Abstract

필름을 통형상으로 성형한 필름 포장체를 제조할 때에, 필름 용착부에 있어서의 용융 상태가 가장 좋게 되도록 조정할 수 있게 한다.
성형 부재에 의하여 통형상으로 성형된 필름(1)은 고주파 전극(10)(11)에 끼워져 용착되며, 용착선(2)이 형성된다. 상기 전극(10)(11)바로 아래에 상부 사이즈 링(21a)등 보다도 직경이 약간 큰 확장 링(23a)을 배치하여 놓는다. 연속적으로 성형되어 확장 링(23a)을 통과하여 가는 용착선(2)을 눈으로 관찰하면서 전극(10)(11)에 공급하는 고주파 전력을 서서히 중강하여 간다. 공급 전력이 높아지면, 용착선(2)의 용융이 과잉으로 되고 확장 링(23a)의확장력을 받아서 용착선(2)이 좌우로 나누어지겨 간다. 이 나누어짐이 발생하기 직전에 고주파 전력을 고정하므로서 가장 좋은 용융 상태의 용착선(2)을 형성할 수 있게 된다.
