At the same time, the linear pressurizing and heating device 152 and the planar pressurizing and heating device 154 move together with the bonding portion transfer table 118 in the direction opposite to the flow of the continuous postcard 10a, that is, to the original upstream predetermined position. I do. At this time, the pressing roller 162 presses the surface of the coating material 14 while rotating.

Then, again, at the front end position of the coating material 14 that has been sent later in the next cycle through a process such as cutting the continuous body 14a of the coating material, the bonding unit transfer table 118 and the pressure heating device 150 are formed. Linear pressure heating device 152 and planar pressure heating device 1
Joins with 54. At this time, the coating material 14 fed in the previous cycle is located below the planar pressure heating device 154. Then, the postcard continuous base paper 10a to which the leading end of the coating material 14 of the next cycle is adhered is transported by a certain distance by the operation of the continuous paper transporting device 102, and the previous coating paper that has been previously sent in the previous cycle. The material 14 is pressed and heated by the planar pressure heating device 154.

That is, when the coating material 14 to which the tip is bonded is located below the planar pressure heating device 154 (the initial upstream position), the planar pressure heating device 154 118
It is pressed against the surface by the action of the cam groove formed in the disk 172, and the coating material 14 is heated under pressure.

Note that the transfer distance of the postcard continuous base paper 10a is also regulated by the pulse generated by the encoder formed in the continuous paper transfer device 102, and the central processing unit 176 controls the coating material transfer device 120, the coating material cutting device 126 and The transfer of the pressurizing and heating device 150 is controlled.
However, the postcard continuous base paper 10a is formed so as not to move backward, and runs backward in accordance with the backward movement of the linear pressure heating device 152 and the sheet pressure heating device 154 of the bonding portion transfer table 118 and the pressure heating device 150. It is formed not to be done.

As described above, the pressurizing and heating device 150 repeats the cycle of the forward movement, the thought point (downstream side), the reverse movement, and the thought point (upstream side) to form the postcard backing sheet which forms the continuous paper 10 as shown in FIG.
The covering material 14 is appropriately adhered to the surface of the substrate 12.

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

The coating material 14 thus bonded is strongly bonded at the portion where the second thermo-adhesive resin layer 26 is formed,
The portion where the second heat-adhesive resin layer 26 is not formed is weakly bonded. Accordingly, FIGS. 12A and 12B
As shown in the figure, in the portion where the second heat-adhesive resin layer 26 is not formed, the base material 18, the hiding layer 20, the primer layer 22
In addition, the first heat-adhesive resin layer 24 can be cut off at the cuts 28a and 28b and can be relatively easily peeled off from the postcard mount 12. In this case, even in a portion where the second heat-adhesive resin layer 26 is formed in a spot shape, the base material 18, the concealing layer 20, the primer layer 22
In addition, the first heat-adhesive resin layer 24 can be easily peeled off. And it can be seen on the surface of the postcard mount 12.

13A and 13B show another embodiment of the present invention, respectively, wherein FIG. 13A is a perspective view thereof, and FIG. 13B is a sectional view thereof. In this embodiment, another cut 28c is formed in the base material 18, the concealing layer 20, the primer layer 22, and the first heat-adhesive resin layer 24, slightly inside the cut 28b. The cut 28c is formed together with the cuts 28a and 28b by, for example, a die roll. In addition, cut 28b
Between the base material 18, the concealing layer 20, the primer layer 22, and one end of the first heat-adhesive resin layer 24, a notch 29 having, for example, a plane semicircular shape is formed between the base material 18, the concealing layer 20, the first heat-adhesive resin layer 24.

Therefore, in this embodiment, when peeling the central portion in the vertical direction of the covering material 14, as shown in FIGS. 14A and 14B,
First, the base material 18, the concealing layer 20, the primer layer 22, and the first heat-adhesive resin layer 24 are peeled off at the narrow portion between the cuts 28b and 28c. In this case, if you put your finger on the notch 29,
The base material 18, the hiding layer 20, the primer layer 22, and the first heat-adhesive resin layer 24 can be easily peeled off at the narrow portion between b and 28c. Then, if the center portion of the covering material 14 in the vertical direction is bent at the cut 28a or cut at the cut 28a, the postcard
You can see 12 surfaces.

Note that, in the embodiment shown in FIGS. 13A and 13B,
Instead of forming the cutout 29, a protruding piece extending outward between the cuts 28b and 28c may be formed. By doing so, the narrow portion of the covering material 14 can be more easily removed by pinching the protruding piece.

In each of the above-described embodiments, each of the covering members 14 is configured so that a central portion in the vertical direction can be peeled off. For example, a second heat-adhesive resin layer 26 is formed around the covering member 14, Further, the base material is formed along the edge of the second heat-adhesive resin layer 26.
18, a notch is formed in the concealing layer 20, the primer layer 22, and the first heat-adhesive resin layer 24, and the center portion of the covering material 14 is cut at the notch so that it can be peeled off from the postcard mount 12. You may.
