DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of laminating a printed material with gloss and a method of manufacturing an information communication body using the same. Specifically, the appearance is a normal DM, postcard,
Despite being a reciprocating postcard or sealed letter, multiple layers of laminated or folded paper are releasably stacked, so pseudo-adhesion for manufacturing information communication bodies that can hide a large amount of information and can be mailed The present invention relates to a method for laminating a sheet and a method for manufacturing an information communication body using the same.

[0002]

2. Description of the Related Art Conventionally, the surface of a printed material is laminated with a film by a method of using a heat roller for simultaneous heating and pressurizing or a method of heating by a heater panel and then pressurizing by a pressurizing roller. Also, in postal items such as recent postcards, an information communication body that can fold or cut a sheet on which a plurality of pieces of information are written and glue so that a large amount of information can be peeled off (hereinafter referred to as “pseudo-glue”) for mailing is often used. Began to be. The recipient of the information communication body can easily peel off the superimposed surface of the laminated films (hereinafter, pseudo-adhesive sheet) and can check the information inside.

[0003]

By the way, in recent postal matters such as printed matters and postcards, printing of personal information such as the address of the recipient, ruled lines, frameworks, illustrations and photographs is performed by a printer linked to a computer. There have been so many cases. The surface of the printed paper is very weak to heat, and when subjected to the heat and pressure treatment of the heat roller, the printing toner melts and transfers to the heat roll. Then, the transferred printing toner is transferred as it is to the subsequent surface, and the transfer is continuously repeated, thereby causing staining. Also, in the case of a heater panel, the printing toner in contact with the panel is melted by heat and is easily scraped off and flows to contaminate the paper surface. In addition, the scraped printing toner gradually accumulates on the heater panel and becomes jammed. It may also cause the like. In view of the above problems, the present invention provides a laminating method that prevents contamination of a paper surface due to heat and incidents such as a paper jam that accompanies the same and has high working efficiency without contamination, and a method for manufacturing an information communication body using the same. It is intended to be.

[0004]

In order to achieve the above object, the present invention provides a laminating method in which a pseudo-adhesive sheet is aligned with the surface of a continuously fed sheet and continuously between heater panels arranged opposite to each other. In this method, the sheet is conveyed so that the heater panel and the sheet do not come into contact with each other, heated, and pressed by at least a roller at the discharge port to laminate the pseudo adhesive sheet on the sheet surface in a non-peelable manner. It should be noted that if the pseudo adhesive sheet is heated before the paper and the pseudo adhesive sheet are aligned by the laminating method to exhibit the adhesiveness in advance, laminating becomes easier. Furthermore, in order to achieve the above object, the method of manufacturing an information communication body of the present invention is capable of cutting the paper laminated by the laminating method into unit papers, folding or cutting and laminating, and pressurizing or heating / pressing to be peelable. It is characterized by pseudo bonding to Further, in the method of manufacturing the information communication body, the sheet may be cut into unit sheets after pseudo-adhering the sheets, or the cutting may be dispersed before and after each process and cut into unit sheets stepwise. In addition, this laminating method is not only applied to a pseudo adhesive sheet for the purpose of manufacturing an information communication body, but can also be widely applied to, for example, ordinary print laminating films.

The paper used in the present invention is a known paper used for ordinary printing. The form of the sheet may be a long continuous sheet or a cut plain sheet. The printing method in which the effect of the present invention is remarkably exhibited is a method of fixing toner on a paper surface by printing or printing by heating. However, the present invention is also effective in a printing method using a known printing ink such as offset printing, gravure printing, and rotary printing, and a printing ink other than a normal drying method, for example, a drying method by ultraviolet curing.

The pseudo adhesive sheet used in the present invention is, for example, as shown in FIG.
A thermal laminate type pseudo-adhesive sheet having a heat-sensitive adhesive layer 61 provided on one side of the thermal adhesive layer 61 in advance is used. In addition, PE, EVA,
A pseudo adhesive layer 62 based on EAA, EEA, polyamide, ionomer, acrylic, or the like is formed. The configuration of the pseudo adhesive sheet is not limited to a three-layer configuration as a whole as shown in FIG. 9, but may be a one-layer, two-layer, or four-layer configuration. This pseudo-adhesive sheet is a sheet in which the heat-sensitive adhesive layer is melted and adhered to the paper surface when the heat-sensitive adhesive layer is placed on the paper surface and heated and pressurized. After lamination, the pseudo-adhesive sheets are folded so that they face each other. Pseudo-adhesion when cut and layered, pressed or heated / pressed.

