Abstract
A bag packaging apparatus includes a forming mechanism, a pull down belt mechanism, a longitudinal seal mechanism, a latitudinal seal mechanism, and a settling mechanism. The forming mechanism forms films into tubular shape. The pull down belt mechanism conveys the tubular film F. The longitudinal seal mechanism seals the tubular film F in a longitudinal direction. The latitudinal seal mechanism seals the tubular film F in a latitudinal direction. The settling mechanism is disposed between the forming mechanism and the latitudinal seal mechanism, and between the longitudinal mechanism and the latitudinal mechanism. The settling mechanism presses a portion of the tubular film F that is going to become an upper end of a bag and a bottom end of a following bag, while seal jaws seal the tubular film F. The sealed portion becomes a bottom end of the bag. The following bag follows the bag, whose bottom end is the sealed portion.
