The postcard is manufactured from the first sheet (1a) and the second sheet (2a) shown in FIG. The 1st sheet | seat (1a) is a strip | belt-shaped paper, and has a structure where many parts equivalent to a postcard continue along a longitudinal direction.

  The second sheet (2a) is a transparent belt-like film, and a transparent first adhesive (28) is applied to one surface of the second sheet (2a), and the adhesive strength is higher than that of the first adhesive (28) to the other surface. A weak transparent second adhesive (29) is applied. The first adhesive (28) is a normal adhesive that cures over time when exposed to air, and the second adhesive (29) is a hot-melt adhesive. The second adhesive (29) is applied in advance to the second sheet (2a) before the second sheet (2a) is set in the laminating apparatus, and the first adhesive (28) is applied to the first sheet (2a). Immediately before laminating 1a) and the second sheet (2a), it is applied to the second sheet (2a) by the application device (8a). Then, the excess solvent component of the applied first adhesive (28) is volatilized by the drying device (8b).

The first sheet (1a) and the second sheet (2a) are dried by a drying device (8b) and then paired along the longitudinal direction in a superposed state via the first adhesive (28). It is pinched by the rollers (8c) and (8d). By this clamping pressure, the first sheet (1a) and the second sheet (2a) are bonded.

After that, the first member (10) and the second member (20) are folded in two with the second member (20) inside, and the first member (10) and the second member (20) are By being heated while being pinched, the inner surfaces of the second member (20) are bonded to each other via the second adhesive (29).
In this postcard, the adhesive force between the inner surfaces of the second member (20) is weaker than the adhesive force between the first member (10) and the second member (20). When the parts on both sides of the second member are pulled outward, the inner surfaces of the second member (20) are peeled apart. In this state, information printed in advance on the inner surface of the first member (10) can be seen through the second adhesive (29), the second member (20), and the first adhesive (28).

  However, in this conventional technique, the first adhesive (28) is a normal adhesive and cannot be left as it is. Therefore, the first adhesive (28) must be applied just before the lamination. For this reason, the laminating apparatus needs to include a coating apparatus (8a) and a drying apparatus (8b), and is increased in size.

  An object of this invention is to provide the film material which can be used for the manufacturing method of the card body which can miniaturize a laminating apparatus.

A film material obtained by setting each adhesive force of the first hot melt adhesive and the second hot melt adhesive so as to be weaker than the adhesive force with the second member. "It is in.

In the method of manufacturing a card body using the film material, the preparation step includes the first sheet in the form of a band and the film material, the first hot melt adhesive is applied to one surface and the second surface is applied to the second surface. The belt-shaped second sheet coated with the hot melt adhesive is prepared. The film material comprises a transparent film body, a first hot melt adhesive applied to one surface of the film body, and a second hot melt adhesive applied to the other surface of the film body, The film body corresponds to the second sheet.
In the bonding step, the first sheet and the second sheet are clamped by a pair of rollers along the longitudinal direction in a superposed state via the first hot melt adhesive. 1 Hot melt adhesive is heated to a molten state. As a result, the first sheet and the second sheet are bonded together. In this step, part of the molten second hot melt adhesive is peeled off from the second sheet and adheres to the roller on the second sheet side.

Thereafter, the second hot melt adhesive is heated to a molten state in a state where the first sheet and the second sheet are folded in two along the longitudinal direction by the forming step.

Further, as in the invention of claim 3, “information is printed on the adhesive surface of the first sheet with the second sheet,
The second sheet is made of a transparent film,
The roller on the second sheet side of the pair of rollers may be heated to a predetermined temperature ”.

In this configuration, the first sheet and the second sheet are pinched by the pair of rollers. Then, since the roller on the second sheet side of the rollers is heated to a predetermined temperature, the first hot melt adhesive melts while being pressed. As a result, the first sheet and the second sheet are bonded together.
And in the state which pulled apart the both sides from the folding line in the said 1st member of the said card body outside, and peeled off the inner surface of the said 2nd member, the said 2nd hot-melt-adhesive, the said 2nd sheet | seat Since the first hot melt adhesive is transparent, the information printed on the adhesive surface of the first sheet can be seen through the first hot melt adhesive.

