<p>The disclosed separation method and separation device can continuously and stably separate a low-release-strength film from a film laminate such that an adhesive layer does not remain on the low-release-strength film. Tension control is performed as follows: the tension of a conveyed low-release-strength film (31) is kept constant by adjusting the rotation speed of a nip roller forming a second nip unit (2), and the tension of a conveyed high-release-strength film (32) is kept constant by adjusting the rotation speed of a nip roller forming a third nip unit (3). A film laminate (30) is continually outputted from a first nip unit (1), and the low-release-strength film (31) and the high-release-strength film (32) are continually conveyed at the abovementioned tension. As a result, the low-release-strength film (31) is continuously and stably separated from the film laminate (30) at a separation roller (4).</p> |
