating step, and the second pressing step according to the manufacturing method of the present invention. Glued. When peeling off the completed two-fold postcard, peeling is necessarily started from the interface between the pseudo adhesive films 7. As a starting point of the peeling, if the folding line 3 is folded slightly off from the center, it is possible to obtain FIG.
As shown in (B), since the edges do not completely coincide with each other and the step portion 9 occurs, the separation can be easily started by using the step portion 9. Such a step portion 9 can also be formed by providing a notch at a corner portion of the sheet.

As the pseudo-adhesive film 7, a pseudo-adhesive layer made of a thermoplastic resin such as polyethylene or PVA is formed on one surface of a rigid support such as polypropylene, or the other side of the support. One having a surface provided with a heat-sensitive adhesive layer in advance is exemplified. The former is usually
It is applied to a dry lamination method, and the latter is usually applied to a thermal lamination method.

FIG. 3 shows a case where a pseudo-adhesive laminate sheet X is used as a pseudo-adhesion medium in which a thermo-sensitive adhesive 8 is provided on both outer sides of thermoplastic pseudo-adhesive films 7 which have been pseudo-adhered in advance. As shown in FIG. 3A, the information communication medium paper S is folded in two with the back side inward, and the pseudo-adhesive laminated sheet X is sandwiched between the two to form a sandwich state as shown in FIG. 3B. I do. Then, in this state, by performing each of the first pressing step, the heating step, and the second pressing step according to the manufacturing method of the present invention, the pseudo adhesive laminated sheet X and the back surface 1b of the information communication paper S , 2b are bonded and integrated so that they cannot be peeled off. When peeling off the completed two-fold postcard, if the unbonded portion generated at the edge of the sheet is picked up and opened, the peeling is necessarily started from the interface between the pseudo adhesive films 7.

As the pseudo-adhesive laminated sheet X, for example, polyethylene, EVA, EAA, EEA, polyester, polypropylene, ionomer, polyamide, polyethylene, EVA, EAA, EEA, on both sides of a pseudo-adhesion film 7 made of polyethylene terephthalate and polyethylene etc. One provided with a heat-sensitive adhesive layer 8 made of acryl, methacryl, or the like can be used.

FIG. 4 (A) shows a pseudo-adhesive applied to the back side of the information communication medium paper S on which the personal information to be concealed is displayed and dried to form a pseudo-adhesive coating 10 as a pseudo-adhesive medium.
Is formed, and this is folded into two from the folding line 3 and brought into the state shown in FIG. 4B, and the first pressing step, the heating step, and the second pressing step according to the manufacturing method of the present invention. By performing the above processes, the pseudo-adhesive films 10 are pseudo-adhered to each other. At the time of peeling of the completed two-fold postcard, peeling is inevitably started from the interface between the pseudo adhesive coatings 10 with the stepped portion shown in FIG. As a pseudo-adhesive for forming the pseudo-adhesive film 10, for example, IR (isoprene rubber) or NR (natural rubber)
And a UV-curable transparent varnish type.

Although the above three types of pseudo bonding methods are the mainstream, other than these methods, when heating and pressurizing are required in the manufacturing process, the first pressurizing step according to the manufacturing method of the present invention is used. Each process of a heating process and a second pressurization process can be used.

FIG. 2 shows various pseudo bonding methods as described above.
(B), the paper S for the information communication body in which the pseudo-adhesive medium is interposed in the folded state as shown in FIGS. 3 (B) and 4 (B) is from the left side to the right side as shown in FIG. Each process of the first pressurizing step, the heating step, and the second pressurizing step is performed and finally integrated. That is, the folded sheet S is sent to the upper and lower first pressure rollers 22 having a metal surface by the transport roller 21 and is folded completely flat. The paper pressed flat in this way passes through the oven by the upper and lower heater panels 23 and the upper and lower transport rollers 24, and after being sufficiently heated, is finally finished by the upper and lower second pressing rollers 25 having a metal surface. Then, pseudo bonding and complete non-peeling bonding are performed, and the integration is completed. The finished information communication bodies are sequentially stacked on a stacker or the like (not shown).
The pressing force of each of the first pressure roller 22 and the second pressure roller 25, the temperature of the heater panel 23, and the transport speed of the paper are determined by the material and lamination form of the paper to be processed, the type of the pseudo adhesive medium, It is appropriately selected according to processing conditions such as a formation mode.

The paper S for information communication bodies passing through the oven is completely flat as shown in FIG. 5, so that it is erroneously entangled in the gap between the heater panel 23 and the transport roller 24. It flows without any trouble to the end and is discharged from the second pressure roller 25.

However, in the conventional manufacturing method shown in FIG. 6, the information communication paper S is not folded specifically by the first pressure roller 22 as in the present invention, but is simply folded by a folding machine. Since it is sent to the transfer roller 24 in a state where it has just been removed, it is sent into the oven in a state where it is not completely flat and opened naturally, and inside the oven, it is always transferred to the upper and lower heater panels 23 in a half-open state. It is in contact with the roller 24. Therefore, when the edge of the paper S opened inside enters the slight gap between the heater panel 23 and the transport roller 24 while the paper S passes through the oven, the paper S is caught by the transport roller 24 as it is, causing a paper jam. In addition, the work efficiency may be extremely deteriorated by rubbing against the heater panel 23 and the printing may be stained, and in some cases, a problem may occur in which damages may be made due to delay in delivery.

[0018]

According to the method for manufacturing an information communication body according to the present invention, the information communication medium sheet is firmly and flatly folded via the pseudo-adhesive medium in the pressing step before the heating and pressing steps. Therefore, there is no inadvertent opening in the subsequent steps. Accordingly, the paper does not get caught in the various rollers during the above-mentioned process, causing paper jam, and the information printed by the toner is not contaminated, so that the working efficiency is remarkably improved.