[0007] The information communication body manufactured by the present invention may be a two-fold or three-fold (Z-fold / wind-fold), and further folded forms (bellows-fold, roll-fold, double-folding, or a mixture thereof). Yes, and there are also those that are cut and piled up, and those that are folded and cut and piled up. Also, any opposing surface of the multi-layered paper is pseudo-adhered, and depending on the opposing surface, it can be completely adhered non-peelable with heat-sensitive or pressure-sensitive adhesive or adhesive, or free without any operation. It doesn't matter. The selection of such a form or style is designed as needed according to the purpose of use of the information communication body to be manufactured, the advertising effect, and the like, and is not limited. As the adhesive for complete non-peeling adhesion, a film-like adhesive can be suitably used. At this time, the adhesive alone may be in the form of a film, or an adhesive layer may be formed on both sides of a core material made of plastic, paper, cloth, or the like. A configuration may be adopted in which the adhesiveness is exerted by applying conditions such as pressure or humidity, and the adhesive oozes out to the other surface to form double-sided adhesion.

A silicon roller is preferably used as the conveying roller used in the present invention, and a heater panel having a substantially rectangular parallelepiped plate shape and a surface coated with Teflon (registered trademark) can be suitably used. These transport rollers and heater panels are vertically opposed as shown in FIG. 2, and are alternately arranged in the horizontal direction. At this time, the heater panel is arranged at a distance from the path of the sheet passing through the transport roller, so that the heater panel does not come into contact with the sheet. Therefore, even if the print toner is excessively heated, the heater panel may be scraped off or transferred. There is no. Similarly, when the pseudo bonding after lamination is performed by heating and pressurizing, if the heater panel is arranged at a distance from the transport path of the information communication body as shown in FIG. More efficient.

[0009]

According to the laminating method of the present invention, when laminating by heating and pressurizing the printed or printed paper with toner or the like, even if the heater panel is overheated, the paper is applied to the heater panel. Since there is no contact, contamination due to transfer or flow of toner or the like does not occur. When the pseudo bonding is performed at a temperature higher than the softening and melting temperature of the toner or the like, according to the present invention, the information communication body does not come into contact with the high-temperature heater panel. No pollution by flow or flow.

First, referring to FIGS. 1 to 3, a case in which the most basic form of a two-fold postcard in an information communication body is manufactured from a long sheet S will be described. In FIG. 1A, a sheet S is a unit sheet t in which a postcard-size paper piece 1 and a paper piece 2 are connected in a horizontal direction via a fold line 3 and connected in a vertical direction via a fold line 10. In addition to a postage stamp field and a postal code field, the address and name 7 of the recipient are printed on the surface of the paper piece 1 by a printer linked to a computer. Also, on the surface of the paper sheet 2, various information 8 such as the advertisement of the sender is printed. In FIG. 1B, the information of the recipient who needs confidentiality is printed as hidden information 9 together with various other information on the back of the paper sheets 1 and 2 by a printer linked to a computer.
Printed. A marginal hole 5 for transporting the paper S to each process is provided outside the paper pieces 1 and 2,
This part is finally cut off from the cutting line 6 and removed. This sheet S is folded and stored in a bellows shape at a folding line 10 in the horizontal direction in the figure for each unit sheet t or every 2-3 unit sheets.

Next, as shown in FIG. 2, the paper S on which printing, printing, etc. has been completed is placed on a stocker 11 at the lower left, pulled up and pulled into a roll 12 for aligning with the pseudo adhesive sheet F with its back side up. . The sheet S is continuously covered by the pseudo-adhesion sheet F on the entire back surface by the alignment roll 12, and is conveyed to the subsequent heating step. The conveying roller 14 is provided without touching the vertically symmetrically arranged heater panels 13, 13. As a result, it moves while being heated to the right in the figure. Then, after being sufficiently heated, the back surface of the sheet S and the pseudo-adhesive sheet F are completely adhered by the pressure roller 15 at the discharge port via the heat-sensitive adhesive 61 (see FIG. 9) provided on the pseudo-adhesive sheet F so that they cannot be peeled off. Then the lamination is completed.

[0013] The sheet S, on which the lamination is completed, is wound into, for example, a roll and sent to the subsequent pseudo bonding step.
As shown in FIG. 3, the sheet S is installed in a roll shape at the lower left in the figure, folded in two from the fold line 3 by an angle 16 or the like, and drawn into the nip roll 17. Subsequently, the heater panel 18 is moved while being heated rightward in the figure by the transport roller 19 without touching between the heater panels 18 symmetrically arranged vertically. Then, after being sufficiently heated, they are folded by the pressure roller 20 and the pseudo adhesive sheets F facing each other are pseudo bonded. The unnecessary marginal hole 5 of the paper S is cut off from the perforated line 6 by the following slitter 21 and removed, and is further cut by the subsequent roll cutter 22 along the folding line 10 for each unit paper t. The two-fold postcard information communication bodies X thus completed are sequentially stacked on the stocker 23.

