切断や溝加工ができる。As described above, the end of the sheet 2 protruding from the substrate 1 in the direction of movement of the substrate 1 is guided downward from the tip surface 3 side of the substrate 1 by the suction device 4, and the end of the sheet 2 guided downward is rolled into the fixture. 6, the sheet 2 is rolled up along the front end surface 3 and back surface 5 of the substrate 1, so the end of the sheet 2 rolled up on the back surface 5 side of the substrate 1 is attached to the tip of the substrate 1 due to the adhesive applied to the back surface of the sheet 2. Since the sheet 2 is adhered to the surface 3 and the back surface 5, it will not peel off from the substrate 1, so even if the substrate 1 is post-processed immediately after laminating the sheet 2 on the substrate 1 using a semi-dry or wet method, the adhesive will remain on the sheet. Even if the sheet 2 is laminated onto the substrate 1 by a wet method, the sheet 2 can be cut and grooved continuously after the lamination process.
