  Next, when the adherend WK is conveyed to a predetermined position below the holding member 31 by the conveying means CV, the adherend WK is detected by a detection means such as an optical sensor or an imaging means (not shown), and is conveyed by the conveying means CV. The conveyance of the adherend WK is stopped. Thereafter, the feeding means 10 drives the rotation motor 13 to feed the original fabric RS. Then, as shown in FIG. 2 (A), the leading end AS1 in the feeding direction of the adhesive sheet AS passes a predetermined amount through the bent edge 21, and the detecting means 18 detects the end on the upstream side in the feeding direction of the adhesive sheet AS. Then, the feeding means 10 stops driving the rotation motor 13.

  Next, the pressing means 30 drives the linear motor 32 to raise the holding member 31 to the sheet receiving position indicated by the solid line in FIG. At this time, even when the leading end portion AS1 in the feeding direction of the adhesive sheet AS is folded back at the bent end edge 21 together with the bent portion RL1 of the release sheet RL bent by the peeling means 20, a two-dot chain line in FIG. As shown, the abutting member 40A is raised while abutting on the leading end portion AS1 in the feeding direction of the adhesive sheet AS, so that the leading end portion AS1 is raised from the release sheet RL and peeled off, and the leading end portion AS1 is peeled off. Part AS2 is formed. Further, when the holding member 31 is raised to the position indicated by the two-dot chain line in FIG. 2B, the adhesion preventing means 50 drives a gas supply device (not shown) from the upper side toward the leading end portion AS1 of the adhesive sheet AS. By blowing the gas, the tip portion AS1 is bonded to the contact member 40A, and the adhesive sheet AS is prevented from being lifted and peeled off from the release sheet RL.

Next, the feeding means 10 drives the rotation motor 13 again and feeds the original fabric RS by a predetermined amount. Further, the pressing means 30 drives the suction means 34 to adsorb and hold the peeled adhesive sheet AS on the lower surface of the holding member 31. Then, the pressing means 30 drives the linear motor 32 to lower the holding member 31 and presses and adheres the adhesive sheet AS held by the holding member 31 to the adherend WK.
When the adhesive sheet AS is attached to the adherend WK as described above, after the pressing unit 30 stops the suction unit 34, the pressing unit 30 drives the linear motor 32, and the holding member 31 is moved to FIG. A) Raise to the position indicated by the solid line. Thereafter, the conveying means CV is driven to convey the adherend WK to which the adhesive sheet AS is adhered to another process, and thereafter the same operation as described above is repeated.

According to this embodiment as described above, the following effects are obtained.
That is, since the peeling trigger portion AS2 is formed at the leading end portion AS1 in the feeding direction of the adhesive sheet AS, the peeling trigger portion AS2 promotes the peeling of the adhesive sheet AS, and the adhesive sheet AS is reliably peeled from the release sheet RL. The adhesive sheet AS can be reliably attached to the adherend WK.