In the above-described manufacturing method, the sheet S is wound into a roll after the lamination is completed and the process is moved to the step of pseudo bonding at another line, but may be directly connected to the step of pseudo bonding after the lamination is completed. Further, the roll S may be provided before the heating in the pseudo bonding step, and the sheet S may be cut into unit sheets t before being transported between the heater panels 18. In this case, as in the case of a flat sheet S described later, if the transport rollers 18 in the horizontal direction are arranged at a small interval, the information communication body can be moved between the transport rollers 18 without contacting the heater panel 18. Since it moves, the printing or printing on the surface of the information communication body X is not stained. In the case of an information communication body that is folded in two or more, a pseudo-bonded surface, a completely bonded surface, or a free surface may be present on the front and back surfaces of a printed sheet. The adhesive sheet F, the heat-sensitive or pressure-sensitive adhesive sheet or the pressure-sensitive adhesive sheet can be fed out from the lower side of the process, and the alignment and lamination of both sides of the sheet with the pseudo-bonding sheet F and various types of bonding / adhesive sheets can be performed at one time.

Next, referring to FIG. 4 to FIG.
Lamination method and two of the most basic information communication bodies
A method for manufacturing a folded postcard will be described. FIGS. 4A and 4B are a front view and a back view of a plain paper S printed in a state in which postcard-sized paper pieces 31 and 32 are connected via a folding line 33, respectively. As shown in FIG. 4A, a postage stamp column and a postal code column are displayed on the surface of the paper piece 31, and the address and name 34 of the recipient are printed. Various information 35 such as the advertisement of the sender is printed on the surface of the paper piece 32. Further, as shown in FIG. 4B, information that requires the recipient to be confidential is printed and printed as concealment information 36 together with various other information on the back surfaces of the paper pieces 31 and 32 by a printer linked to a computer.

As shown in FIG. 5, the paper S is stacked on the stocker 40 on the left side in the figure, sent out one by one to the right alignment roller 42 by the paper feed roller 41, and fed out from below the transport line of the paper S. It is arranged on the pseudo adhesive sheet F. At this time, as shown in FIGS.
The feeding pitch of the paper S is set slightly earlier, and the paper S is fed so that the front of the paper S to be sent next slightly overlaps the rear of the paper S sent earlier. In this state, if the sheet S is sufficiently heated together with the pseudo adhesive sheet F and pressed by the pressure roller 45 at the discharge port, the paper S can be laminated in a continuous state. Thereafter, the sheet is cut individually, folding is completed by a folding machine or the like, and the process proceeds to the subsequent pseudo bonding step.

In the pseudo bonding step, as shown in FIG. 6, after the sheets S which have been individually cut after lamination are folded into two by a folding machine, they are stacked on a stocker 39 on the left side in the figure, and one sheet at a time on the right side by a paper feed roller 46. It is sent to the pressure roller 47. In the subsequent heating step, the width of the heater panel 48 is set to be narrow, and the interval between the arrangement of the transport rollers 49 is set to be narrower than the length of the information communication body X. Pressure roller 47 at the outlet
Then, the paper is conveyed after being heated sufficiently, and the pseudo bonding is completed by pressurization, and is stored in the stocker 50 on the right side.

The present invention is not limited to the above embodiment. For example, as shown in FIG. 8, if the pseudo adhesive sheet F is heated beforehand by the heater panel 56 or the like in front of the alignment roll 52, the alignment roll can be adhered to the sheet S to some extent, and the displacement during conveyance can be eliminated. Further, if the role of the pressure roll is added to the transport roll 54, the sheet S and the pseudo adhesive sheet F can be further securely bonded. Further, if the shape of the heater panel is formed as a curve without corners as shown in each figure, the toner and ink will not be scraped off even if the sheet touches the sheet by mistake. Each step may be a separate line as shown in FIGS. 2 and 3 for the long sheet S, but these lines may be connected.
Similarly, the plain paper S requires cutting and folding steps (not shown) between the steps shown in FIGS. 5 and 6, but all of these steps are constituted by a series of connected lines. No problem. The roll cutter 22 in FIG. 3 may be replaced with another known cutting method (for example, a cutting method using shearing of a cutting bar).

[0019]

According to the laminating method of the present invention, when printing and printing with toner or the like and laminating the paper by heating and pressing, even if the heater panel is overheated, the paper is heated. Since there is no contact with the panel, there is no contamination due to transfer or flow of toner or the like. When the pseudo bonding is performed at a temperature higher than the softening and melting temperature of the toner or the like, according to the present invention, the information communication body does not come into contact with the high-temperature heater panel. No fouling due to flow. Further, according to the present invention, the present invention can be applied to a known printing ink, and an information communication body can be manufactured in a more beautiful state than before.
