Note that the second thermoadhesive resin N24 may be formed on the surface of the first thermoadhesive resin layer 22 only at both upper and lower ends or at both left and right ends of the covering material 14. In this case, the second thermoadhesive resin layer 24 may be formed with a constant width or may be formed in a spot shape.

Subsequently, a method for manufacturing the covering material 14 will be explained.

Next, as shown in FIG. 4, the laminate obtained by winding the base material 18 on which the concealing N20 is formed into a roll is loaded onto the holding roller 32 of the coating material manufacturing apparatus 30.

One end of the base material 18 held by the holding roller 32 is unraveled, and the base material 18 is used for printing and applying, for example, the above-described thermoadhesive resin 22a, which has a weak adhesive strength and is mainly composed of ethylene-vinyl acetate copolymer resin. The heat-adhesive resin coating device 34 is guided thereto. The thermal adhesive resin coating device 34 is a printing/coating device that utilizes a known printing/coating method such as letterpress printing, gravure printing, or silk screen printing.

By this thermal adhesive resin coating device 34, the hiding layer 20
A thermoadhesive resin 22a having a weak adhesive force is printed and applied on the surface of the .

Then, the base material 18 printed and coated with the thermal adhesive resin 22a is led to a dryer 36, where the thermal adhesive resin 22a is applied.
2a is dried and formed as a first thermoadhesive resin N22.

Next, the base material 18 on which the first thermoadhesive resin layer 22 is formed
is guided to a thermoadhesive resin application device 40 for printing and applying a thermoadhesive resin 24a having strong adhesive strength. The thermal adhesive resin coating device 40 is a printing/coating device that utilizes known printing/coating methods such as letterpress printing, gravure printing, and silk screen printing. This thermal adhesive resin coating device 40 partially prints and applies a thermal adhesive resin 24a having strong adhesive force on the surface of the first thermal adhesive resin layer 22.

Then, the base material 1 on which the thermoadhesive resin 24a is printed and applied

Next, regarding the operating state of this coating material bonding device, the first
This will be explained with reference to the time chart shown in FIG.

The continuous postcard base paper 10a is transferred by a predetermined amount by the sprocket transfer device 106 of the continuous paper transfer device 102.

In this embodiment, the adhesive portion transfer table 118 moves from the downstream side to the upstream side of the continuous postcard base paper 10a.

On the other hand, the coating material transfer device 120 transfers the coating material continuum 14a from the reel 122, and as a result, the coating material detection device 124 detects a detection mark formed on the surface of the coating material continuum 14a, which is an arrow mark in this embodiment. By detecting this, the transfer of the continuous body 14a of the covering material is also temporarily stopped, and the adhesive portion transfer table 118 is also stopped.

At this time, the covering material cutting device 126 is activated and the cutter 1
30a and 130b adjust the continuous body 14a of the covering material to an appropriate size, that is, -

Note that the transport distance of the continuous postcard base paper 10a is also regulated by pulses generated by an encoder formed in the continuous paper transport device 102, and the central processing unit 176 controls the transporting distance of the continuous postcard paper 10a, the covering material transporting device 120, the covering material cutting device 126, and the central processing unit 176. It is configured to control the transfer of the pressure heating device 150. However, the continuous postcard base paper 10a is formed so as not to move backward, and in response to the backward movement of the adhesive portion transfer table 118, the linear pressure heating device 152 of the pressure heating device 150, and the planar pressure heating device 154, the continuous postcard base paper 10a is It is designed so that it will not be damaged.

In this way, the pressurizing and heating device 150 repeats the cycle of forward movement, consideration point (downstream side), backward movement, consideration point (upstream side), and as shown in FIG. A covering material 14 is appropriately adhered to the surface of.

The continuous paper 10 partially covered with the covering material 14 in this manner is folded as appropriate, then cut off as appropriate, and delivered to a post office.

The thus bonded covering material 4 is strongly bonded in the areas where the second thermoadhesive resin layer 24 is formed, and in the areas where the second thermal adhesive resin layer 24 is not formed. Weakly bonded.

Therefore, as shown in FIGS. 12A and 12B, the base material 18. The cover N20 and the first thermoadhesive resin layer 22 can be cut and peeled off from the postcard mount 12 relatively easily. In this case, even in the portion where the second thermoadhesive resin layer 24 is formed in a spot shape, the base material 18
．． The cover N20 and the first thermoadhesive resin layer 22 can be easily peeled off. The surface of the postcard mount 12 can then be seen.

In addition, when covering confidential information such as bank deposit balances formed on a part of the surface of a postcard, the base material 18 is divided between the part where the second thermoadhesive resin layer 24 is formed and the part where it is not.
．． A cut is made in the base material 18 so that the hiding layer 20 and the first thermoadhesive resin layer 22 can be separated. hidden layer 2
0 and the first thermoadhesive resin layer 22, and the base material 18. Hidden layer 20 and the first
The thermoadhesive resin layer 22 may be formed so that it can be separated from the postcard mount 12.

For example, if the second heat-adhesive resin layer 24 is formed on the peripheral edge of the surface of the first heat-adhesive resin layer 22 and the cut is formed along the periphery of the base material, the central part of the covering material can be You can tear it off. In this case, as shown in FIG. 13, adjacent cuts 2
If one cut 26 is composed of a straight cut portion 27a and an arcuate cut portion 27b so that the cut portions 6 partially overlap, the central portion of the covering material 14 can be easily peeled off. In addition, in order to be able to easily peel off the central part of the covering material in this way, for example, the first
As shown in FIG. 4, linear cuts 26 may be formed diagonally around the base material 18 so that adjacent cuts 26 partially overlap when viewed in the direction in which the coating material 14 is peeled off.
