<P>PROBLEM TO BE SOLVED: To optionally set the position of a sealing domain or an unsealing cut against a tubular film according to a change in the size of the tubular film in a width direction. <P>SOLUTION: An end sealing device applies an end seal on the tubular film in a width direction Y which intersects with a transporting direction X of the tubular film which is sandwiched between seal surfaces that face each other at a fitting position of a pair of seal bodies. The seal body is installed on sealer frames that are supported by movable frames 5. When an operation handle 9a is operated, sliders 8, 2 provided on the movable frames 5 can be moved in the width direction Y of the tubular film together with the seal bodies on both sealer frames along slide guides 3, 6 installed on a fixed frame 1 by a spring mechanism. Thus both seal bodies on a top and a bottom move in the width direction Y with respect to the transportation center P of the tubular film that is transported from the upstream side and the positional relationship between the tubular film and the seal surfaces changes. <P>COPYRIGHT: (C)2009,JPO&INPIT |
