In the sheet sticking apparatus 1 described above, as a procedure for sticking the adhesive sheet S to the adherend W, first, as shown in FIG. 1, the first original fabric R1 is attached to the guide roller 212, the first peeling plate 4, and the first. The second bypass rollers 71 and 72, the re-attachment plate 8, and the guide rollers 221 and 222 are sandwiched between the drive roller 224 and the pinch roller 225 and set on the recovery roller 226. At this time, the adhesive sheet S located on the downstream side in the feed-out direction of the first original fabric R1 than the printing unit 3 is removed.
In this state, the rotation motors 223, 521, 63, and 64 are synchronously driven to feed the first original fabric R1 from the support roller 211 toward the collection roller 226. The adhesive sheet S temporarily attached to the fed first original fabric R1 is subjected to predetermined printing by the printing means 3. With respect to this printing, in each of the printing means exemplified in the printing means 3, if the distance to the surface of the adhesive sheet S that is the printing object is not accurately maintained, the contents of printing or printing may be rubbed or blurred. Therefore, accurate and clean printing cannot be performed. That is, since the surface of the adhesive sheet S on which the first and second concave grooves M1 and M2 are formed has an uneven shape due to these grooves, the distance between the printing means 3 and the surface of the adhesive sheet S is irregular. Therefore, accurate and clean printing cannot be performed. In that respect, since the sheet sticking apparatus 1 of the present invention is configured to perform printing before forming the first and second concave grooves M1 and M2, accurate and clean printing can be performed.
As for the 1st original fabric R1 to which printing was performed, the adhesive sheet S is peeled from the peeling sheet RL when the peeling sheet RL is folded back by the first peeling plate 4. Then, the release sheet RL is guided to the re-tacking plate 8 so as to bypass the groove forming means 6 by the bypass means 7.
On the other hand, the adhesive sheet S is sequentially delivered from the front end in the feeding direction to the conveying means 5 at the same time as being peeled from the release sheet RL.

The adhesive sheet S delivered to the conveying means 5 is supported by suction of the suction chamber 54 via the endless belt 53, and is conveyed leftward by the rotation of the endless belt 53.
Next, the adhesive sheet S conveyed by the conveying means 5 is first in a state where the adhesive layer AD is softened by the softening means 61 and the first and second concave grooves M1 and M2 are easily formed. Then, the adhesive sheet S is further conveyed and is sandwiched between the support surface 541 and the rotating first transfer body 64 via the endless belt 53. As a result, the first convex portion 641 of the first transfer body 64 is pressed against the softened adhesive layer AD, and the first concave groove M1 is formed in the adhesive layer AD as shown in FIG. Subsequently, the adhesive sheet S is sandwiched between the support surface 541 and the second transfer body 65, and the second convex portion 651 is pressed against the adhesive layer AD, whereby the second concave groove M2 is formed. Thus, the adhesive layer AD in which the first and second concave grooves M1 and M2 are formed is cured by the curing means 66, and the first and second concave grooves M1 and M2 are not easily deformed. In addition, the 1st, 2nd ditch | groove M1, M2 continues to either one edge of the adhesive sheet S, respectively, and is open at the edge.
Thereafter, the adhesive sheet S is guided onto the re-tacking plate 8 and reaches the front side of the pulley 52, so that the suction force by the suction chamber 54 does not work and is sequentially transferred onto the release sheet RL. The adhesive sheet S in which the second concave grooves M1 and M2 are formed is temporarily attached to the release sheet RL to form a second original fabric R2.

  Thereafter, the adhesive sheet S printed first is peeled off at the leading edge side by the second peeling plate 10, and the leading edge is detected by an adhesive sheet detection sensor (not shown) to rotate the motors 223, 521. The driving of 63 and 64 is stopped and a standby state is entered. Then, when the adherend W is conveyed leftward by the adherend conveying means 12, the adherend detection sensor (not shown) indicates that the upper surface of the adherend W is located at a predetermined position below the pressing roller 11. , The driving of the rotation motors 223, 521, 63, 64 is restarted, and the adhesive sheet S, which has been peeled off at the leading edge side by the second peeling plate 10, is peeled again from the peeling sheet RL. Then, the adherend conveying means 12 moves the adherend W to the left in FIG. 1 and presses the adhesive sheet S against the adherend W by the pressing roller 11, whereby the adhesive sheet S is attached to the adherend W. Affix to the upper surface by pressing.

  Moreover, in the sheet sticking apparatus 1 as described above, the distance between the first release plate 4 and the re-temporarily attaching plate 8 can be changed by moving the output shaft 92 forward and backward by the linear motor 93. For example, when the first and second transfer members 64 and 65 are replaced, the replacement operation is facilitated by increasing the distance between the first release plate 4 and the re-temporary attachment plate 8. In addition, the distance between the first release plate 4 and the re-temporary attachment plate 8 can be appropriately adjusted according to the number and size of the transfer members.

According to the embodiment as described above, the process from the step of forming the concave groove on the adhesive sheet S to the step of applying the adhesive sheet S to the adherend W is continuously performed. Without causing deformation of the first and second concave grooves M1 and M2 due to the influence of the winding pressure and the like, the first and second concave grooves M1 and M2 ensure that the adhesive sheet S and the adherend W are separated.
