A form-fill-seal packaging machine has a pull-down mechanism (5) for advancing an elongated bag-making film, a longitudinal sealer (6) for sealing the film in the longitudinal direction to make a tube and a transverse sealer (7) for sealing the film transversely to form the bottoms and the tops of the bags. The machine is controlled such that the longitudinal sealer (6) is activated for a specified length of time whenever a ready signal is outputted to a weigher to request a discharge of articles to be packaged but the operations of the pull-down mechanism and the transverse sealer are not started unless a signal is received from the weigher, indicating that it has discharged articles as requested. <IMAGE> |
