- the first clamper 3 moves in the direction of the arrow under the guiding action of the horizontal guide 5a and the vertical guide 5b to peel the film F from the glass substrate 1, and then the film F is moved to the second clamp. Passed to 6. At that time, the peeled film F is spread in the horizontal direction via the film pusher 7, and the films F are stacked and accommodated.
- the film F is given a peeling operation along a linear peeling speed pattern having a bent portion. Therefore, during the film F peeling operation, there are changing points Pl, P2 and P3 in which the speed rapidly changes corresponding to the bent portion. For this reason, at these change points Pl, P2 and P3, the peeled state of the film F changes rapidly and streaks occur on the surface of the photosensitive resin layer. This problem also occurs when the film F is peeled off while keeping the acceleration and / or deceleration constant.

- the gripping mechanism is moved along the velocity pattern or acceleration pattern of the S-curve at the start of peeling of the outer layer body. For this reason, it is possible to prevent the outer layer body from being rapidly peeled off. For example, it is possible to satisfactorily prevent cohesive failure of the photosensitive resin layer and to prevent generation of dust due to breakage as much as possible.
- the speed or acceleration rapidly increases along the S-curve, so that a good peeling work is performed and the efficiency of the peeling work is achieved. Therefore, it is possible to effectively peel the outer layer body that does not cause cohesive failure of the photosensitive resin layer with a simple process and configuration, and to easily perform the efficiency of the peeling work.
