An article to be packaged and a packaging bag for covering the article are supplied to heat sealing mechanisms which arrive at uniform time intervals, in synchronism with cycle timing of the respective heat sealing mechanisms. A vertically openable beak-shaped hopper and a sliding plate perform reciprocal movement at a uniform time interval along guides on both sides, and arrive at circulating sealing platforms. The hopper is inserted into an opening of the packaging bag hanging down from above, and conveys the packaging bag to the sealing platform whilst extending the same. In response to a relevant signal, a forward-and-reverse motor coupled to a ball screw causes the article to advance following the hopper by an insertion rod moving along the guides. If there is no resistance of the packaging bag on the opening- and-closing bars which open to opposite sides, a packaging bag absence signal is issued, and according to this signal, the insertion rod is withdrawn together with the hopper, leaving the article on the sliding plate, and subsequent advance timing of the hopper is controlled.
