Abstract
There is provided a packaging apparatus including a mechanism for joining a film from a film roll and a film from another film roll to each other. The packaging apparatus is capable of preventing a joint of the films from suffering a thermal sealing failure thereby increasing production efficiency. Package apparatus () includes film supply mechanism (A) for joining and supplying films (A,B) and packaging mechanism (C) for producing package bags from the film. Film accumulator (B) for guiding and holding the film in a meandering fashion is disposed between film supply mechanism (A) and packaging mechanism (C). Some of accumulating rollers () of film accumulator (B) are movable to a predetermined position depending on the size of package bags to be manufactured. The length of the film from a position in which the films are joined to each other to a position in which the film is horizontally sealed is changed to prevent the joint between the films from being placed in the position in which the film is horizontally sealed.