As described above, in the present invention, the adhesive applied to one surface of the second sheet in order to bond the first sheet and the second sheet in the card body manufacturing method is a hot melt adhesive. From the above, it can be left as it is. The second hot melt adhesive applied to the other surface of the second sheet is partially peeled off from the second sheet while being heated to a molten state while being pressed between a pair of rollers. The second hot melt that adheres to the roller on the second sheet side, but is peeled off from the second sheet and does not adhere to the roller on the second sheet side when the inner surfaces of the second sheet are bonded to each other in the subsequent process. The adhesive is heated to a molten state and used for bonding the inner surfaces of the second sheet.
Therefore, the laminating apparatus for adhering the first sheet and the second sheet does not need to be equipped with an apparatus for applying and drying the adhesive immediately before laminating as in the prior art, and the laminating apparatus is small. It becomes.

[About postcard (1000)]
As shown in FIG. 2, the postcard (1000) shown in FIG. 1 includes a first member (10) folded in a sheet shape and a first hot melt against the inner surface of the first member (10). The second member (20) is bonded with the adhesive (21) and overlapped, and the inner surface of the second member (20) is bonded with the second hot melt adhesive (22). .

And this postcard (1000) is manufactured from the below-mentioned 1st sheet | seat (1a) and 2nd sheet | seat (2a).
[About the first sheet (1a) and the second sheet (2a)]
* First sheet (1a) *
The first sheet (1a) is made of paper and is formed in a rectangular shape as shown in FIGS. The first sheet (1a) has a configuration in which a plurality of first member equivalent portions (10a) corresponding to the first member (10) are integrally continuous to form a rectangular shape as a whole. On each side of the sheet (1a), edge portions (12), (13), (14) and (15) having a constant width extending in a straight line are formed. The first member equivalent portion (10a) is formed such that a portion corresponding to the front side of the first member (10) and a portion corresponding to the back side of the first member (10) are aligned in the width direction. . Information (11) is printed on the back surface of each of the first member equivalent portions (10a). The information (11) may be details such as the amount to be charged to the addressee of the postcard (1000), direct mail guidance, or the like.

* Second sheet (2a) *
The second sheet (2a) is a film (thickness: for example, about 20 μm) made of a transparent synthetic resin (for example, polypropylene resin or polyester resin), and its width is the edge of the first sheet (1a) ( 12) It is set to be substantially the same as the length of (13). As shown in FIG. 3, a first hot melt adhesive (21) is applied to one surface of the second sheet (2a), and a second hot melt is applied to the other surface of the second sheet (2a). A melt adhesive (22) is applied. The second sheet (2a), the first hot melt adhesive (21), and the second hot melt adhesive (22) constitute a film material (2).

  Both the first hot melt adhesive (21) and the second hot melt adhesive (22) are transparent resins mainly composed of ethylene vinyl acetate resin. The amount of resin per unit area of the second hot melt adhesive (22) is set to be significantly smaller than the amount of resin per unit area of the first hot melt adhesive (21). Thereby, the adhesive force of the second hot melt adhesive (22) is significantly smaller than the adhesive force of the first hot melt adhesive (21).

As a method for applying the hot melt adhesive, for example, the resin pellets are heated and melted, and the resin in this state is applied to one surface of the second sheet (2a) by a T-die coater or the like. A method of applying along the longitudinal direction can be adopted. You may employ | adopt the other coating method of this coating method.
[About production of postcard (1000)]
Next, a process for producing a postcard (1000) from the first sheet (1a) and the second sheet (2a) will be described.

  First, a plurality of first sheets (1a) and a second sheet (2a) are prepared. As preparation for the second sheet (2a), the first hot melt adhesive (21) and the second hot melt adhesive (22) are applied to the second sheet (2a) before being set in the laminating apparatus described later. Alternatively, the second sheet (2a) may be prepared by previously applying the first hot melt adhesive (21) and the second hot melt adhesive (22).

  Thereafter, each of the first sheet (1a) and the second sheet (2a) are set in a laminating apparatus shown in FIG. At this time, each of the first sheets (1a) is set on a sheet feeding device (5a) provided in the laminating apparatus and extending in the horizontal direction. Specifically, each of the first sheets (1a) is set so that the edge portions (12) and (13) are overlapped so that the back surface thereof becomes the upper surface and is continuous in a strip shape. This is because the end edges (12) and (13) face each other, there is a gap between them, and the second hot melt adhesive (22) adheres to the roller (4a) to be described later at the time of lamination described later. It is because it is easy to become.

