Next, as shown in FIG. 4, the laminate obtained by winding the base material 18 on which the concealing layer 20 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 unwound and guided to the resin coating device 34 . This resin coating device 34 is for printing and coating a resin 22a such as the vinyl chloride-vinyl acetate copolymer described above on the surface of the hidden layer 20 of the base material 18.

The base material 18 printed and coated with the resin 22a is then led to a dryer 36, where the resin 22a is dried and formed as the primer layer 22.

Next, the base material 18 on which the primer layer 22 has been formed is led to a thermal adhesive resin coating device 40 for printing and applying a thermal adhesive resin 24a whose main ingredient is, for example, the above-mentioned ethylene-vinyl acetate copolymer resin. It will be destroyed.

The thermal adhesive resin coating device 40 is a printing/coating device that utilizes a known printing/coating method such as letterpress printing, gravure printing, or silk screen printing.

This thermal adhesive resin coating device 40 coats the primer layer 2.
A thermoadhesive resin 24a is printed and coated on the surface of 2.

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 pressing roller 162 presses the surface of the coating material 14 while rotating.

Then, the adhesive portion transfer table 118 and the pressurizing/heating device 150 are formed again at the tip position of the covering material 14 sent later in the next cycle after the process of cutting the continuous body 14a of the covering material 14a. The linear pressure and heating device 152 and the planar pressure and heating device 154 are joined. At this time, the coating material 14 sent in the previous cycle is transferred to the sheet pressure heating device 15.
It is located at the bottom of 4. Then, the continuous postcard base paper 10a to which the leading edge of the covering material 14 of the next cycle is adhered is transported a certain distance by the operation of the continuous paper transport device 102, and the previous covering material 14 that was previously sent in the previous cycle is transported by the continuous paper transport device 102. The material 14 is pressed and heated by the planar pressing and heating device 154.

That is, when the covering material 14 whose tip is bonded is located at the lower part (initial upstream position) of the planar pressure and heating device 154, the planar pressure and heating device 154 moves to the bonded portion transfer table. 118 surface by the action of the cam groove formed in the disc 172, and pressurizes and heats the covering material 14.

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.

In the covering material 14 adhered in this manner, the thermoadhesive resin layer 24 is strongly adhered to the base material 18 or the hiding layer 20 and weakly adhered to the postcard mount 12. Therefore, as shown in FIGS. 12A and 12B, the covering material 14 can be cut at the cuts 26a and 26b and peeled off from the postcard mount 12 relatively easily. In this case, the entire covering material 14 can be easily peeled off from the postcard mount 12, not just the portion sandwiched between the cuts 26a and 26b. The surface of the postcard mount 12 can then be seen.

Furthermore, between the cuts 26b and 26C, the base material 18. Hidden layer 20. At one end of the primer layer 22 and the thermoadhesive resin layer 24, a notch 27 having, for example, a planar semicircular shape is formed.

Therefore, in this embodiment, when the vertical center portion of the covering material 14 is peeled off, the narrow portion between the cuts 26b and 26C is first peeled off, as shown in FIGS. 14A and 14B. In this case, by placing a finger on the notch 27, the narrow portion between the notches 26b and 260 can be easily peeled off. Then, the surface of the postcard mount 12 can be seen by bending or cutting the vertical center portion of the covering material 14 along the cut 26a.

In the embodiment shown in FIGS. 13A and 13B, instead of forming the notch 27, a projecting piece extending outward may be formed between the cuts 26b and 26c. In this way, by pinching the protrusion, the narrow portion of the covering material 14 can be peeled off more easily.

In each of the above-mentioned embodiments, the vertical center portion of the covering knife 4 is peeled off first, but for example, the base material 18. Hiding layer 20° is configured such that a cut is formed along the periphery of the primer layer 22 and the thermoadhesive resin layer 24, and the covering material 14 can be peeled off from the postcard mount 12 by first cutting the center portion along the cut. You can.
