In the sheet sticking apparatus 1 described above, a procedure for sticking the adhesive sheet AS to the adherend WK will be described.
First, the raw fabric RS is set as shown in FIG. 1, and the right end portion of the holding member 31 is positioned in the retreating portion 23 of the peeling plate 22 (see FIG. 2A) in plan view, and the holding surface 31A is The holding member 31 is made to stand by in a state positioned below the adhesive sheet AS. Next, when the adherend WK transported by the transport means CV is detected by a detection means such as an imaging means or a sensor (not shown), the adherend WK stops at a predetermined position above the holding member 31. Next, the feeding means 10 drives the rotation motor 13 to feed out the original fabric RS by a predetermined amount, applies tension to the release sheet RL, and bends the release sheet RL along the retracted portion 23. As a result, as shown in FIG. 2A, both the front and rear end portions of the adhesive sheet AS are temporarily attached to the release sheet RL, while the central portion of the adhesive sheet AS positioned at the retreating portion 23 is separated from the release sheet RL. It will be in the peeled state. Then, after the pressing means 30 drives the linear motion motor 32 to raise the holding member 31 and bring the holding member 31 into contact with the first pseudo adhesive layer AP1, the suction means 34 is driven, and the holding surface 31A The central portion of the adhesive sheet AS is sucked and held.

Thereafter, the pressing means 30 drives the linear motion motor 32 and, as shown by a two-dot chain line in FIG. 1, presses and adheres the adhesive sheet AS to the lower surface of the adherend WK, and then the suction means 34 is driven. While stopping, the linear motor 33 is driven to move the pair of holding members 31 in directions away from each other as shown in FIG. As a result, it is possible to apply a pressing force to the entire adhesive sheet AS and reliably adhere the adhesive sheet AS to the adherend WK.
When the adhesive sheet AS is attached to the adherend WK as described above, the pressing unit 30 drives the linear motor 33 to move the pair of holding members 31 in the direction in which the pair of holding members 31 come into contact with each other. 32 is driven, and the holding member 31 is lowered to the position shown by the solid line in FIG. 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 adhesive sheet AS is partially peeled from the release sheet RL and the partially peeled position is held by the holding member 31, the adhesive sheet AS can be reliably delivered to the pressing means 30, and the adhesive sheet It is possible to prevent the AS from falling across the pressing means 30 and to be taken up together with the release sheet RL without being peeled off by the peeling means 20, and to prevent the adhesive sheet AS from being stuck to the adherend WK. can do.
