Then, the sticking means 20 drives the rotation motor 25A to feed out the original fabric RS, and as shown by the solid line in FIG. 1 (A), the leading end portion of the leading adhesive sheet AS in the feeding direction is the peeling edge 23A of the peeling plate 23. When a predetermined amount is peeled off, the driving of the rotation motor 25A is stopped.

  Next, the user or an unillustrated conveyance means such as an articulated robot or a belt conveyor places the adherend WK at a predetermined position on the inner table 13 and the ring frame RF at a predetermined position on the outer table 12. When is mounted, the supporting means 10 drives the depressurizing means (not shown) to start sucking and holding the adherend WK and the ring frame RF on the supporting surfaces 13A and 12A. After that, the substitute member supply means 40 drives the linear motor 41, and the ring frame RF and the adherend are adhered to each other as shown by the two-dot chain line on the right side in FIG. 1A and the reference numeral AA in FIG. The substitute member SS is supplied above WK, and the driving of the linear motor 41 is stopped. Then, the supporting means 10 drives the linear motor 11 to move the outer table 12 to the left, and when the outer table 12 reaches a predetermined position, the attaching means 20 drives the rotation motor 25A and the outer table 12 is moved. The original fabric RS is paid out according to the moving speed of. As a result, the adhesive sheet AS is peeled off from the release sheet RL by the release plate 23, and is pressed and adhered to the adherend WK and the ring frame RF by the pressing roller 24, so that the adherend WK passes through the adhesive sheet AS.

Then, the substitute member SS is supplied to the substitute member SS, and the unattached portion of the adhesive sheet AS is attached to the substitute member SS, as indicated by the chain double-dashed line in FIG. After that, the outer table 12 and the chuck cylinder 43 continue to move to the left, the adhesive sheet AS is affixed to the substitute member SS and the ring frame RF, and the leading end portion of the next adhesive sheet AS following the leading end is peeled off. When a predetermined amount is peeled off at the peeling edge 23A of the plate 23, the sticking means 20 stops driving the rotation motor 25A. After that, when the outer table 12 and the chuck cylinder 43 reach a predetermined position on the left side of the pressing roller 24, the supporting means 10 and the substitute member supplying means 40 stop driving the linear motors 11 and 41, and then the supporting means 10 is illustrated. The drive of the pressure reducing means is stopped, and the suction holding of the adherend WK and the ring frame RF on the support surfaces 13A, 12A is released. Next, the substitute member supply unit 40 drives the chuck cylinder 43 to release the grip of the substitute member SS, and the user or a transport unit (not shown) conveys the ring frame RF integrated with the substitute member SS via the adhesive sheet AS. When the adherend WF is removed from the outer table 12 and the adherend WF is removed from the inner table 13, the supporting means 10 and the substitute member supplying means 40 drive the linear motors 11 and 41 to move the outer table 12 and the chuck cylinder 43. Return to the initial position. Then, when the substitute member supply means 40 drives the chuck cylinder 43 and grips the substitute member SS conveyed by the user or the conveying means (not shown), the same operation as described above is repeated.
