In this way, the second connecting tape 32 disposed to form a curved surface is unfolded along the rotation of the second attachment roller 160 and attached to the lower surface of the junction of the first film 10 and the second film 20. do. Therefore, it is possible to prevent bubbles and wrinkles from occurring during the attachment process.

제2 부착 롤러(160)는 제1 부착 롤러(150)의 접합 지점(절단 지점)과 다른 지점에서 접합을 수행하도록 마련될 수 있다. 예를 들어, 제2 부착 롤러(160)는 제1 이송부(110)의 롤러(제1 롤러, 111) 측에 배치될 수 있다.The second attachment roller 160 may be provided to perform bonding at a different point from the bonding point (cutting point) of the first attachment roller 150. For example, the second attachment roller 160 may be disposed on the roller (first roller, 111) side of the first transfer unit 110.

따라서, 제어부는 제1 연결 테이프(31)의 접착이 완료되면, 제1 필름(10)과 제2 필름(20)을 제2 부착 롤러(160)가 위치된 지점까지 제1 이송부(110)를 통해 이송시킬 수 있다.Therefore, when the bonding of the first connecting tape 31 is completed, the control unit moves the first film 10 and the second film 20 to the first transfer unit 110 to the point where the second attachment roller 160 is located. Can be transported through.
