PACKAGING DEVICE

摘要

A packaging device having a mechanism for bonding together a film from one material film roll and a film from the other material film roll, wherein a failure in heat sealing at a portion where the film are bonded is prevented to enhance production efficiency. The packaging device (10) has a film supply mechanism (10A) for supplying the films (1A, 1B) after bonding them and a packaging mechanism (10C) for forming the films into a bag. A film storage section (10B) for guiding and holding the films in a meandering manner is provided between the film supply mechanism (10A) and the packaging mechanism (10C). Some accumulating rollers (21) of the film storage mechanism (10B) are adapted to move to predetermined positions according to the size of a packaging bag to be produced. The length of the films from a position at which the films are bonded together to a position at which lateral sealing is applied to the films is changed, so that the bonding position of the films does not come to the lateral sealing position.
