In the sheet sticking apparatus 1 described above, a procedure for sticking the adhesive sheet AS to the adherend WK will be described.
First, as shown by the solid line in FIG. 1, in the state where the separation distance between the peeling edge 32A and the right side surface of the holding plate 62 is the sticking preparation distance LB, for example, 150 mm, the joint is not manually shown by the operator As shown in FIG. 1, the raw fabric RS supported by the support roller 22 is wound around the rollers 31, 34, 35 and the release plate 32 by driving the robot, and the leading end of the release sheet RL is supported by the collection roller 42. (Hereinafter referred to as “raw material wrapping operation”).

  Thereafter, when the operator inputs an operation start signal via an operation panel or the like (not shown), the moving means drives the linear motor 7 and moves the supply means 3 in the left direction. At this time, the support means 2, the supply means 3 and the recovery means 4 drive the motors 21, 33, 41 to feed out the original fabric RS and the release sheet RL in the feeding directions DA and DB. The anti-RS is prevented from extending and plastically deforming or cutting.

Next, the frame 30 reaches the position indicated by the two-dot chain line in FIG. 1, and the separation distance between the peeling edge 32A of the peeling plate 32 and the right side surface of the holding plate 62 of the pressing means 6 is a supplyable distance LA, for example, 0.

Move to the right. At this time, the support means 2, the supply means 3 and the recovery means 4 drive the motors 21, 33, 41 to rotate in the winding direction of the original fabric RS and the release sheet RL. Prevents anti-RS from sagging. Next, when a detection means such as a sensor or a camera (not shown) detects that the separation distance between the peeling edge 32A of the peeling plate 32 and the right side surface of the holding plate 62 of the pressing means 6 has become the pasting preparation distance LB, The means stops the driving of the linear motor 7, and the supporting means 2, the supplying means 3 and the collecting means 4 stop the driving of the motors 21, 33 and 41. Then, the original fabric RS is removed from the support means 2, the supply means 3, and the collection means 4 by an operator manually or by driving an articulated robot (not shown) as a drive device. After that, the above-described original web wrapping operation is performed, and thereafter the same operation is repeated.

  According to the embodiment as described above, since the original fabric RS can be wound around the peeling plate 32 in a state in which the separation distance between the peeling plate 32 and the pressing means 6 is longer than the supplyable distance LA, the peeling plate 32 is provided.