The second sheet (2a) is wound and held in a roll shape above each of the first sheets (1a).
This step corresponds to the “preparation step” described in claims 1 and 2.
Each of the first sheets (1a) is transported by the paper feeding device (5a), and the second sheet (2a) is pulled out from the holding portion and guided downward by the guide rollers (3a) (3b). Is done. Each of the first sheet (1a) and the second sheet (2a) are supplied between a pair of rollers (4a) and (4b) arranged in an opposing state, and these rollers (4a) and (4b) The first sheet (1a) and the second sheet (2a) are pressed. Each of the first sheets (1a) may be manually supplied between the rollers (4a) and (4b).

Further, the upper roller (4b) of the rollers (4a) and (4b) is heated to a predetermined temperature (for example, 100 to 120 ° C.) by a heating device (not shown). The lower roller (4a) is maintained at about room temperature. The surfaces of the rollers (4a) and (4b) are formed in an extremely smooth mirror surface.
Therefore, as shown in FIG. 6, the first sheet (1a) and the second sheet (2a) are heated by the roller (4b) while being pressed by the rollers (4a) and (4b). Since the first hot melt adhesive (21) is in a molten state by this heating, the first sheet (1a) and the second sheet (2a) are bonded.

  At this time, the second hot melt adhesive (22) is also melted and part of the second hot melt adhesive (22) is peeled off from the second sheet (2a) and adheres to the roller (4b). Since the amount of resin per unit area is set to be significantly smaller than the amount of resin per unit area of the first hot melt adhesive (21), a part of the second hot melt adhesive (22) is the second. The degree of peeling off from the sheet (2a) and adhering to the roller (4b) is kept to a minimum.

This step corresponds to the “first bonding step” described in claim 1.
Thereafter, each of the bonded first sheet 1a and the second sheet 2a is cut into a predetermined size by a cutting device 5 as shown in FIG. In this cutting, first, the second sheet (2a) is cut by a blade that enters between the edge portions (12) and (13) overlapped with each other on the first sheet (1a). In this state, the second sheet (2a) is bonded to the range indicated by the two-dot chain line in FIG. 5 in the first sheet (1a). Next, the first sheet (1a) and the second sheet (2a) are cut at the position of the one-dot chain line in FIGS. 4 and 5, the first member equivalent part (10a) is separated from each other, and the edge part (12 ) (13) (14) (15) are removed. Accordingly, the first sheet (1a) (first member equivalent portion (10a)) becomes a plurality of first members (10), and the second sheet (2a) becomes a plurality of second members (20). This step corresponds to the “cutting step” described in claim 1.

  After that, each of the sheet pieces (100) made of the first member (10) and the second member (20) formed by the cutting is in the state shown in FIG. Each is folded in two by a folding device (not shown) so that the dotted line in FIGS. 4 and 5 is a folding line and the second member (20) is inside the first member (10). To be. As a result, the second hot melt adhesive (22) applied to the inner surface of the second member (20) comes into contact with each other.

  Further, as shown in FIG. 8, the sheet piece (100) is heated while being pressed by a pair of opposed heating plates (7a) (7b) provided in a welding device (not shown). By this heating, the second hot melt adhesive (22) is melted and the inner surfaces of the second member (20) are bonded to each other. As a result, the sheet piece (100) becomes the postcard (1000). This step corresponds to the “second bonding step” described in claim 1.

In this postcard (1000), the adhesive force between the inner surfaces of the second member (20) via the second hot melt adhesive (22) is the first member (10) via the first hot melt adhesive (21). ) And the second member (20), it is weaker than the adhesive force between the second member (20) and the second member ( The inner surfaces of 20) peel off.
In this state, since the second hot melt adhesive (22), the second sheet (2a), and the first hot melt adhesive (21) are transparent, the back surface of the first member (10) passes through them. You can see the information (11) printed on. As described above, when the first sheet (1a) and the second sheet (2a) are clamped by the rollers (4a) and (4b), a part of the second hot melt adhesive (22) becomes the second sheet ( Since the degree of adhesion to the roller (4b) after being peeled off from 2a) is suppressed, the surface roughness of the second hot melt adhesive (22) is suppressed and the postcard (1000) is opened to open the second hot melt. The information (11) of the first sheet (1a) can be clearly seen with the adhesive (22) peeled off.

In this case, since the adhesive applied to the second sheet (2a) is the first hot melt adhesive (21) and the second hot melt adhesive (22), it can be left as it is. it can. Therefore, the laminating apparatus does not require a conventional apparatus for applying and drying an ordinary adhesive, and the laminating apparatus is downsized.
Therefore, for laminating the first sheet (1a) and the second sheet (2a), a desktop laminating apparatus generally installed in an office or the like can be used.
